Kistler has introduced its K-Beam MEMS capacitive accelerometer family. The K-Beam family is designed to support single axis and triaxial measurement requirements within automotive, aerospace, civil engineering, original equipment manufacturer (OEM), R&D and in-laboratory test applications, particularly where use of an instrument-grade accelerometer for high-precision, low-frequency measurements is required.
The K-Beam family is offered in ranges from ±2 g to ±200 g and with frequency response from DC to 1000 Hz (5%). Accelerometers are available in four different models of either single axis (Type 8315A) or triaxial (Type 8395A) versions and incorporate a MEMS variable capacitance sensing element. All units are designed for an operating temperature range of -65 °F to +250 °F (-55 °C to +125 °C), with 6,000 g pk shock survivability.
The Type 8315A single axis version features a 1-inch (25.4 mm) footprint and is powered by a single wide range supply between +6 and +50 VDC. The six available Type 8315A models are offered with three different housing and electrical interface options (AC, TA, TB), which determine available output signal formats. The AC option features environmental sealing, integral ground isolation, epoxy seal and integral PVC cable, with a maximum operating temperature of +185 °F (+85 °C). Available AC option output signal formats are bipolar at 0 ±4V; single ended 2.5V ±2V; or differential 0 ±8V.
Series TA and TB options offer a choice of 4-pin,-28 connector or integral Teflon jacketed cable with integral ground isolation. Temperature output is also provided, should external temperature compensation be desired. The TA and TB options have an operating temperature range of -65 °F to +250 °F (-55 °C to +125 °C).
The Type 8395A triaxial version is designed to simultaneously measure acceleration and low-frequency vibration in three mutually perpendicular axes (x, y and z). The output format of the Type 8395A series is bipolar at 0 ±4V and is compatible with a wide variety of data acquisition or readout devices. Sensing elements and integral electronics come with a specially designed miniature circular 9-pin connector. It is powered by a single wide range supply between +6 and +50 VDC.
