Vibration Accelerometer Calibration

Calibrate and verify your accelerometers quickly. In your own lab.

Our Accelerometer Calibration & Verification package(VR9106) offers an automatic and accurate calibration of IEPE and charge mode piezoelectric accelerometers or transducers. Our test package can also write to TEDS capable sensors. Requires 2-channel VR9500 controller, SineVIEW, vibration exciter and a reference sensor (also available as a complete package).

Also available as a complete package including shaker, 2-channel controller, reference sensor and software for a complete turn-key system.



Principle Operation

To calibrate a vibration accelerometer is to accurately determine its sensitivity (in mV/g or pC/g) at various frequencies of interest. The ISA approved back-to-back comparison method is probably the most convenient and least expensive technique. back to back accelerometerAt Vibration Research the back-to-back calibration involves coupling the test accelerometer directly to a (NIST) traceable double-ended calibration standard accelerometer and driving the coupled pair with a vibration exciter at various frequencies and acceleration (g) levels. The assumption here is that since the accelerometers are tightly coupled together, both will experience exactly the same motion, thus the calibration of the back-to-back standard accelerometer can be precisely "transferred" to the test accelerometer.
