Calibrate Vibration Aaccelerometer Velocity and Proximity Transducer Vibration Calibrator
HG5026 Vibration Calibrator can be used to calibrate vibration accelerometer, velocity and proximity transducer and also a vibration measuring instrument. Standard sine signal vibration at any frequency from 1 to 1280 Hz can be defined in the 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. HG5026 Vibration Calibrator combines sine signal generator, power amplifier, standard transducer and the vibration head in one and features a smaller volume, high accuracy and easy operation. It can be used either in laboratory or on site.

Maximum vibration amplitude and maximum sensor weight
Because of the vibration head used in HG5026 Vibration Calibrator is rather small, during the calibration of transducers of different weight under different frequencies the output amplitude of the calibrator is also different. Maximum vibration amplitude and maximum weight are related to the maximum acceleration, maximum velocity and maximum displacement generated by the calibrator under certain frequency and with a certainweight of thetransducer to be calibrated. The specific figures can be seen in the following table.

*With higher frequency the value of the displacement of vibration is very small so there will be no vibration signal output from the calibrator.
