Work through this checklist before replacing a 3300 XL 8 mm Proximity Probe System unit — most field symptoms trace to wiring, grounding, or configuration rather than a failed module.
Key points at a glance
- Tip diameters: 5 mm, 8 mm standard; case lengths and threads per the installed system
- Gap voltage is set at the Proximitor; keep probe-cable-Proximitor as one calibrated set
- Standard tip options: threaded, smooth bore, and reverse-mounted
- High-temperature variants available up to 260 °C on request
- Every part number lists tip, thread, case length, and connector
Swap-test with the configured spare last: if the symptom follows the module, order the replacement; if it stays, the problem is in the loop.
