Function and Working Principle
The Bently Nevada 330702-00-25-10-02-00 operates based on eddy current measurement technology.
The probe creates a high-frequency electromagnetic field around the sensing tip. When the probe is positioned near a conductive shaft surface, the electromagnetic field changes according to the distance between the probe and the target.
These changes are converted into electrical signals that represent shaft displacement and vibration characteristics. The monitoring system uses this information to evaluate machine health and provide early warning of potential mechanical problems.
