PCE-VC21 is a portable shaker 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 adjustable quartz-stabilized vibration frequencies between 15.92 and 1280 Hz and adjustable vibration amplitudes between 1 m/s² and 20 m/s².
These adjustable vibration frequencies and amplitudes allow for the calibration of low-frequency vibration sensors such as those in structural vibration meters in line with DIN 4150-3 and in human vibration meters according to ISO 8041.
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.
