MOTOR ECG VIBRATION ANALYZER-KOKUSAI MV-20, MV-20D

Producer: EGC-KOKUSAI

Categories: Vibration analysis system, Decibel, Engine vibration meter

ECG-KOKUSAI Japan MV-20 / MV-20D Motor Vibration Monitor.
A very small audible vibration during operation can indicate a major defect in a small precision motor. Audible vibration is often detected by using a sounding stick held to the ear of an inspector to assess whether the motor should be scrapped or by listening to its sound during operation.
This method gives different assessments depending on the inspector and cannot be automated. With this device, a highly sensitive acceleration type detector is applied to the bearing area of the motor to directly eliminate the audible vibration.
The resulting measurement is not affected by environmental noise and can perform absolute and precise measurements. It is also possible to automatically judge whether to reject or pass the motor by incorporating an optional comparator.

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 detect 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.
