Working Principle The probe tip contains a coil energized by the Proximitor sensor with a high-frequency RF signal. The electromagnetic field induces eddy currents in the nearby conductive target. The energy absorbed by these eddy currents changes the coil impedance, which the Proximitor sensor converts to a DC voltage signal proportional to the probe-to-target gap distance.
Installation Requirements
- Thread into M10 x 1 mounting hole
- Position probe tip perpendicular to shaft surface
- Adjust gap to achieve -9 VDC output
- Tighten locknut securely against mounting surface
- Connect to matching 3300 XL extension cable and Proximitor sensor
Operating Considerations
- Ensure target material is conductive and ferromagnetic
- Maintain probe gap within linear range
- Avoid contact between probe tip and rotating components
- Protect cable from chemical exposure and mechanical abrasion
- Verify electrical continuity during preventive maintenance
