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) |
| 10Hz | 2.5 | 28 | 1300 | 3.5 | 40 | 1800 | 4 | 45 | 2000 |
| 20Hz | 15 | 85 | 1900 | 10 | 60 | 1300 | 5 | 28 | 640 |
| 40Hz | 60 | 170 | 2000 | 35 | 100 | 1100 | 12 | 35 | 380 |
| 80Hz | 100 | 141 | 800 | 40 | 60 | 320 | 14 | 20 | 110 |
| 160Hz | 75 | 53 | 150 | 35 | 25 | 70 | 12 | 8.5 | 24 |
| 320Hz | 50 | 18 | 25 | 30 | 10 | 15 | 10 | 3.5 | 5 |
| 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.
