Metra is a leading manufacturer of vibration sources for the calibration of accelerometers, velocity and displacement sensors. Metra’s vibration calibrators have some unique features such as a very high payload and variable vibration frequencies.
Quick and simple calibration and fault detection of sensors and measuring chains for acceleration, velocity and displacement
Load independent vibration magnitude
Vibration magnitude of 10 m/s² (VC20) or selectable in 5 steps from 1 to 20 m/s² (VC21)
Quartz stabilized vibration frequency of 159.2 Hz (VC20) or selectable in 7 steps from 15.92 Hz to 1280 Hz (VC21)
Suitable for the calibration of whole-body human vibration meters to ISO 8041 and building vibration meters to DIN 4150-3
