Digital Vibration Calibrator, calibrate vibration accelerometer,

velocity, transducer VMC-6000

Application for Vibration Calibrator:

1.Can be used to calibrate vibration accelerometer, velocity and proximity transducer.

2.It can also be used to calibrate vibration monitoring / measuring instruments or

data acquisition / data collector devices. Standard sine signals at continually

varying frequency from 10, to 1280 Hz can be generated from the calibrator.

3.The amplitude of the acceleration, velocity and displacement can be defined and

shown on LCD digital panel. Either horizontal or vertical vibration can be generated.

4.VMC-6000 combines sine signal generator, power amplifier, standard transducer

and a shaker in one and features a small volume, high accuracy and easy

operation. Use either in lab or on site.

Proximity probe linearity

Probe: 5mm and 8mm and 11mm probes Range: 0~2.0mm

Display: 3 ¹/₂ digit display for acceleration, velocity or displacement

Maximum vibration amplitude and maximum load:

Because of the vibrostand used in VMC-6000 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.

Wt Freq	<100g			<250g			<650g
	a(m/S2)	v(mm/S)	d(μm)	a(m/S2)	v(mm/S)	d(μm)	a(m/S2)	v(mm/S)	d(μm)

640Hz	30	5	3	20	3.5	2	6	1	*
1280Hz	23	2	*	10	0.9	*	5	0.4	*

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.
