Function and Working Principle
The Bently Nevada 330171-24-40-05-02-00 proximity probe operates based on eddy current sensing technology.
The probe generates an electromagnetic field at the sensing tip. When the rotating shaft moves closer or farther away from the probe surface, the electromagnetic field changes.
These changes are converted into electrical signals representing shaft displacement and vibration levels. The signals are then processed by monitoring equipment to evaluate machine condition and detect possible mechanical problems.
