Bently Nevada 330130-085-02-05 – 3300 XL Extension Cable for Proximity Transducer Systems

The Bently Nevada 330130-085-02-05 is an 8.5 m 3300 XL extension cable designed to link 8 mm proximity probes to their associated Proximitor sensors. From my experience, this is the piece that often determines whether your vibration and position measurements stay clean over distance or drift with noise. It’s factory-terminated, shielded, and uses Bently’s robust connector system, which typically means you get predictable performance without fighting intermittent signals in the cabinet.

Key Features

• Purpose-built for 3300 XL 8 mm systems – Matches the electrical characteristics required for accurate eddy-current proximity measurements.
• 8.5 m length (085 code) – Reduces splices in long runs; you get consistent calibration from probe tip through the Proximitor sensor.
• Low-noise coaxial construction – Helps maintain signal integrity in cabinets where VFDs and high-current lines typically add noise.
• Secure connector system – The Bently-style positive-lock connectors resist loosening from vibration; hand-mate and you’re done.
• Industrial-grade jacket – Suitable for routing in machine skids and control panels; seems to be quite resistant to oils and most common chemicals.
• Traceability – Clear part number identification makes maintenance and future replacements straightforward.

Technical Specifications

Application Fields

You’ll usually see this cable on rotating assets where reliable proximity measurements matter: steam/gas turbines, compressors, large motors, gearboxes, and high-speed pumps. It’s widely used in condition monitoring and protection systems where the 3300 XL chain is standard. One thing I appreciate is how predictable it is when mixed into existing skids—retrofits tend to go smoothly if you match lengths correctly.

Advantages & Value

• Compatibility confidence – Designed for the 3300 XL 8 mm system, so calibration and gap readings typically remain within spec.
• Lower noise, fewer callbacks – Shielding and connector integrity help reduce sporadic spikes that eat up maintenance hours.
• Spares standardization – Using the exact length and series simplifies lifecycle management across multiple machines.
• Procurement assurance – Clear part coding and an established supply chain minimize lead-time surprises.

Installation & Maintenance

• Environment – Install in a clean, dry panel or routed in protected conduit/tray; allow ventilation and avoid tight bends.
• Routing – Keep the cable separated from high-voltage and VFD motor leads; cross at 90° if you must to limit induced noise.
• Bend radius – Use gentle radii and strain relief; don’t pinch under gland plates or sharp edges.
• Connections – Mate the locking connectors hand-tight until fully seated; you should feel a secure lock. Re-seat if the gap voltage seems unstable.
• Checks – After installation, verify probe gap and target response through the Proximitor. Re-check during outages for any loosened fittings.
• Care – Wipe dust/oil from the jacket periodically; avoid solvents that could degrade the sheath. Firmware updates don’t apply to the cable, but do keep the monitoring system current.

“We swapped to the 330130-085-02-05 during a compressor overhaul. Noise dropped noticeably and the prox signals stabilized; no more intermittent dropouts in the cabinet.” – Maintenance Supervisor, petrochemical plant

Quality & Certifications

• Compliance – Typically CE and RoHS compliant; manufacturer quality systems are ISO 9001 based.
• Warranty – 12 months coverage (365 days).

Suggested Companion Parts

• 3300 XL 8 mm Proximity Probe (matching tip size and thread as installed)
• 3300 XL Proximitor Sensor (for 5 mm/8 mm probes, per your rack/system configuration)
• Mounting hardware and feedthroughs as required by the machine casing

If you’re replacing an existing cable, match the full code (330130-085-02-05) so the length and connector options stay consistent with your calibration. You might notice that staying with the same length often avoids any need to rebaseline the system.
