Présentation

The VC21 portable shaker is designed for quick and easy verification and calibration of accelerometers. The VC21 can generate 7 selectable vibration frequencies: 15.92; 40; 80; 159.2; 320; 640; 1280 Hz. Extremely simple to use, the VC21 comprises just a few buttons on the shaker for selecting signal frequency and amplitude. A bright OLED display shows frequency and amplitude, amplitude error in percent and battery status. The VC21 incorporates an amplitude and frequency regulation stage, making them independent of the mass of the accelerometer being evaluated. Weighing just 2.2 kg and with its built-in battery (5h autonomy), the VC21 vibrating pot can be used both in the lab and in the field. Optional, part no. VC21D: Removable clamp for dynamic calibration of non-contact displacement transducers (inductive / eddy current) at 159.2 Hz, with threaded adapters for all common transducer types (part no. VC21D).
