Product Overview
The Bently Nevada 21504-00-16-05-02 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.
It is part of Bently Nevada’s eddy-current proximity measurement system, widely used for continuous condition monitoring and machinery protection in turbines, compressors, pumps, generators, and other rotating equipment. The 0.5-meter total length makes it suitable for compact installations or short routing paths.

Function and Working Principle
The 21504-00-16-05-02 operates using eddy-current technology:
- The probe emits a high-frequency electromagnetic field from its tip.
- When near a conductive rotating shaft, eddy currents are induced in the surface.
- Changes in the probe-to-shaft gap modify the electromagnetic field.
- These variations are converted into electrical signals proportional to shaft vibration and displacement.
Because it is non-contact, the probe avoids mechanical wear and ensures stable long-term performance.
