The HVC-500 is a small, self-contained handheld shaker designed for quick and easy checking of accelerometers,vibration monitoring & protection systems and data recorders
Description
Model HVC-500 permits accurate adjustment of measuring instrumentation at a standard acceleration level of 10 m/s² (0 –150 g load). The reference signal may additionally be used for velocity and displacement calibration, at 10 mm/s and 10 µm, respectively.
The calibrator is as an electromagnetic exciter driven by a crystal oscillator at a frequency of 159.15 Hz withservo feedback via a small accelerometer on the underside of the vibration mandrel which is used to maintain a constant and accurate vibration level independent of the mass of the transducer under test.
