Acceleration Pickup Calibrator

VX-1100A

VX-1100 is for a piezoelectric type accelerometer which is widely used for measuring vibration. This compact calibrator is effective for checking operation(sensitivity) sensors before measurement to acquire accurate data.

Built-in sensor amplifier and display in one unit allows direct reading of the sensitivity. This calibrator excites the sensor at a frequency of 159 Hz and acceleration of 10 m/s² rms, and the sensor outputs can be used as calibration signals for a vibration measuring system.

Feature

Standalone unit having three functions of an exciter, sensor amplifier and display
Can be used for accelerometers of both charge outputtype and built-in amplifier type.
Required amplifier can be selected by switching.(0.5 mA, 2 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.
