Product Overview
The Bently Nevada 21504-00-08-10-02 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.
It uses eddy-current sensing technology to provide continuous, accurate, and reliable monitoring of critical rotating equipment such as turbines, compressors, pumps, and generators. The 1-meter total length makes it suitable for standard industrial mounting and flexible installation routing.

Function and Working Principle
The 21504-00-08-10-02 operates using eddy-current technology:
- The probe generates a high-frequency electromagnetic field at its tip.
- When near a conductive target such as a rotating shaft, eddy currents are induced in the surface.
- Changes in the probe-to-target gap modify the electromagnetic field.
- These changes are converted into electrical signals proportional to shaft vibration and displacement.
This non-contact measurement method eliminates mechanical wear and supports long-term stability.
