Function and Working Principle
The 21500-00-08-35-02 operates using advanced eddy-current sensing 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 shaft position alter the strength of the eddy currents.
- These changes are converted into proportional electrical signals representing shaft displacement and vibration.
The non-contact measurement method eliminates mechanical wear while ensuring accurate and continuous monitoring.
