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.
