Thank you for choosing a vibration calibrator from Monitran.

• Easy and simple calibration of vibration metering, recording and control equip­ment

• Regular checks of such devices and
installations

• Fault finding

• Handy and robust battery device for laboratory and field use

• Load-independent vibration magnitude with an RMS of

- 10 m/s² vibration acceleration

- 10 mm/s vibration velocity

- 10 µm vibration displacement

• Quartz stabilized vibration frequency of 159.15 Hz (radian frequency 1000/s)

• Suitable for test objects weighing up to 600g

The vibration calibrator VC20 generates mechanical vibrations with quartz stabil­ized frequency and precisely controlled magnitude. Vibration sensors, including
connected cables, signal conditioners and readout instruments can be calibrated in
acceleration, velocity or displacement units.

A reference accelerometer inside the shaker head and a control circuit keep the vi­bration level constant and independent of the weight of the attached measuring ob­ject. A display indicates the error in percent. There is an acoustical warning when
the error limit is exceeded.

Because of its internal rechargeable battery, the VC20 is well suited for mobile ap­plications. The instrument features an automatic switch-off function preventing acci­dental discharging. The display indicates the battery charging condition. The unit
comes with an external mains supply for charging.

The supplied plastic carrying case allows convenient handling and safe transport.
