Explanatory notes on parameters

Overview Relay applications This catalog contains the technical information which a design engineer requires in order to select a relay for his particular requirements. Bosch DC relays were originally designed for automotive applications. We recommend prior technical clarification for all other applications, especially where requirements, loading or ambient conditions differ from those applying to automotive applications.

Bosch DC relays are able to withstand exposure to extreme conditions and must comply with the following requirements: They must – switch high powers – function efficiently and reliably in a broad temperature range – be extremely resistant to vibration – have a long service life, and – be highly climate-proof. Bosch DC relays are used to switch electrical devices featuring high power levels or which are sensitive to voltage loss. Relays relieve the load on control switches and make for small voltage drops with economical conductor crosssections. And relays make simple interlock circuits possible.

Mini-relays and micro-relays are ideal for use where the available space is restricted. Multiple connectors, together with pre-tested wiring harnesses, ensure simple assembly and the lowest possible error rate. This applies in particular to OEM, but also to customer service. The following versions of mini-relays and microrelays are available: – Relays without mounting bracket. Easily plugged into buttable socket housings for screwing on – Relays with mounting bracket. Connected using a 5-pole socket housing Power relays can switch a nominal current of 50 A and more, and are suitable for switching motors, starting motors and other devices.

Parameters and definition of terms Definition of terms (to DIN 41 215, where standardized) The various parameters with their specific characteristic values permit the selection of the correct relay for a particular job. During its service life, every type of relay must fulfill defined tasks at the specified characteristic values. The response voltage is the value of the smallest excitation voltage which makes a relay respond, taking into account the ambient temperature and self-heating factors. The response time is the time that elapses between the closing of the exciter circuit to the first closing of an NO contact or the first opening of an NC contact. The operating voltage is the value of the excitation voltage at which the relay shows the characteristic data required for operation. The excitation voltage is the electrical voltage which permits the electric current to flow through the excitation winding and produce the excitation. The connection is made via terminals 1 and 2 or 85 and 86. The nominal value is the value of a variable (e.g. voltage, current, resistance) for which a relay, its parts and properties are designed or after which they are named. Correction factor The specifications for the energizing side apply at an ambient temperature of +20 °C. If the ambient temperature deviates from this figure, the correction factor K can be applied to convert the winding resistances, response voltages and release voltages. K = [1 + α(tu – 20 °C)] tu = actual ambient temperature or coil temperature α = 0.004 K–1 (mean temperature coefficient for copper).

The bounce time is the time that elapses between the first and last closing of a relay contact when the relay changes to another switching position. The release voltage is the value of the maximum excitation voltage at which the relay drops out, taking into account ambient temperature and self-heating factors. The release (dropout) time is the time that elapses between the opening of the exciter circuit and the first opening of an NO contact or the first closing of an NC contact. The switching voltage is the voltage which is present between the contacts when the electric circuit is open, once transient processes have settled. The voltage drop is the voltage at the relay terminals of a closed relay contact measured at a defined current. The overall resistance of the exciter circuit is the electrical resistance between the terminals 1 and 2 or 85 and 86.

Degrees of protection and operating modes Switching operations Response is the operation by which a relay is switched from its normal position to its operated position. Opening is an operation which results in the electrical contact being opened. Release (dropout) is the operation by which a relay is switched from its operated position to its normal position. A switching cycle comprises the single response and release of a relay. The number of switching operations comprises the total number of switching cycles. Closing is an operation which results in contact closure. With inductive loads and motors, a suppresser circuit, which can be set up parallel to the load with a free-wheeling diode, is required (see circuit).

The NO (Normally Open) contact is a relay contact which is open in the relay’s normal position and closes as the relay changes to its operated position.

6U D

The mechanical service life is defined as the number of switching cycles, without electrical loading of the contacts, during which the relay remains operational.

The NC (Normally Closed) contact is a relay contact which is closed in the relay’s normal position and opens as the relay changes to its operated position. The changeover contact is a contact assembly with three electrically isolated connections consisting of an NO contact an NC contact and a common contact spring. When the switch position changes, the closed contacts open first, followed by the closing of the other contacts (which up to that point were open).

Degrees of protection and operating modes Degrees of protection In accordance with DIN 40 050, the degree of protection is designated by a code which is always made up of the letters IP (Internal Protection) followed by two numbers signifying the actual level of protection. The first number indicates the

degree of protection against accidental contact and against the ingress of solid foreign bodies, the second number indicates the degree of protection against the ingress of water. If the degree of protection of one of a device’s

operational parts (e.g. terminals) differs from that of the main part of the device, then its code will be stated separately. The lower degree of protection is given first. Example: Terminals IP 20 – Housing IP 5K4.

Recommended assembly method: The socket housing should be soldered to the PC board with the relay inserted, as then the receptacles are automatically centered and the PC board is not put under strain by plugging in the relay. If the relay is plugged in after the socket housing has been soldered in place, take care to care to ensure that the receptacle locking lance is up against the socket-housing stop, so that the soldered connection is not subject to pressure.

Notes Compact design. High degree of corrosion protection due to use of glass-fiber-reinforced polyamide for baseplate and cap. High degree of protection against splash water thanks to drip rim between cap and baseplate. Leakage-current barriers in baseplate. Designed-in ventilation by means of “labyrinth”. Option of “heavy duty” version with tungsten leading contact.

Automotive applications: Load-reducing relay for switches. Operating relay for starting motors. Switch-on relay for hydraulic assemblies, blowers and heaters for the passenger compartment, engine-cooling fans. Pre-heating device for diesel starting systems. Motor relay for antilock braking system (ABS). Battery cutoff relay.

Method of operation of leading contact 1

Circuit diagrams 2

1. Closure of leading contact Coil energized; current flows in leading contact for a fraction of a second. 2. Closure of main contact Coil energized; current flows in main contact. The characteristics of the tungsten leading contact make it ideal for the considerable loads resulting from the separation arc when contacts are opening (inductive loads). The main contact ensures efficient current flow with minimum voltage losses. The tungsten leading contact (late-opening when the contacts open) ensures that the main contacts are not subject to separation arcs.

The pull-in and hold-in windings are connected in parallel before response and the resulting high making current (approx. 13 A max.) guarantees rapid, reliable response. After the relay has operated, the electric circuit of the pull-in winding is interrupted and the hold-in winding holds the relay in its operated position at a current of approx. 1 A.

Application Together with the 3-way catalytic converter, the Lambda oxygen sensor and the Lambda closed-loop control represent today's most effective exhaust-emissions control system for the spark-ignition (SI) engine. At present, there is no alternative available which even approaches the low exhaust-emission figures obtained with this system. Since 1976, Bosch has been producing the Lambda sensor for exhaust-emission control systems in the USA and Europe. The Bosch Lambda sensor was the world's first oxygen sensor to go into operation, and played a decisive role in the breakthrough of exhaust-emissions control using the closed-loop-controlled 3-way catalytic converter. In the meantime, this sensor has proved itself in millions of vehicles.

1,05

The Lambda sensor is screwed into the exhaust system. It is a detecting element for measuring the residual oxygen in the exhaust gas which, since it provides a precise indication of whether combustion is complete or not, is highly suitable as the measured quantity for closed-loop control of the A/F ratio. The Lambda-sensor output signal not only provides an indication of instantaneous A/F mixture composition, but it also follows any A/F mixture changes. The mixture-formation system controls the supply of fuel to the engine in accordance with the signal from the Lambda sensor so that a stoichiometric A/F ratio "Lamda" of λ = 1 is maintained.

λ

1,1

Lambda is the dimension used to define the mixture's A/F ratio.

λ=

instantaneous A/F ratio stoichiometric A/F ratio

Referred to the stoichiometric ratio λ = 1, a lean mixture (λ > 1) contains more air, and a rich mixture (λ < 1) contains less air. Heated or unheated Lambda sensors are used depending upon exhaust-system design and operating conditions. The extensive Bosch Lambda sensor program covers a wide variety of variants. The Lamda sensor is also used outside the automotive sector. For instance, for the closed-loop control of gas engines or of gas/oil burners.

Lambda Sensor

Design (Fig. 1) The Lambda sensor operates according to the principle of a galvanic oxygen concentration cell with solid electrolyte (Nernst principle). The solid-state electrolyte comprises a gas-impermeable ceramic element of circonium dioxide which is stabilized with yttrium oxide and closed at one end. The ceramic element's inside and outside surfaces are provided with electrodes composed of a thin, gas-permeable, porous layer of platinum which on the one side has an influence on the sensor characteristic due to its catalytic effects, and on the other serves for electrical contacting. On the outside surface of the sensor ceramic which protrudes into the exhaustgas stream, the platinum layer is itself coated with a highly porous ceramic layer. This robust layer prevents the catalytic platinum layer being attacked by the corrosive and erosive effects of the deposits in the exhaust gas, and thus ensures long-term sensor stability.

Fig. 3: Engine with exhaust-gas system 1 Exhaust-gas system with catalytic converter, 2 Lambda sensor(s)

Operation (Fig. 2) The Lambda sensor is installed in the engine's exhaust-gas system at a point which throughout the engine's complete operating range provides the temperature which is necessary for efficient sensor functioning. The sensor protrudes into the exhaust gas, design being such that one electrode surface is surrounded by the exhaust gas and the other is connected to the atmosphere. Even under excess-fuel conditions, there is always residual oxygen in the SI engine's exhaust gas (at λ = 0.95, approx. 0.1 ... 0.3% by volume). The use of porous platinum electrodes means that at the electrode surface, catalytic conversion of this residual oxygen can take place with the carbon monoxide (CO), hydrocarbons (HC), and the hydrogen present in the exhaust gas. The residual oxygen remaining after complete conversion is a function of the exhaustgas Lambda value, and is measured by the Lambda (oxygen) sensor. During transition from a lean mixture (high residualoxygen content) to a rich mixture (very low residual-oxygen content), the residual-oxygen content reduces abruptly by several powers of 10 in the stoichiometric region λ = 1 of air-fuel mixture. This results in the sudden jump of sensor voltage output at λ = 1. The sensor voltage and its

1 2

internal resistance depend upon temperature. Reliable closed-loop control takes place at temperatures above 350°C (for the unheated sensor) and above 150°C (for the heated sensor).

Installation (Fig. 3) The Lambda sensor is installed in the exhaust system at a point which, besides featuring exhaust-gas composition which is representative for all cylinders, must also be hot enough (at least 350°C for the unheated sensor and 150° for the heated sensor). A sensor life corresponding to more than 160,000 km as driven by the vehicle can be achieved if the specifications for sensor loading are complied with.

The Lambda closed-loop (feedback) control The control loop comprises the engine (controlled system), the Lambda sensor (measuring element), the controller in the ECU, and the injectors (actuators). The controlled variable is the residual oxygen in the exhaust gas. The object of the closed-loop control is to generate an optimal A/F mixture by adjusting the quantity of fuel (manipulated variable) injected by the injectors (actuators). The Lambda closed-loop control automatically takes into account special modes such as start, acceleration, and full load.

The sensor's active ceramic body is held in position and sealed in the housing by means of a "finger-shaped" ceramic support tube and a disc spring. A contact element between the support tube and the active ceramic body is used to provide contacting from the inner electrode to the connection cable. The outer electrode is connected to the sensor housing by the metal seal ring. The sensor's internal elements are fastened and aligned by a protective metal sleeve which, apart from serving as a support for the disc spring, also protects the interior of the sensor against contamination. The cable is crimped to the end of the contact element which protrudes from the sensor, and is sealed off against dampness and mechanical damage by means of a temperature-resistant PTFE cap. In order to keep the exhaust-gas combustion deposits away from the sensor ceramic, the end of the housing which protrudes into the exhaust-gas flow is protected by a specially shaped tube having slots designed to provide highly effective protection against the effects of excessive thermal and chemical stresses.

Heated Lambda sensor LSH (Fig.5)

Design Basically, the heated Lambda sensor is identical to the unheated version. The active sensor ceramic is heated from the inside by a ceramic heating element so that it remains above the 350°C function limit independent of the exhaust-gas temperature. The ceramic heating element has a PTC characteristic so that it heats up quickly and needs only very little power when the exhaust gas has heated up. The heating-element connections are fully decoupled from the sensor signal line (R ≥ 30 MΩ). In contrast to the unheated version, the heated sensor is equipped with a protective tube with small slots for exhaust-gas passage. This increases the protection against contamination and prevents the sensor ceramic cooling down excessively when the exhaust gas is still "cold".

trol electronics for the pump and sensor cells as required for generation of the sensor signal, but also the control electronics for controlling the sensor's temperature. As a result, novel applications become possible: – Control also possible at λ > 1 and λ < 1, – Continuous Lambda control at λ = 1, – Diesel-engine control, – Lean-burn concept for SI engines, – Gas-engine control.

The broadband Lambda sensor is a planar dual-cell limit-current sensor. Its modular construction, combined with planar techniques, makes it possible to integrate a number of additional functions. The fact that the LSU sensor is a combination of a Nernst concentration cell (sensor cell) and a pump cell for oxygenion transport, means that it can also measure accurately in lean and rich regions, not only at λ = 1 (Fig. 9). Each sensor is individually calibrated. Special control electronics are required for the LSU sensor (evaluation circuit) This contains not only the internal con-

From the construction viewpoint, the major differences between the LSF sensor and the LSH sensor are as follows: – The LSF sensor element is fixed in the sensor housing by means of a ceramic seal packing. – The double-wall protective tube was specially designed for the planar sensor and provides the sensor element with highly effective protection against excessive thermal and mechanical stresses.

The planar Lambda sensor has been developed from the proven tube-type ("finger-version") sensor. Functionally, with its voltage curve jump at λ = 1, it corresponds to the heated finger version, while at the same time providing the basic technology for further ceramic-type sensors. In contrast to the finger sensor though, the planar sensor uses ceramic foils as the solid-state electrolyte. Screen-printing techniques are employed for producing the individual functional layers (electrodes, protective layers, etc.). The printed foils are laminated one on top of the other, and this principle enables a heater to be integrated in the sensor element (Figs. 7 and 8).

CAN-Bus Controller Area Network

Present-day motor vehicles are equipped with a large number of electronic control units (ECUs) which have to exchange large volumes of data with one another in order to perform their various functions. The conventional method of

doing so by using dedicated data lines for each link is now reaching the limits of its capabilities. On the one hand, it makes the wiring harnesses so complex that they become unmanageable, and on the other the finite number of pins

on the connectors becomes the limiting factor for ECU development. The solution is to be found in the use of specialized, vehicle-compatible serial bus systems among which the CAN has established itself as the standard.

Applications There are four areas of application for CAN in the motor vehicle, each with its own individual requirements:

Bus configuration CAN operates according to the multimaster principle, in which a linear bus structure connects several ECUs of equal priority rating (Fig. 1). The advantage of this type of structure lies in the fact that a malfunction at one node does not impair bus-system access for the remaining devices. Thus the probability of a total system failure is substantially lower than with other logical architectures (such as ring or active star structures). When a ring or active star structure is employed, failure at a single node or at the CPU is sufficient to cause a total failure.

they then repeat the transmission attempt as soon as the bus is free again.

Real-time applications Real-time applications, in which electrical systems such as Motronic, transmissionshift control, electronic stability-control systems are networked with one another, are used to control vehicle dynamics. Typical data transmission rates range from 125 kbit/s to 1 Mbit/s (high-speed CAN) in order to be able to guarantee the real-time characteristics demanded. Multiplex applications Multiplex applications are suitable for situations requiring control and regulation of body-component and luxury/convenience systems such as air conditioning, central locking and seat adjustment. Typical data transmission rates are between 10 kbits and 125 kbit/s (low-speed CAN). Mobile-communications applications Mobile-communications applications connect components such as the navigation system, cellular phone or audio system with central displays and controls. The basic aim is to standardize control operations and to condense status information so as to minimize driver distraction. Data transmission rates are generally below 125 kbit/s; whereby direct transmission of audio or video data is not possible. Diagnostic applications Diagnostic applications for CAN aim to make use of existing networking for the diagnosis of the ECUs incorporated in the network. The use of the “K” line (ISO 9141), which is currently the normal practice, is then no longer necessary. The data rate envisaged is 500 kbit/s.

Content-based addressing Addressing is message-based when using CAN. This involves assigning a fixed identifier to each message. The identifier classifies the content of the message (e.g., engine speed). Each station processes only those messages whose identifiers are stored in its acceptance list (message filtering, Fig. 2). Thus CAN requires no station addresses for data transmission, and the nodes are not involved in administering system configuration. This facilitates adaptation to variations in equipment levels. Logical bus states The CAN protocol is based on two logical states: The bits are either “recessive” (logical 1) or “dominant” (logical 0). When at least one station transmits a dominant bit, then the recessive bits simultaneously sent from other stations are overwritten. Priority assignments The identifier labels both the data content and the priority of the message being sent. Identifiers corresponding to low binary numbers enjoy a high priority and vice versa. Bus access Each station can begin transmitting its most important data as soon as the bus is unoccupied. When several stations start to transmit simultaneously, the system responds by employing “Wired-AND” arbitration to sort out the resulting contentions over bus access. The message with the highest priority is assigned first access, without any bit loss or delay. Transmitters respond to failure to gain bus access by automatically switching to receive mode;

Message format CAN supports two different data-frame formats, with the sole distinction being in the length of the identifier (ID). The standardformat ID is 11 bits, while the extended version consists of 29 bits. Thus the transmission data frame contains a maximum of 130 bits in standard format, or 150 bits in the extended format. This ensures miminal waiting time until the subsequent transmission (which could be urgent). The data frame consists of seven consecutive bit fields (Fig. 3 ): “Start of frame” indicates the beginning of a message and synchronizes all stations. “Arbitration field” consists of the message’s identifier and an additional control bit. While this field is being transmitted, the transmitter accompanies the transmission of each bit with a check to ensure that no higher-priority message is being transmitted (which would cancel the access authorization). The control bit determines whether the message is classified under “data frame” or “remote frame”. “Control field” contains the code indicating the number of data bytes in the data field. “Data field’s” information content comprises between 0 and 8 bytes. A message of data length 0 can be used to synchronize distributed processes. “CRC field” (Cyclic Redundancy Check) contains the check word for detecting possible transmission interference. “Ack field” contains the acknowledgement signals with which all receivers indicate receipt of non-corrupted messages. “End of frame” marks the end of the message.

Transmitter initiative The transmitter will usually initiate a data transfer by sending a data frame. However, the receiver can also request data from the transmitter. This involves the receiver sending out a “remote frame”. The “data frame” and the corresponding “remote frame” have the same identifier. They are distinguished from one another by means of the bit that follows the identifier. Error detection CAN incorporates a number of monitoring features for detecting errors. These include: – 15 Bit CRC (Cyclic Redundancy Check): Each receiver compares the CRC sequence which it receives with the calculated sequence. – Monitoring: Each transmitter compares transmitted and scanned bit. – Bit stuffing: Between “start of frame” and the end of the “CRC field”, each “data frame” or “remote frame” may contain a maximum of 5 consecutive bits of the same polarity. The transmitter follows up a sequence of 5 bits of the same polarity by inserting a bit of the opposite polarity in the bit stream; the receivers eliminate these bits as the messages arrive. – Frame check: The CAN protocol contains several bit fields with a fixed format for verification by all stations. Error handling When a CAN controller detects an error, it aborts the current transmission by sending an “error flag”. An error flag consists of 6 dominant bits; it functions by deliberately violating the conventions governing stuffing and/or formats.

Bus

Fault confinement with local failure Defective stations can severely impair the ability to process bus traffic. Therefore, the CAN controllers incorporate mechanisms which can distinguish between intermittent and permanent errors and local station failures. This process is based on statistical evaluation of error conditions. Implementations In order to provide the proper CPU support for a wide range of different requirements, the semiconductor manufacturers have introduced implementations representing a broad range of performance levels. The various implementations differ neither in the message they produce, nor in their arrangements for responding to errors. The difference lies solely in the type of CPU support required for message administration. As the demands placed on the ECU’s processing capacity are extensive, the interface controller should be able to ad-

Message Frame

minister a large number of messages and expedite data communications with, as far as possible, no demands on the CPU’s computational resources. Powerful CAN controllers are generally used in this type of application. The demands placed on the controllers by multiplex systems and present-day mobile communications are more modest. For that reason, more basic and less expensive chips are preferred for such uses. Standardization CANs for data exchange in automotive applications have been standardized both by the ISO and the SAE – in ISO 11519-2 for low-speed applications ≤ 125 kbit/s and in ISO 11898 and SAE J 22584 (cars) and SAE J 1939 (trucks and busses) for high-speed applications >125 kbit/s. There is also an ISO standard for diagnosis via CAN (ISO 15765 – Draft) in the course of preparation.

Steering-wheel-angle sensor Measurement of angles from –780° to +780° φ CAN P “True-Power-On” function. P Multiple-rotation function. P CAN interface.

Application The steering-wheel-angle sensor was developed for use with vehicle dynamics systems (ESP*). Due to integral plausibility tests, and special self-diagnosis functions, this steeringwheel-angle sensor is highly suitable for application in safety systems. Design and function When the steering wheel is turned it rotates a gearwheel which in turn drives two other special measuring gears which incorporate magnets. AMR elements which change their resistance as a function of the direction of magnetic field register the angular position of the magnets. These analog measured values are then inputted to the microprocessor via an A/D converter. The number of teeth on one measuring gear differs to that on the other, which means that they therefore change their rotational position at different speeds. By combining both the actual angles of rotation, it is possible to calculate the total angle of rotation. After a number of rotations of the steering wheel, each of the measuring gears has returned to its initial position. Using this principle, it becomes possible to cover a measurement range of several steering-wheel rotations without the need to use a revolution counter. The steering-wheel angle is outputted in the form of an absolute angle across the total steering-column rotation range. One of this sensor’s special features is the fact that the (correct) angle-of-rotation is available immediately the ignition is switched on, without the steering wheel having been moved (“True-Power-On”). The steeringwheel angle and the steering-wheel speed are outputted via CAN. * ESP = Electronic Stability Program

Voltage ratio

Design and function The throttle-valve angular-position sensor is a potentiometric sensor with a linear characteristic curve. In electronic fuel injection (EFI) engines it generates a voltage ratio which is proportional to the throttle valve’s angle of rotation. The sensor’s rotor is attached to the throttle-valve shaft, and when the throttle valve moves, the sensor’s special wipers move over their resistance tracks so that the throttle’s angular position is transformed into a voltage ratio. The throttle-valve angular-position sensor’s are not provided with return springs.

Application These sensors are used in automotive applications for measuring the angle of rotation of the throttle valve. Since these sensors are directly attached to the throttlevalve housing at the end of the throttleshaft extension, they are subject to extremely hostile underhood operating conditions. To remain fully operational, they must be resistant to fuels, oils, saline fog, and industrial climate.

Yaw sensor (gyrometer) with micromechanical acceleration sensor Ω U P Compact system design with highly integrated electronics. P Insensitive to mechanical or electrical interference. P Simultaneous measurement of yaw rate and acceleration vertical to the rotary axis. P Extensive yaw-rate measuring range from 0.2...100 degrees per second (corresponds to 2...1,000 rotations per hour). P Capacitive measuring concept. Design The complete unit is comprised of a yaw sensor and an acceleration sensor, together with evaluation electronics. These components are all mounted on a hybrid and hermetically sealed in a metal housing. Application This sensor is used in automotive engineering for the vehicle dynamics control (Electronic Stability Program, ESP) and measures the vehicle’s rotation around its vertical axis, while at the same time measuring the acceleration at right angles to the driving direction. By electronically ervaluating the measured values, the sensor is able to differentiate between normal cornering and vehicle skidding movements. Operating principle Two oscillatory masses each have a conductor attached through which alternating current (AC) flows. Since both of the masses are located in a constant magnetic field, they are each subjected to an electrodynamic force which causes them to oscillate. If the masses are also subjected to a rotational movement, Coriolis forces are also generated. The resulting Coriolis acceleration is a measure for the yaw rate.The linear acceleration values are registered by a separate sensor element.

Application Inductive rotational-speed sensors of this type are suitable for numerous applications involving the registration of rotational speeds. Depending on design, they measure engine speeds and wheel speeds for ABS systems, and convert these speeds into electric signals. Design and function The soft-iron core of the sensor is surrounded by a winding, and located directly opposite a rotating toothed pulse ring with only a narrow air gap separating the two. The soft-iron core is connected to a permanent magnet, the magnetic field of which extends into the ferromagnetic pulse ring and is influenced by it. A tooth located directly opposite the sensor concentrates the magnetic field and amplifies the magnetic flux in the coil, whereas the magnetic flux is attenuated by a tooth space. These two conditions constantly follow on from one another due to the pulse ring rotating with the wheel. Changes in magnetic flux are generated at the transitions between the tooth space and tooth (leading tooth edge) and at the transitions between tooth and tooth space (trailing tooth edge). In line with Faraday’s Law, these changes in magnetic flux induce an AC voltage in the coil, the frequency of which is suitable for determining the rotational speed.

The sensor generates one output pulse per tooth. The pulse amplitude is a function of the air gap, together with the toothed ring’s rotational speed, the shape of its teeth, and the materials used in its manufacture. Not only the output-signal amplitude increases with speed, but also its frequency. This means that a minimum rotational speed is required for reliable evaluation of even the smallest voltages. A reference mark on the pulse ring in the form of a large “tooth space” makes it possible not only to perform rotational-speed measurement, but also to determine the pulse ring’s position. Since the toothed pulse ring is an important component of the rotational-speed measuring system, exacting technical demands are made upon it to ensure that reliable, precise information is obtained. Pulse-ring specifications are available on request. Explanation of symbols UA Output voltage n Rotational speed s Air gap

Hall-effect rotational-speed sensors Digital measurement of rotational speeds n, φ, s U P Precise and reliable digital measurement of rotational speed, angle, and distance travelled. P Non-contacting (proximity) measurement. P Hall-IC in sensor with opencollector output. P Insensitive to dirt and contamination. P Resistant to mineral-oil products (fuel, engine lubricant).

Design Hall sensors comprise a semiconductor wafer with integrated driver circuits (e.g. Schmitt-Trigger) for signal conditioning, a transistor functioning as the output driver, and a permanent magnet. These are all hermetically sealed inside a plastic plugtype housing. Application Hall-effect rotational-speed sensors are used for the non-contacting (proximity), and therefore wear-free, measurement of rotational speeds, angles, and travelled distances. Compared to inductive-type sensors, they have an advantage in their output signal being independent of the rotational speed or relative speed of the rotating trigger-wheel vane. The position of the tooth is the decisive factor for the output signal. Adaptation to almost every conceivable application requirement is possible by appropriate tooth design. In automotive engineering, Hall-effect sensors are used for information on the momentary wheel speed and wheel position as needed for braking and drive systems (ABS/TCS), for measuring the steering-wheel angle as required for the vehicle dynamics control system (Electronic Stability Program, ESP), and for cylinder identification. Operating principle Measurement is based upon the Hall effect which states that when a current is passed through a semiconductor wafer the socalled Hall voltage is generated at right angles to the direction of current. The magnitude of this voltage is proportional to the magnetic field through the semiconductor. Protective circuits, signal conditioning circuits, and output drivers are assembled directly on this semiconductor. If a magnetically conductive tooth (e.g. of soft iron) is moved in front of the sensor, the magnetic field is influenced arbitrarily as a function of the trigger-wheel vane shape. In other words, the output signals are practically freely selectable.

Acceleration sensor Measurement of acceleration up to ±5 g a U P Ratiometric output signal. P Temperature-compensated. P Low pyroelectric sensitivity. P Hermetically sealed housing. P High-level EMC. P Overvoltage protection. P Short-circuit proof. P Protected against reverse polarity.

Design and function The sensor element comprises a “bending element” consisting of two anti-parallel polarized piezoelectric layers. If acceleration forces are applied to this bending element, mechanical tension is caused which in turn results in a charge of electricity at the bending-element surfaces. This charge is evaluated by a hybrid circuit. The sensor can measure in the horizontal and in the vertical measurement directions when mounted appropriately, whereby the measurement direction is usually vertical to the clamping surface. An output signal UA > U0 is generated for vertical upwards acceleration of the clamping surface, whereas the corresponding downward acceleration generates a signal UA < U0. The output voltage UA has a cosine relationship to the angle between the sensor measurement direction and the direction of acceleration. Taking an angle of 15°, this produces a (calculated) signal reduction of 3.4%.

Applications In automotive engineering, this sensor is used to rule out the chance of faulse diagnosis in the engine electronics. It registers the vehicle accelerations which are the direct result of fluctuations in crankshaft speed. In order to ascertain whether these crankshaft-speed fluctuations result from ignition misfire or a poor road surface, the latest engine-management systems also register the ignition misfires of the individual cylinders.

Suitable for pcb mounting. 0 273 101 141 With two sensing directions offset to each other by 90°. Suitable for pcb mounting. 0 273 101 150 With one sensing direction only. In this direction, acceleration leads to a 180° phase shift of channel A, whereas the channel B phase shift is 0°. Suitable for pcb mounting. 0 273 101 131 Applications Used in automotive occupant-protection systems for triggering the airbag, the seatbelt tightener, the roll-over bar, or the seatbelt locking systems. Used for instance as the impact sensor for monitoring impact loads during transportation. Since the lower frequency limit is 0.9 Hz, this sensor can only be used to register acceleration changes. Design and function The heart of this acceleration sensor is a piezo-ceramic strip of polycrystalline sintered material. When electrically polarized, this material displays a piezoelectrical effect: That is, when pressure is applied, the mechanical loading results in charge separation, or a voltage which can then be picked-off by electrodes. The piezo bending element comprises a bonded structure containing two inversely polarized piezo strips, the so-called bimorphous strips. These have electrodes, and are bonded to a center electrode. This configuration has the advantage that the pyroelectrical signals caused by temperature fluctuations compensate each other.

When subjected to acceleration, the piezoceramic bends by as much as 10–7 m. For signal processing, the sensor is provided with a hybrid circuit which is comprised of an impedance converter, a filter, and an amplifier. These serve to define the sensitivity and effective frequency range. The filter removes the HF signal components. The lower frequency limit of 0.6 Hz is defined by the piezo element itself. Using a supplementary test input, the sensor’s electronic functions can be monitored as well as piezo-strip integrity.

Test signal A fully operational sensor generates a positive output pulse when +5V are briefly applied across its test input. If there is an open-circuit in the signal path, this output pulse will be missing, and if the bimorphous strip is broken the signal will exceed +5V. For the versions with two bimorphous strips, the output pulse must appear at each output.

Applications This acceleration sensor is used in vehicles as one of the components for the front airbag. Depending upon installation position in the passenger compartment, it can be used to measure longitudinal or transverse acceleration (referred to the vehicle’s direction of travel). Design and function These acceleration sensors rely on a capacitive measuring principle. Lateral sensing direction (in the component level). Acceleration causes the seismic mass to deflect in the x-direction. This seismic mass is suspended on wave-shaped bending springs. One electrode set is connected to the seismic mass (comb-like structure) and moves along with the particular acceleration. These movable electrodes are designed as capacitor plates and are also provided with immovable counter-electrodes which are separated from each other by a narrow air gap. The application of a capacitive differential circuit with two capacitors results in a reduction of the non-linearity of the signal evaluation. Overload stops are provided as a protection against over-acceleration. These prevent direct contact between the electrodes (combs). Mechanical sensitivity is defined by the geometrical shape of the springs. Changes in C1 and C2 are registered and changed to a corresponding voltage by a capacity/voltage converter.

Piezoelectric vibration sensors Measurement of structure-borne noise/acceleration a U P Reliable detection of structure-borne noise for protecting machines and engines. P Piezo-ceramic with high degree of measurement sensitivity. P Sturdy compact design.

Applications Vibration sensors of this type are suitable for the detection of structure-borne acoustic oscillations as can occur for example in case of irregular combustion in engines and on machines. Thanks to their ruggedness, these vibration sensors can be used even under the most severe operating conditions. Areas of application – Knock control for internal-combustion engines – Protection of machine tools – Detection of cavitation – Monitoring of bearings – Theft-deterrent systems Design and function On account of its inertia, a mass exerts compressive forces on a ring-shaped piezo-ceramic element in time with the oscillation which generates the excitation. Within the ceramic element, these forces result in charge transfer within the ceramic and a voltage is generated between the top and bottom of the ceramic element. This voltage is picked-off using contact discs – in many cases it is filtered and integrated – and made available as a measuring signal. In order to route the vibration directly into the sensor, vibration sensors are securely bolted to the object on which measurements take place. Measurement sensitivity Every vibration sensor has its own individual response characteristic which is closely linked to its measurement sensitivity. The measurement sensitivity is defined as the output voltage per unit of acceleration due to gravity (see characteristic curve). The production-related sensitivity scatter is acceptable for applications where the primary task is to record that vibration is occurring, and not so much to measure its severity. The low voltages generated by the sensor can be evaluated using a high-impedance AC amplifier.

Installation instructions The sensor’s metal surfaces must make direct contact. No washers of any type are to be used when fastening the sensors. The mounting-hole contact surface should be of high quality to ensure low-resonance sensor coupling at the measuring point. The sensor cable is to be laid such that there is no possibility of sympathetic oscillations being generated. The sensor must not come into contact with liquids for longer periods.

Piezoelectric vibration sensors Signal-evaluation module a U P Choice of 4 selectable sensor inputs or 2 symmetrical inputs. P Programmable amplification. P Programmable bandpass filter. P External calibration unnecessary. P Integral programmable frequency divider. P Analog stage with signal test. P Suitable for a wide variety of microcomputers. P PLCC28 housing. Technical data / Range Applications Evaluation of the analog signals from piezoelectric sensors (vibration sensors). Design and function The analog signals are evaluated by a circuit integrated in the module. The circuit contains a programmable amplifier, a bandpass filter, a rectifier, an integrator, and control logic circuitry. The use of “SC” circuit engineering ensures that operation remains insensitive to interference, and that there is no necessity for external calibration. It is an easy matter to use this fully programmable circuit for a variety of applications. The start and end of the integration are controlled through the “measuring window” input. For a variety of different pulse frequencies applied from outside (8 steps of 1...16 MHz), a frequency divider which is programmed through 3 inputs, generates the system clock for the analog stage, and the test frequencies (9 mid-frequencies from 5...16 kHz) depending upon the setting of the filter. The internal pulse frequency can be changed from nominal 100 kHz to values between 50 kHz and 150 kHz by changing the quartz frequency. At the same time, a shift of the band-filter mid-frequencies, the test frequencies, and the integration time constants also takes place. Note Due to its having MOS inputs, this module is to be handled very carefully. It is not to be touched directly and a MOS workstation is to be used. Operating-voltage switch-on is only to take place with a voltage gradient < 1 V · µs–1.

P High accuracy. P EMC protection better than 100 V m–1. P Temperature-compensated.

Applications On internal-combustion engines, this sensor is used to measure the differential pressure between the intake-manifold pressure of the drawn-in air and a reference pressure which is inputted through a hose. Design and function The piezoresistive pressure-sensor element and suitable electronic circuitry for signal amplification and temperature compensation are mounted on a silicon chip. The measured pressure is applied to the rear side of the silicon diaphragm. The reference pressure is applied from above to the diaphragm’s active surface. Thanks to a special coating, both sides of the diaphragm are insensitive to the gases and liquids which are present in the intake manifold. Installation information The sensor is designed for mounting on a horizontal surface of the vehicle’s intake manifold. The pressure fitting extends into the manifold and is sealed-off to atmosphere by an O-ring. Care must be taken, by ensuring appropriate mounting, that condensate does not form in the pressure cell or in the reference opening. Generally speaking, installation is to be such that liquids cannot accumulate in either the sensor or the pressure hose. Water in the sensor leads to malfunctions when it freezes.

Differential-pressure sensors Measurement of pressures in gases and liquid mediums from –2.5 kPa to +3.75 kPa p U P Resistant to the monitored medium. P Piezoresistive sensor element. P Integrated protection against humidity.

Application In automotive applications, this type of pressure sensor is used for measuring fueltank pressure. In the process, a differential pressure is established referred to the ambient pressure. Design and function A micromechanical pressure element with diaphragm and connector fitting is the most important component in this differentialpressure sensor. The diaphragm is resistant to the effects of the monitored medium. The measurement is carried out by routing the monitored medium through the pressure connector and applying the prevailing pressure to the piezoresistive sensor element. This sensor element is integrated on a silicon chip together with electronic circuitry for signal amplification and temperature compensation. The silicon chip is surrounded by a TO-type housing which forms the inner sensor cell. The surrounding pressure is applied to the active surface through an opening in the cap and a reference fitting. The active surface is protected against moisture by Silicagel. The pressure sensor generates an analog signal which is ratiometric referred to the supply voltage. Installation instructions The sensor is designed for horizontal mounting on a horizontal surface. In case of non-horizontal mounting, each case must be considered individually. Generally speaking, installation is to be such that liquids cannot accumulate in the sensor or in the pressure hose. Water in the sensor leads to malfunctions when it freezes.

p U

P Thick-film pressuremeasuring element ensures a high degree of measurement sensitivity. P Thick-film sensor element and IC on the same substrate guarantee problem-free signal transmission. P Integrated evaluation circuit for signal amplification, temperature compensation, and characteristic-curve adjustment P Sensor enclosed by robust housing. Design and function The heart of this sensor is the “sensor bubble” (pressure-measuring element) produced using 100% thick-film techniques. It is hermetically sealed on a ceramic substrate and contains a given volume of air at a reference pressure of approx. 20 kPa. Piezo-resistive thick-film strain gauges are printed onto the bubble and protected with glass against aggressive media. The strain gauges are characterized by high measurement sensitivity (gauge factor approx. 12), as well as by linear and hysteresis-free behavior. When pressure is applied, they convert mechanical strain into an electric signal. A full-wave bridge circuit provides a measurement signal which is proportional to the applied pressure, and this is amplified by a hybrid circuit on the same substrate. It is therefore impossible for interference to have any effect through the leads to the ECU. DC amplification and individual temperature compensation in the –40 °C...+125 °C range, produce an analog, ratiometric (i.e. proportional to the supply voltage UV) output voltage UA. The pressure sensors are resistant to gauge pressures up to 600 kPa. Outside the temperature range 10 °C...85 °C the permissible tolerance increases by the tolerance multiplier. To protect the sensors, the stipulated maximum values for supply voltage, operatingtemperature, and maximum pressure are not to be exceeded.

Absolute-pressure sensors in micromechanical hybrid design Measurement of pressures in gases up to 400 kPa

p U

P High accuracy. P EMC protection better than 100 V m–1. P Temperature-compensated. P Version with additional integral temperature sensor.

Applications This sensor is used to measure the absolute intake-manifold pressure. On the version with integral temperature sensor, the temperature of the drawn-in air flow is also measured. Design and function The piezoresistive pressure-sensor element and suitable electronic circuitry for signalamplification and temperature compensation are mounted on a silicon chip. The measured pressure is applied from above to the diaphragm’s active surface. A reference vacuum is enclosed between the rear side and the glass base. Thanks to a special coating, both pressure sensor and temperature sensor are insensitive to the gases and liquids which are present in the intake manifold. Installation information The sensor is designed for mounting on a horizontal surface of the vehicle’s intake manifold. The pressure fitting together with the temperature sensor extend into the manifold and are sealed-off to atmosphere by O-rings. By correct mounting in the vehicle (pressure-monitoring point on the top at the intake manifold, pressure fitting pointing downwards etc.) it is to be ensured that condensate does not collect in the pressure cell.

Piezoresistive absolute-pressure sensor with moulded cable Measurement of pressures in gases up to 400 kPa

p U

P Pressure-measuring element with silicon diaphragm ensures extremely high accuracy and long-term stability. P Integrated evaluation circuit for signal amplification and characteristic-curve adjustment. P Very robust construction.

Applications This type of absolute-pressure sensor is highly suitable for measuring the boost pressure in the intake manifold of turbocharged diesel engines. They are needed in such engine assemblies for boostpressure control and smoke limitation. Design and function The sensors are provided with a pressureconnection fitting with O-ring so that they can be fitted directly at the measurement point without the complication and costs of installing special hoses. They are extremely robust and insensitive to aggressive media such as oils, fuels, brake fluids, saline fog, and industrial climate. In the measuring process, pressure is applied to a silicon diaphragm to which are attached piezoresistive resistors. Using their integrated electronic circuitry, the sensors provide an output signal the voltage of which is proportional to the applied pressure. Installation information The metal bushings at the fastening holes are designed for tightening torques of maximum 10 N · m. When installed, the pressure fitting must point downwards. The pressure fitting’s angle referred to the vertical must not exceed 60°. Tolerances In the basic temperature range, the maximum pressure-measuring error ∆p (referred to the excursion: 400 kPa–50 kPa = 350 kPa) is as follows: Pressure range 70...360 kPa As-new state ±1.0 % After endurance test ±1.2 % Pressure range < 70 and > 360 kPa (linear increase) As-new state ±1.8 % After endurance test ±2.0 %

3 Applications These monolithic integrated silicon pressure sensors are high-precision measuring elements for measuring the absolute pressure. They are particularly suitable for operations in hostile environments, for instance for measuring the absolute manifold pressure in internal-combustion engines. Design and function The sensor contains a silicon chip with etched pressure diaphragm. When a change in pressure takes place, the diaphragm is stretched and the resulting change in resistance is registered by an evaluation circuit. This evaluation circuit is integrated on the silicon chip together with the electronic calibration elements. During production of the silicon chip, a silicon wafer on which there are a number of sensor elements, is bonded to a glass plate. After sawing the plate into chips, the individual chips are soldered onto a metal base complete with pressure connection fitting. When pressure is applied, this is directed through the fitting and the base to the rear side of the pressure diaphragm. There is a reference vacuum trapped underneath the cap welded to the base. This permits the absolute pressure to be measured as well as protecting the front side of the pressure diaphragm. The programming logic integrated on the chip performs a calibration whereby the calibration parameters are permanently stored by means of thyristors (Zener-Zapping) and etched conductive paths. The calibrated and tested sensors are mounted in a special housing for attachment to the intake manifold.

56

Signal evaluation The pressure sensor delivers an analog output signal which is ratiometric referred to the supply voltage. In the input stage of the downstream electronics, we recommend the use of an RC low-pass filter with, for instance, t = 2 ms, in order to suppress any disturbance harmonics which may occur. In the version with integrated temperature sensor, the sensor is in the form of an NTC resistor (to be operated with series resistor) for measuring the ambient temperature. Installation information When installed, the pressure connection fitting must point downwards in order that condensate cannot form in the pressure cell.

7

Construction Sensors with housing: This version is equipped with a robust housing. In the version with temperature sensor, the sensor is incorporated in the housing. Sensors without housing: Casing similar to TO case, pressure is applied through a central pressure fitting. Of the available soldering pins the following are needed: Pin 6 Output voltage UA, Pin 7 Ground, Pin 8 +5 V.

Pressure sensors For pressures up to 1800 bar (180 Mpa)

P Ratiometric signal evaluation (referred to supply voltage). P Self-monitoring of offset and sensitivity. P Protection against polarity reversal, overvoltage, and short circuit of output to supply voltage or ground. P High level of compatibility with media since this only comes into contact with stainless steel. P Resistant to brake fluids, mineral oils, water, and air. Application Pressure sensors of this type are used to measure the pressures in automotive braking systems, or in the fuel-distributor rail of a gasoline direct-injection engine, or in a diesel engine with Common Rail injection.

Only for 0 265 005 303 This sensor differs from conventional sensors due to the following diagnostic functions: – Offset errors – Amplification errors can be detected by comparing two signal paths in the sensor. Storage conditions Temperature range –30...+60 °C Relative air humidity 0...80 % Maximum storage period 5 years Through compliance with the above storage conditions, it is ensured that the sensor functions remain unchanged. If the maximum storage conditions are exceeded, the sensors should no longer be used. Explanation of symbols Output voltage UA Supply voltage UV bar Pressure

Characteristic curve. UA = (0.8 · p / pNom. + 0.1)UV

V 4.5 4 Output voltage UA

Design and function Pressure measurement results from the bending of a steel diaphragm on which are located polysilicon strain-gauge elements. These are connected in the form of a Wheatstone bridge. This permits high signal utilisation and good temperature compensation. The measurement signal is amplified in an evaluation IC and corrected with respect to offset and sensitivity. At this point, temperature compensation again takes place so that the calibrated unit comprising measuring cell and ASIC only has a very low temperature-dependence level. Part of the evaluation IC is applied for a diagnostic function which can detect the following potential defects: – Fracture of a bonding wire to the measuring cell. – Fracture anywhere on any of the signal lines. – Fracture of the bridge supply and ground.

Design and function NTC sensor: The sensing element of an NTC temperature sensor (NTC = Negative Temperature Coefficient), is a resistor comprised of metal oxides and oxidized mixed crystals. This mixture is produced by sintering and pressing with the addition of binding agents. For automotive applications, NTC resistors are enclosed in a protective sheath. If NTC resistors are exposed to external heat, their resistance drops drastically and, provided the supply voltage remains constant, their input current climbs rapidly. This property can be utilised for temperature measurement. NTC resistors are suitable for an extremely wide range of ambient conditions, and with them it is possible to measure a wide range of temperatures. Installation instructions Installation is to be such that the front part of the sensing element is directly exposed to the air flow.

Design and function The sensor element comprises a ceramic substrate containing the following thick-film resistors which have been applied using silk-screen printing techniques: Air-temperature-sensor resistor Rϑ, heater resistor RH, sensor resistor RS, and trimmer resistor R1. The heater resistor RH maintains the platinum metallic-film resistor RS at a constant temperature above that of the incoming air. The two resistors are in close thermal contact. The temperature of the incoming air influences the resistor Rϑ with which the trimmer resistor R1 is connected in series. Throughout the complete operating-temperature range it compensates for the bridge circuit’s temperature sensitivity. Together with R2 and Rϑ, R1 forms one arm of the bridge circuit, while the auxiliary resistor R3 and sensor resistor RS form the other arm. The difference in voltage between the two arms is tapped off at the bridge diagonal and used as the measurement signal. The evaluation circuit is contained on a second thick-film substrate. Both hybrids are integrated in the plastic housing of the plug-in sensor. The hot-film air-mass meter is a thermal flowmeter. The film resistors on the ceramic substrate are exposed to the air mass under measurement. For reasons associated with flow, this sensor is far less sensitive to contamination than, for example, a hot-wire air-mass meter, and there is no need for the ECU to incorporate a self-cleaning burn-off function.
