Motor vibrophonic monitor

Model: MV-20 / MV-20D

The acoustic vibration is detected directly by an acceleration detector.

Unusual sound and vibration testing machine ECG-KOKUSAI Motor vibrophonic monitor MV-20/ MV-20D A very small acoustic vibration during operation can indicate a major defect in a small-sized precision motor. The acoustic vibration is normally detected using a sounding bar applied to the ear of an inspector who judges whether to reject or pass a motor by listening to its sound during operation. This method produces different judgments according to each individual inspector, and automation is not possible. With this unit, a highly sensitive acceleration-type detector is applied to the bearing area of a motor, to directly defect the acoustic vibration. The resultant measurement is not influenced by environmental noise, and an absolute and accurate measurement can be made. Automatic judgment of whether to reject or pass a motor is also possible by incorporating an optional comparator. Features • The acoustic vibration is detected directly by an acceleration detector. • Consequently, the measurement is not affected by environmental noise. • The result of the measurement is displayed on a meter and sound signals are reproduced using a wide range loud speaker. • A frequency filter is incorporated to allow selection between full, high and low range frequencies. • Incorporating a comparator makes automatic judgment of reject or pass. Function ♦  By using the USB communication function of MV-20D, the vibration waveform data can be output to an external host. ♦ By RS-232C control, measurement condition settings, comparator settings, and measured values can be obtained. ♦ With 5-step measurement range and 3-step frequency band filter, you can concentrate on listening to the sound source.  With the comparator function, you can judge OK/NG. ♦  Mute function allows adjustment of measurement timing.
