Bently Nevada 330130-045-02-05 Extension Cable – Reliable Interconnect for 3300 XL Proximity Systems

The Bently Nevada 330130-045-02-05 is a 4.5 m 3300 XL extension cable designed to connect 3300 XL proximity probes to the matching Proximitor sensor. From my experience, this is the piece that preserves your calibrated transducer length and keeps vibration/position measurements stable, even around high EMI equipment. It’s a straightforward swap in most installed bases where 3300 XL hardware is standard.

• Calibrated system length control – The 4.5 m cable helps maintain the overall 3300 XL transducer system length for factory calibration consistency.

• Stable, low-noise signal path – Triax-style coax construction with robust shielding typically reduces EMI/RFI pickup near drives, large motors, or switchgear.

• 3300 XL connector compatibility – Mates directly with 3300 XL proximity probes and their matching Proximitor sensors for a drop-in fit.

• Mechanical security – Positive-lock style connectors (common across 3300 XL) help prevent loosening due to vibration.

• Ruggedized for industry – Jacket and construction are built for routing in machine skids and cabinets; armored variants exist in the series if required by your spec.

• Option-coded flexibility – The “-02-05” options typically indicate connector/approval configurations; we can verify exact details against your installed base before shipping.

This cable is commonly used across turbomachinery protection and condition monitoring: steam and gas turbines, compressors, expanders, large motors, generators, pumps, gearboxes, and critical fans. You might notice that machines with higher magnetic fields or VFDs benefit from the cable’s shielding; signal noise tends to drop compared to generic coax. A maintenance lead from a refinery told me they swapped this exact length during a short outage and their shaft relative position trend stabilized right away.

• Drop-in with existing 3300 XL assets – Reduces downtime and avoids recalibration risk when matched to your system length.

• Measurement integrity – Better shielding and connector retention typically translate into cleaner vibration/position data.

• Spares strategy friendly – Keeping common lengths like 4.5 m on the shelf seems to be the most cost-effective approach many plants take.

• Traceability and support – Easy to verify option codes against your transducer BOM before shipment to avoid mis-matches.

• Environment – Route in cabinet or conduit where possible. Avoid parallel runs with high-voltage cables; cross at 90° when you must.

• Cable handling – Maintain a gentle bend radius (typically several times the cable diameter). Use strain relief near probe and Proximitor ends.

• Connector care – Keep connectors clean and dry; use lint-free swabs with isopropyl alcohol for light cleaning. Ensure connectors are fully seated and locked.

• System length check – When replacing, match the probe + extension cable to your Proximitor calibration length to preserve accuracy.

• Routine inspection – Periodically check for abrasion, crushed sections, or loose connectors. If signal drift appears, verify continuity and connector condition first.

• Firmware and calibration – The cable itself has no firmware; however, keep your monitoring rack or transmitter firmware current and verify transducer calibration during planned outages.

• Quality system – Manufactured under ISO 9001 quality processes (typical for Bently Nevada hardware).

• CE / RoHS – Generally compliant; hazardous area approvals (e.g., ATEX/IECEx/CSA) may be available by specific option code. We can confirm against “-02-05”.

• Warranty – Standard manufacturer warranty typically 1 year; extended coverage can be arranged in many cases.

Quick check before ordering: share the probe model, Proximitor model, and required system length. That way we verify the 330130-045-02-05 matches your calibration and any site-specific approvals.
