How to detect the electrodynamic vibration probes of the turbine unit?
Thread Content
For unit maintenance, TK3 can be used to inspect the eddy current displacement probes; this has been done. But it’s not very clear from the instructions how the vibration probe works. I wonder who has done testing on vibration probes. Once the probe is connected, how should one conduct the testing, using a multimeter or an oscilloscope? Are there any sample forms for filling out the checks?
The static calibration of the vibration probe is the same as that for displacement; this is sufficient. If dynamic verification is to be performed, use the swash plate of TK-3 and a dial indicator.
