Working Principle The probe operates through eddy-current induction. The coil within the probe tip generates a high-frequency electromagnetic field when excited by the Proximitor sensor. Conductive targets entering this field induce eddy currents that modify coil impedance. The Proximitor converts this impedance change into a proportional voltage output representing both static gap and dynamic vibration.
Installation Requirements
- Mount in M10×1 threaded hole with 10 mm counterbore for unthreaded section
- Ensure perpendicular alignment to target surface
- Set probe gap to 1.0 mm
- Verify -10 Vdc gap voltage
- Maintain 25.4 mm minimum bend radius for armored cable
- Install connector protector after mating extension cable
Usage Precautions
- Verify counterbore depth accommodates 10 mm unthreaded length
- Do not kink or crush armored cable during installation
- Armor provides abrasion resistance but not crush protection
- Connector protector must be installed to maintain environmental seal
- Inspect armor braid for damage before installation
- Armored cable is less flexible; plan routing carefully
