Kistler Portable Shaker Accelerometer Calibrator Type 8921
The Kistler Portable Shaker Accelerometer Calibrator Type 8921 is a small, self contained, battery powered vibration exciter specifically designed to verify/calibrate the sensitivity of accelerometers in a field environment.
The Kistler Portable Shaker Accelerometer Calibrator Type 8921 provides an accurate controlled vibration level to verify sensitivity of vibration sensors or the complete measuring system. The internal control and excitation system provides a constant, exact frequency while a closed loop control maintains a constant amplitude independent of the mass of the test article.
Should the test article exceed the capacity of the shaker, the unit provides an audible and visual warning to the operating. A self contained, rechargeable battery can power the shaker up to approximately three hours between recharging.
