Product Introduction
GJX-3 Vibration Calibrator
This Vibration Calibrator can be used to calibrate vibration accelerometer, velocity and proximity transducer and also a vibration measuring instruments. Standard sine signals at frequency 10, 20, 40, 80, 160, 320, 640 and 1280 Hz can be generated from this Vibration Calibrator. The amplitude of the, acceleration, velocity and displacement, can be defined through potentiometers and shown on digital displays. Either horizontal or vertical vibration can be generated by this Vibration Calibrator.
GJX-3 Vibration Calibrator combines sine signal generator, power amplifier, standard transducer and a shaker in one and features a small volume, high accuracy and easy operation. It can be used either in laboratory or on site.
