Sonar device FAG SOUND-CHECK

Sonar device FAG SOUND-CHECK

The sonar detector can be used to check rolling bearing noise very easily, quickly and reliably.

Changes in noise due to wear, pitting formation or distortion of the bearing can be detected at an early stage if regular inspection is carried out. In this way, unforeseen operational stoppages and more significant machine damage can be prevented.

The device is used in the same way as a doctor’s stethoscope. The tips of the earpiece are placed in the ear canals to provide insulation against background noise. The insulated grip is held between the thumb and index finger like a pencil. The sensor is placed firmly on the part to be measured. If a noise is heard, the sensor is moved until its volume reaches a maximum.
