Nova Instruments LLC Acquires Sherborne Sensors Ltd.
Nova Instruments LLC, Woburn, MA is pleased to announce the acquisition of Sherborne Sensors Ltd on September 28, 2012. Headquartered in Basingstoke, Hampshire, UK, Sherborne Sensors designs, manufactures, and sells precision inclinometers, accelerometers and force transducers. "Sherborne’s inertial and force transducers have established themselves as benchmark products in terms of quality and performance over the last decade and will extend the footprint of Nova Instruments, our Test and Measurement platform, while sharing common technologies and end users with Nova Metrix, our sister company, that is dedicated to geotechnical applications," commented Jim Barbookles, Chairman and CEO of Nova Instruments LLC. "With Sherborne Sensors, Nova Instruments will be able to increase its offerings to customers who need to ensure design concepts deliver performance requirements within a broad range of industries including Aerospace, Oil & Gas and Automotive," said Jean-Marc Muller, President of Nova Instruments.
Introducing the A700 range of Solid State Accelerometers
This month we are pleased to highlight our A700 series of Solid State Accelerometers. These sensors employ Advanced MEMs technology to offer precision measurement of acceleration in single or dual axis applications, with positive mechanical stops conferring excellent shock resistance. The A700 Series accelerometers can be utilized in a wide range of acceleration sensing projects, including space constrained applications. These low mass products are ideal for the analysis of light weight structures where mass loading effects are a concern. The -0101 version incorporates a temperature sensor enabling each accelerometer to be individually characterized for performance over its compensated temperature range. A data sheet containing the characteristic output equation is supplied with each sensor, enabling accuracies of better than ±1 milli g over a temperature range of -18 to +70°C. By entering the equation coefficients into the host operating software, cost-effective high accuracy acceleration sensing can be achieved. Designed for operation from an unregulated DC power source, the A700 series are packaged in a miniature, robust aluminum alloy housing with an integral shielded cable connection. The cable may, as an option, be fitted with an electrical connector. The A700 Series Accelerometers form part of a wide range of high precision accelerometersdesigned to measure linear acceleration and deceleration with the highest levels of accuracy and reliability, and suitable for use in demanding aerospace, aviation, military and industrial applications.
Mike Might Know: How can sensors help to improve passenger comfort at sea? The use of accelerometers in motion control systems has become an important area of development in marine applications. This is in part due to the fast-growing market for offshore wind farm support vessels. Designed to transport engineers to and from offshore wind farms, support vessels are often relatively small and in many cases traverse rough waters. The engineers need to arrive in safety and also in a fit state to commence work. In a perfect journey, as the wave builds, the vessel climbs to the crest and declines the other side. Unfortunately, in many instances the wave either breaks early or breaks late, forcing the hull of the vessel out of the water. When it re-engages with the water, the slapping motion generates a sudden change in acceleration of the vessel and all within.
This is exactly the type of motion an accelerometer is designed to measure. When the slap occurs, the accelerometer output can be monitored, and translated into the level of passenger safety/discomfort. Within a motion control system, it would be possible to employ the real-time data provided by an accelerometer to decide whether to increase or decrease the speed of the vessel. However, it is a lot easier to control the rocking motion of a vessel than the slapping that results from hitting the wrong part of a wave. Gathering critical data via the use of accelerometers not only makes it possible to put some relative measures on the safety and comfort of passengers, but also leads to the development of technology and improvements in hull design. More details on the Sherborne Sensors range of accelerometers can be found on our website.
