Performance Parameters:
- Measurement accuracy: ±5% of full scale
- Frequency coverage: Suitable for thermal expansion signals
- Temperature stability across full operating range
Material Composition:
- Stainless steel probe housing
- Gold-plated brass ClickLoc connectors
- Shielded coaxial cable construction
Structural Features:
- 25mm probe with extended linear range
- Multiple thread options for flexible mounting
- Proximitor available in DIN-rail or panel mount
Working Principle:
Eddy current non-contact measurement — high-frequency electromagnetic field from the probe coil induces eddy currents in the conductive target, changing coil impedance proportionally to gap distance. The Proximitor converts this to a linear DC voltage output over the 12.7mm range.
Installation Requirements:
- Match extension cable length to Proximitor system length designation
- Set initial gap at linear range midpoint
- Verify output voltage at calibrated position
- Route signal cables away from power cables
Usage Notes:
- Verify specific configuration options encoded in the part number match application requirements
- Compatible with 3500 monitoring system with appropriate software version
- All components must be 3300 XL 25mm family for guaranteed interchangeability
