Function and Working Principle
The Bently Nevada 330171-20-55-05-02-CN proximity probe operates using eddy current sensing technology.
The probe generates an electromagnetic field through the sensing tip. When the rotating shaft changes position, the distance between the shaft surface and the probe tip changes, causing variations in the electromagnetic field.
These changes are converted into electrical signals that represent shaft displacement and vibration movement. The monitoring system processes these signals to evaluate machine operating conditions.
