Kistler has introduced the Type 8781A50, a PiezoStar (IEPE-type) piezoelectric accelerometer with center hole mounting, expressly designed to provide vibration measurements across three orthogonal axes, in support of aerospace and automotive NVH and other testing environments characterized by rapid temperature fluctuations.

The Type 8781A50 features a 50 g measurement range and a 100 mV/g sensitivity. Its design incorporates Kistler’s own proprietary PiezoStar shear element crystal technology, along with high-gain integral hybrid microelectronics, for a transducer that offers a broad frequency response and sensitivity variation over an operating temperature range of -54 °C to +120 °C (-65 °F to +248 °F). Sensing elements are housed in a ground isolated, welded hermetic titanium package.

Models designated with optional “T” suffix incorporate Transducer Electronic Data Sheet (TEDS) capabilities per IEEE 1451.4-2004. Units are intended for up to 5000 g pk shock and are powered by a 20-30 VDC or 2-18 mA constant current supply.
 
Kistler recommends this accelerometer for use in vehicle powertrain and off-highway NVH investigations. It can also be used to perform joint measurements between aggregates and the car body, as well as measurements on the engine itself, where wider temperature fluctuations are most commonly experienced. Additionally, the Kistler Type 8781A50 can be used for structural analysis and the general vibration testing of automotive subsystems, as well as full vehicle testing.
