for bearings
Sonar device FAG sound detector is used to check the noise of the rolling bearing in a quick and easy way. The changes in the noise may be due to the formation of pitting or wear or distortion of the bearing, which can be detected with regular inspections at an early stage.
In this way, one can prevent significant machine damages and unpredictable operational blocks. This device can be used in the same way as a doctor uses his stethoscope. In order to provide insulation against the background noise, the earplugs are placed in the ear canals.
By holding the insulated grip between the thumb and index finger, the sensor is placed tightly on the place that needs to be measured. In case of any noise is heard, the sensor is moved in that place till the noise reaches its maximum value.
