Performance Parameters The probe provides identical electrical performance to other 3300 XL 8mm ETR probes. The linear range is 2.0 mm (80 mils) with system linearity of ±0.025 mm (±1.0 mil). System sensitivity is 7.87 V/mm (200 mV/mil). The 6mm unthreaded length provides flexibility in mounting while maintaining the same sensing characteristics as other case lengths. The probe maintains calibration stability within ±1.0% across the full temperature range.
Material Composition Identical to other 3300 XL 8mm ETR probes: PPS probe tip, AISI 303/304 stainless steel case, high-temperature internal coil, silver-plated copper cable conductor with fluoropolymer insulation, Viton O-ring seal. The 12mm case length provides additional material for heat dissipation from the probe tip to the mounting structure.
Structural Characteristics The probe features a cylindrical stainless steel case with M10x1 external thread and a 6mm smooth unthreaded section adjacent to the probe tip. The 12mm overall case length provides 6mm of threaded section for mounting plus 6mm of unthreaded section. The integral cable exits from the rear of the case. The probe tip is flat PPS with molded-in coil. The ClickLoc connector is at the cable end.
Working Principle Identical to other 3300 XL 8mm probes. The eddy current principle creates an electromagnetic field at the probe tip; energy loss in the conductive target modulates the RF signal from the Proximitor. The ETR design uses high-temperature materials to maintain stable electrical characteristics across the extended temperature range.
Installation Requirements
- Drill and tap mounting hole with M10x1 thread to appropriate depth (typically 8-10mm)
- The 6mm unthreaded length allows the probe to be positioned with the smooth section extending into the mounting structure
- Ensure the probe tip is at the correct distance from the target surface
- Apply anti-seize compound to threads
- Tighten to 20-25 N·m torque
- Route cable away from heat and moving parts
- Connect to ETR extension cable or Proximitor with ClickLoc connector
Usage Precautions
- Do not expose cable or connector to excessive temperatures
- Maintain minimum 25mm bend radius for cable
- Check probe tightness periodically
- Inspect probe tip for damage or contamination
- Verify target material matches calibration
- Monitor output for drift indicating loosening or material changes
- Replace if tip is damaged or output is erratic
- Store spares in original packaging
- Follow ESD precautions
