Product Overview
The Bently Nevada 21504-000-016-05-02 is an 8 mm standard mounting proximity probe from the 7200 Series, engineered for non-contact measurement of shaft vibration, displacement, and position in industrial rotating machinery.
This probe utilizes eddy-current technology for accurate, continuous, and reliable monitoring, and its 0.5-meter total length makes it ideal for installations requiring shorter probe routing or compact spaces.

Function and Working Principle
The 21504-000-016-05-02 probe works using eddy-current sensing:
- The probe tip emits a high-frequency electromagnetic field.
- A conductive target, such as a rotating shaft, induces eddy currents.
- Variations in the gap between probe and target alter the electromagnetic field.
- These variations are converted into electrical signals representing shaft vibration and displacement.
Being non-contact, the probe avoids mechanical wear and provides long-term operational reliability.
