High-Sensitivity, Single Axis K-Beam® MEMS Capacitive Accelerometer
A new series of single axis MEMS (Micro-Electro-Mechanical Systems) capacitive accelerometers has been launched by Kistler Instruments for use where high-precision, low-frequency measurements and compact, robust construction are absolute requirements. The new accelerometers use Kistler's K-Beam technology to deliver precision, sensitivity and low noise characteristics for a range of automotive, aerospace, OEM, R&D and general laboratory test applications.
The Type 8315A series is made up of six models with measurement rages from ±2 g to ±200 g with a frequency response of zero to 1,000 Hz (5%) in a compact design having a footprint of only 25.4 mm. The MEMS variable capacitance sensing element consists of a small inertial mass located between two parallel plates. Deflection of the inertial mass under acceleration causes a proportional change in the capacitance of the sensing element. An integrated analogue signal conditioner converts this change to a proportional voltage output. The excellent thermal stability of the MEMS construction provides reliable performance within the wide operating temperature range of -55 to +125 degrees Celsius.
Three housings are available; one lightweight, environmentally sealed, hard anodized with integral ground isolation and two welded titanium housings with either an industry standard 4-pin connector or a Teflon® coated cable.
Typical applications include low-frequency aerospace ground vibration testing, wind tunnel vibration analysis, structural dynamics, automotive testing, vehicle road testing and ride assessments and human motion studies.
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.
