Function and Working Principle
The Bently Nevada 330171-20-55-05-02-05 proximity probe operates based on eddy current sensing technology.
The probe generates a high-frequency electromagnetic field through the sensing tip. When the rotating shaft moves closer or farther away from the probe, the electromagnetic field changes accordingly.
These changes are converted into electrical signals that represent shaft vibration and displacement conditions. The monitoring system processes these signals to evaluate equipment performance and detect possible mechanical problems.
