Product Description

The calibrator VC120 is a piezo mechanic exciter suitable for testing and calibration of sensors and instruments in units of acceleration, velocity and displacement. Its adjustable vibration frequency allows verifying transducer sensitivity at individual frequencies according to your sensor application. Amplitude response can be measured as well.

By means of an internal reference loop the vibration level is measured and controlled. The FFT spectrum of the vibration signal is permanently monitored and possible distortion compensated using Metra's unique ACHD technique.

The VC120 features a signal conditioning channel for the connection of sensors and measuring chains. It is suitable for sensors with charge, voltage and IEPE compatible outputs. The calibrator calculates the rms of the input signal. Measurement results with the corresponding units and all important settings are clearly shown on an LCD graphics display. Thus the VC120 contains all what is needed for the calibration of sensors and measuring chains.

Measured data can be processed, displayed and stored by the included PC software. For that purpose the VC120 provides an USB interface. The interface can also be used in virtual COM port mode for control by your own sotware using simple ASCII commands.

The instrument is supplied with a factory calibration certificate which is traceable to a primary reference standard of PhysikalischTechnische Bundesanstalt (PTB).
