Function and Working Principle
The 21500-00-12-05-02 operates using eddy-current technology:
- The probe tip generates a high-frequency electromagnetic field.
- When positioned near a conductive target such as a rotating shaft, eddy currents are induced in the target surface.
- Changes in the distance between the probe and target alter the electromagnetic field.
- These variations are converted into electrical signals proportional to shaft movement and vibration.
This non-contact measurement method ensures high reliability without mechanical wear.
