Product Overview
The Bently Nevada 21504-000-016-05-02 is a 7200 Series 8 mm Standard Mounting Proximity Probe designed for non-contact measurement of shaft vibration, displacement, and position in rotating machinery.
It is part of the 7200 eddy-current proximity system, which provides continuous, high-accuracy monitoring for critical industrial equipment such as turbines, compressors, pumps, and generators. The 8 mm probe diameter and 0.5 m total length make it suitable for compact installations where shorter probe routing is required.

Function and Working Principle
The 21504-000-016-05-02 operates using eddy-current technology:
- The probe generates a high-frequency electromagnetic field at its tip.
- When placed near a conductive rotating shaft, eddy currents are induced in the surface.
- Changes in the gap between probe and shaft modify the electromagnetic field.
- These variations are converted into electrical signals representing vibration and displacement.
Because it is non-contact, the probe avoids mechanical wear and ensures long-term stability.
