Digital Vibration Calibrator Calibrate Vibration Meter Vibration Analyzer Vibration Tester VMC-5000

Application for Vibration Calibrator:
1.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
2.Can be generated from the calibrator the amplitude of the acceleration, velocity and displacement
3.Can be defined through potentiometers and shown on digital displays. Either horizontal or vertical vibration can be generated.
4.VMC-5000 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.

Maximum vibration amplitude and maximum load:
Because of the vibrostand used in VMC-5000 Vibration Calibrator is rather small, during the calibration of transducers of different weight under different frequencies the output amplitude of the calibrators are also different. Maximum vibration amplitude and maximum load are related to the maximum acceleration. Maximum velocity and maximum displacement output generated from the calibrator under a certain frequency and with a certain weight of the transducer to be calibrated. The specific figures can be seen in the following table.


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