Product Overview
The Bently Nevada 21504-00-32-05-02 is an 8 mm standard mounting proximity probe from the 7200 Series, designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery.
Using eddy-current sensing technology, this probe delivers accurate, reliable, and continuous monitoring of critical equipment such as turbines, compressors, pumps, and generators. Its 0.5-meter total length makes it ideal for installations where shorter probe routing is required.

Function and Working Principle
The 21504-00-32-05-02 operates on eddy-current technology:
- The probe tip emits a high-frequency electromagnetic field.
- Conductive shafts in proximity induce eddy currents.
- Variations in the gap between probe and shaft change the electromagnetic field.
- These changes are converted into electrical signals representing shaft vibration and displacement.
The non-contact operation ensures long-term reliability without mechanical wear.
