Function and Working Principle
The 21504-00-28-10-02 operates using eddy-current technology:
- The probe emits a high-frequency electromagnetic field at its tip.
- When a conductive shaft is present, 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 shaft vibration and displacement.
This non-contact method ensures long service life and reliable continuous monitoring.
