Testing Bearings With Ultrasound
When collecting bearing data consistent placement of the contact probe is critical to repeatability. Care should be taken to position the probe at the same place each time. Wherever possible a ninety degree angle between probe and bearing should be realized. Modern ultra sound systems are less subject to hand pressure then older systems. However a firm and consistent hand pressure should be applied. Better still, use a magnetic mount with a RS1 threaded sensor. Measurement should be taken in the following sequence.
1.) Position probe on bearing
2.) Set amplification
3.) Set acquisition sample time
4.) Listen with headset
5.) Begin capture and store
6.) If alarm is triggered capture dynamic data for time waveform analysis.
