Vibration Calibrator VC-01A

Vibration calibrator VC-01A is a small, portable calibration instrument. It provides a stable vibration reference source that can conveniently and accurately calibrate accelerometers, velocity sensors and displacement sensors, and also test the measurement system consisting of sensors to determine whether the sensors and the entire measurement system are working properly. The instrument is small, lightweight and easy to use.

VC-01A has a sinusoidal signal generator, a power amplifier, an electrodynamic shaker and a highly stable standard reference accelerometer that provides a high-quality closed-loop vibration reference source.

When the device is in operation, the internal signal source generates a standard sinusoidal signal at 80 Hz, 159.2 Hz or 1 kHz, which is driven by a power amplifier to drive the shaker so that the transducer under test is at a standard acceleration level of 0.98, 4.91, 9.81 g rms. 

The reference signal can also be used for velocity and displacement, at 0.98, 4.91, 9.81 mm/s rms and 0.98, 4.91, 9.81 μm rms respectively.

Principle of operation:

The VC-01A portable vibration calibrator utilizes a built-in standard accelerometer and an external probe mounted back-to-back to test by the comparison method, using closed-loop control to provide a highly stable vibration reference source.

Vibration Calibrator VC-01

The VC-01 vibration calibrator is a small and light hand-held calibrator for quick checking of acceleration and vibration sensors.

With the VC-01 vibration calibrator, sensors up to a total weight of 70g can be checked for function and accuracy very easily.

Regardless of the mass of the test object, the acceleration at the vibrating table of the calibrator is kept constant via an integrated reference sensor.

The signal emitted by the device under test can be measured using an RMS voltmeter, an oscilloscope or an FFT analyzer.
