This compact calibrator is for a piezoelectric type acceleration pickup which has been widely used for measuring vibration.
Since an exciter, a sensor amplifier and a display are integrated on the unit together, direct reading of sensitivity is possible when sensor outputs are directly input. The calibrator excites the sensor at a frequency of 159 Hz and acceleration of 10 m/s2 rms, and sensor outputs can be used as calibration signals for a vibration measuring system.

Features

  • Suitable for acceleration pickup of both charge output and built-in amplifier types.

  • Adoption of digital indicator allows direct reading of sensitivity.

  • Operates on dry battery for as long as 20 hours.

  • A carrying case is provided to make carrying easy.
