Function and Working Principle
The 21500-04-02-10-02 operates using eddy-current technology:
- The probe generates a high-frequency electromagnetic field at its sensing tip.
- When positioned near a conductive target, eddy currents are induced in the target material.
- Variations in the distance between the probe and target alter the electromagnetic field characteristics.
- The resulting changes are converted into electrical signals proportional to shaft displacement and vibration.
This non-contact operating principle eliminates physical wear and enables continuous monitoring of rotating equipment.
