Working Principle The probe operates using eddy current technology. The probe coil, energized by the Proximitor sensor, creates an electromagnetic field at the probe tip. When a conductive target is present, circulating eddy currents are generated in the target material. The Proximitor sensor detects the resulting impedance change and generates a DC voltage output that varies linearly with the distance between probe tip and target surface.
Installation Requirements
- Mount in M10 x 1 threaded hole of appropriate depth
- Maintain perpendicular orientation to target surface
- Set initial gap voltage within linear range
- Secure with locknut to prevent loosening
- Connect to compatible 3300 series extension cable and Proximitor sensor
Operating Considerations
- Use with matching 3300 series system components
- Verify target material matches calibration standard
- Avoid probe-to-shaft contact during operation
- Inspect cable and connector condition regularly
- Replace if probe tip shows wear or damage
