Kistler Introduces Triaxial K-Beam MEMS Capacitive Accelerometer Family

By DE Editors

Kistler North America has announced the launch of the Type 8395A,  a miniature, cube-shaped, high-sensitivity, low-noise triaxial MEMS capacitive accelerometer series, incorporating Kistler’s own K-Beam technology. The Type 8395A is designed to simultaneously measure acceleration and low-frequency vibration in three mutually perpendicular axes (x, y and z) within a variety of automotive, aerospace, OEM, R&D and general laboratory test applications.

  The Kistler Type 8395A series is available in six different models, with measurement ranges from ±2 g to ±200 g and a frequency response of 0 to 1000 Hz (5%). The compact design provides a 0.85-in. (21.6 mm) cube footprint and incorporates a MEMS variable capacitance sensing element, consisting of a small inertial mass and flexure element sandwiched between two parallel plates. As the mass deflects under acceleration, the capacitance between the element and plates changes, which is converted to a proportional voltage by the internal analog signal conditioner.

  The output signal format of the Type 8395A series is bipolar at 0±4 V and provides a high-sensitivity,  low-noise signal, which is compatible with a variety of data acquisition or readout devices.  The accelerometer is shock rated to 6,000 g pk. Sensing elements and integral electronics are housed within a lightweight, welded titanium housing with a miniature circular 9-pin connector.

  The Kistler Type 8395A triaxial capacitive MEMS accelerometer series offers an operating temperature range of -65°F to 250°F (-55°C to +125°C). It is powered by a single wide range supply between +6 and +50 VDC and has an internal voltage regulator. In the event that external temperature compensation is desired, a temperature output is provided,  in addition to the output signals.
