Function and Working Principle
The 21504-000-052-10-02 operates using eddy-current displacement sensing:
- The probe generates a high-frequency electromagnetic field at its sensing tip.
- When near a conductive rotating shaft, eddy currents are induced in the surface.
- Changes in the gap between probe and shaft alter the electromagnetic field.
- These changes are converted into electrical signals proportional to vibration and displacement.
This non-contact method ensures no physical wear and enables continuous, reliable monitoring.
