loopfrequencysignal

Vibration Calibrating System Application • Rapid and easy calibration and fault detection of vibration sensors and instruments • Determination of amplitude response Properties • Self-contained calibration system • Test amplitude of 1 m/s² rms • Vibration frequency from 70 Hz to 10 kHz • Suitable for test objects weighing up to 400 gr. • Internal signal conditioner for charge, IEPE and voltage • Traceable to PTB standard • USB interface for PC controlled calibration • PC software for calibration and display with sensor data base included • Customer software control by simple ASCII commands • Mains buffered NiMH battery for desktop and field use • Unequalled price-performance ratio 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.
