Function and Working Principle
The 21504-000-012-10-02 operates using eddy-current sensing:
- The probe tip emits a high-frequency electromagnetic field.
- When near a conductive target, such as a rotating shaft, eddy currents are induced in the target.
- Changes in the gap between the probe and the target alter the electromagnetic field.
- These changes are converted into electrical signals proportional to shaft vibration, displacement, and position.
Being non-contact, this probe reduces mechanical wear and ensures long-term reliability.
