Sensitivity Calibrator for Piezoelectric Accelerometers



Photo (VX-1100 Acceleration Pickup Calibrator)




Piezoelectric accelerometers are widely used in vibration measurements. In order to obtain correct data, it is necessary to check the operation (sensitivity) of sensor before use.

The VX-1100A is a simple type sensitivity calibrator that is designed for use with piezoelectric accelerometers. This calibrator has functions as exciter, sensor amplifier, and display unit so the sensitivity value can be read directly on the display simply by connecting an accelerometer to the VX-1100A.

The VX-1100A excites an accelerometer with sine wave of 159.2 Hz and 10 m/s2 (rms) so that the output can be used as calibration signal for vibration measurement system.


  • Standalone unit having three functions of an exciter, sensor amplifier and display
  • Can be used for accelerometers of both charge output type and built-in amplifier type.
    Required amplifier can be selected by switching.(2.0 mA, 4.0 mA, or charge amplifier)
  • Digital display allows direct reading of sensitivity.
  • Compact and light weight
  • Long time continuous operation(approx. 8 hours)
  • Accessories necessary for measurement are equipped as standard.
  • Carrying case is provided for easy carrying.
