vibration measuring instrument

 Bearing vibration measuring instrument is generally composed of driving device, sensor, amplifier, filter, measurement display and self-calibration system. The driving device drives the inner ring and rolling elements of the bearing to be tested. The radial vibration acceleration signal generated by the bearing at this time is picked up by a piezoelectric acceleration sensor and converted into a charge signal to be amplified by an amplifier and filtered by a band-pass filter It is sent to the measurement display circuit, and the acceleration decibel value is displayed through the RMS meter and the PEAK meter, and the performance of the bearing is characterized through various forms such as oscilloscope and loudspeaker.http://www.zysbearing.com/bearing-parts-measuring-instruments/s95-single-ball-vibration-measuring-instrument.html
