Expert Review – Manager’s Insight

• 8 mm advantage: Thicker PPS encapsulation and larger body offer superior robustness. Preferred for high‑stress rotating equipment.
• FluidLoc value: Prevents oil leakage through cable – a true reliability upgrade in lube oil systems.
• 9 m total length: Perfect when monitor rack is far from machine, eliminates extra junction boxes.
• 5 mm alternative: For tight installations, the 3300 5mm series offers similar performance in smaller thread sizes.

Selection Guide – Compare Similar Models

• 330191-40-75-15-05 – ATEX certified, 1.5 m cable, short system. Best for compact installations.
• 330191-40-75-15-00 – 7.5 inch case, 1.5 m cable, no agency approvals. Cost‑effective for general purpose.
• 330191-00-16-90-05 (this item) – 9 m total length, full hazardous approvals, longest cable. Recommended for remote monitoring racks.

Frequently Asked Questions (FAQ)

• What machines typically use this 3300 XL 8 mm probe?Steam turbines, centrifugal compressors, gearboxes, large pumps, and any critical rotating asset requiring eddy‑current measurement.
• Can I use this probe with a 5 mm extension cable?No. Use only 8 mm Bently Nevada extension cables to maintain system accuracy.
• How do I select between 5 mm and 8 mm probes?8 mm offers greater durability. Choose 5 mm when mounting space is limited or retrofitting older 5 mm holes.
• What does “ETR” mean in the model?Extended Temperature Range – probe cable insulation rated for higher temperatures (PFA for ETR versions).
• Is the 9 m length including the probe tip?Yes. Total length from tip to connector is 9.0 meters. It is a one‑piece system; no extension cable required.
• Do you ship internationally?Yes. We ship worldwide via FedEx, UPS, or DHL. Typical dispatch within 12‑24 hours.
• Can I get a shorter version with the same approvals?Yes. Models like 330191-XX-XX-15-05 (1.5 m) share the same approvals. Contact us for availability.
