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.
