ServoK-Beam High Sensitivity Capacitive Accelerometer for measuring low level acceleration
New from Kistler Instruments (www.kistler.co.uk), is a single axis, high sensitivity, capacitive accelerometer for measuring static acceleration or low-level, low-frequency vibration.
The new ServoK-Beam accelerometer has high resolution, excellent frequency response and insensitivity to thermal transients and transverse acceleration making it ideal for a wide range of applications from modal analysis of large structures and vehicle dynamics to measuring seismic effects on structures during earthquakes and aerospace ground testing.
The measurement range of ±3 g, wide static and dynamic frequency response from zero to 500 Hz and ultra-low noise of 4 µgrms below 100 Hz are combined with sensitivity of 1,200 mV/g, high immunity to thermal transients 1,500 gpk shock rating and low transverse acceleration. The ServoK-Beam is a three terminal, variable capacitance sensor, made by a bulk Micro Electro-Mechanical System (MEMS) process. The sensing element and conditioning electronics are integrated into an hermetically sealed titanium housing with a mass of 95 grams. A hard anodized housing provides ground isolation and the unit is powered by a bipolar supply between ±6 and ±12 V DC.
Established in Winterthur (Switzerland) in 1957, the Kistler Group now has a worldwide presence with 25 group companies and 30 distributors ensuring prompt, local application support and short delivery times. With a staff of more than 1050, the Kistler Group is one of the world's leading providers of dynamic measuring instrumentation with a turnover of 210 million Swiss Francs (GBP 145M) in the 2010 financial year.
Kistler's core competence is the development, production and use of sensors for measuring pressure, force and acceleration. Kistler's know-how and electronic systems can be used to prepare measuring signals for use in analysing physical processes, controlling and optimising industrial processes, improving product quality in manufacturing and improving performance in sports and rehabilitation.
Kistler offers a comprehensive range of sensors and systems for engine development, automotive engineering, plastics and metal processing, installation technology and biomechanics.
Heavy investment in research and development, 15% of staff worldwide are engaged in research and development, has generated a number of innovations using piezoelectric, piezoresistive and capacitive techniques to provide solutions to numerous force, pressure and acceleration measuring problems. These innovations include the world's first commercial quartz sensor, two-wire constant current technology to integrate sensors with microelectronic circuitry, high-temperature pressure sensors for use up to 400 Deg C and three-component force measuring sensors.
