Vibration calibrator HVC-500

accelerationhand-held

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 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. Switchable 1g RMS Acceleration output Drives vibration transducers which weigh up to 150g Operates at 159.2 Hz (1000 rad/sec) Internal Battery CE compliant Provides 80 to 1600 calibration cycles, depending on accelerometer weight and is powered by a self contained battery pack. The automatic shut off after a 1.75 minute cycle can be overridden by a switch to provide continuous operation when required. Protected against overload by mechanical stops
