PCE-VC20 is a vibration calibrator used to calibrate vibration sensors, meters, analyzers and testers. Suitable for calibrating equipment weighing up to 600 g (1.32 lb), this vibration calibrator generates mechanical vibrations with a quartz-stabilized vibration frequency of 159.15 Hz (radian frequency 1000/s).

PCE-VC20 features load-independent vibration magnitude with an RMS of:
- 10 m/s² vibration acceleration
- 10 mm/s vibration velocity
- 10 µm vibration displacement

A control circuit and reference accelerometer inside the excitation or shaker head work in tandem to keep the vibration level constant. A display indicates the error percentage (%). The error % represents the deviation of the target value from the measured amplitude. In settled conditions, the display should come close to 0.0 % if the calibration is correct. If the error % is above 3 %, the device sounds an audible alert to indicate that the error limit is exceeded. In addition, the vibration calibrator switches off automatically in case of overload. Sensors can be connected via magnet or thread. A thread adapter is included in the delivery contents to accommodate M3, M5, M8, 1/4"-28 and UNF 10-32 threads.

The vibration calibrator has many versatile features for field and laboratory use, including a built-in rechargeable battery, battery-saving automatic power-off function, battery charge indicator and AC power adapter for charging. In addition, the supplied carrying case allows for convenient handling and safe transport.

GJX-6 Vibration Calibrator

 Can be used to calibrate vibration accelerometer, velocity and proximity transducer and also a vibration measuring instruments. Standard sine signal vibration at any frequency from 10 to 1280 Hz can be defined in the calibrator. The amplitude of the acceleration, velocity and displacement, can be defined through potentiometers and shown on digital displays. Either horizontal or vertical vibration can be generated. GJX-6 combines sine signal generator, power amplifier, standard transducer, vibration meter 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.
