Vibration calibrator enables accurate adjustment of measuring instrumentation and transducers, such as accelerometers at a standard acceleration level of 10 ms–2 (0 – 70 g load). The reference signal may additionally be used for velocity and displacement calibration, at 10 mms–1 and 10 µm respectively.

Using the vibration calibrator is very straightforward. Simply attach a transducer to the calibrator table using a 10–32 UNF Steel Stud (YQ-2962), and that's it.

The calibrator embodies an electromagnetic exciter driven by a crystal oscillator at a frequency of 159.15 Hz (1000 rad s–1). Servo feedback via a small accelerometer on the underside of the vibration table is used to maintain a constant and accurate vibration level - independent of the mass of the transducer under test.
