Function and Working Principle
The 21504-002-012-10-02 operates on eddy-current technology:
- The probe tip emits a high-frequency electromagnetic field.
- A conductive shaft in proximity induces eddy currents.
- Variations in the gap between probe and shaft modify the electromagnetic field.
- These changes are converted into electrical signals representing shaft vibration and displacement.
This non-contact operation prevents mechanical wear and ensures long-term reliability.
