VC120
The VC120 is a stand-alone calibration device with:
- Piezoelectric vibration exciter and power amplifier
- Frequency from 70 Hz to 10 000 Hz
- Built-in reference accelerometer
- Directly connect output signal from accelerometer (Charge, IEPE (ICP), Voltage)
- Sensitivity display with physical units
- Stand alone or PC control by USB
- Rechargeable battery
The VC120 works at a constant amplitude of 1 m/s² (RMS). The frequency is adjustable in fine intervals from 70 Hz to 10 kHz. It can be adjusted by a shuttle wheel. Alternatively, all settings can be made by the supplied PC software via a USB interface. Thus the VC120 can also measure frequency sweep diagrams. A backlit LCD shows the adjusted frequency and the measured transducer sensitivity either in metric or in imperial units. The built-in NiMH accumulator lasts for 2 to 4 hours of calibration. In spite of its compact design the instrument is portable and features a variety of functions, which are known only from more expensive systems.
Metra’s vibration calibrators are supplied with a traceable calibration certificate. DAkkS accreditation can be offered on request.
