PiezoStar triaxial IEPE piezoelectric accelerometer

  • 23-Aug-2011 01:10 EDT


Kistler's PiezoStar (IEPE-type) piezoelectric accelerometer with center hole mounting is designed to provide vibration measurements across three orthogonal axes in support of automotive and aerospace noise, vibration, and harshness (NVH) and other testing environments characterized by rapid temperature fluctuations. With a 50 g measurement range and a 100 mV/g sensitivity, the Type 8781A50’s rugged design incorporates Kistler’s proprietary PiezoStar shear element crystal technology, along with high-gain integral hybrid microelectronics, for a transducer that offers a broad frequency response. The accelerometer also features low sensitivity variation over an operating temperature range of -54 to +120°C (-65 to +248°F). The device 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.
