Bently Nevada 330130-045-00-00 Extension Cable – 3300 XL Proximity System Cabling

The Bently Nevada 330130-045-00-00 is a dedicated extension cable for the 3300 XL proximity transducer system, used to link a proximity probe to its Proximitor sensor. It’s the kind of part that seems small but, in many cases, decides whether your vibration measurements stay clean and stable.

From my experience, this model is typically used where routing inside machinery skids or long conduit runs demand a reliable, factory-terminated coax cable. If you’re standardizing across rotating assets—compressors, turbines, large pumps—this piece helps keep system length within spec and protects signal integrity.

• 3300 XL ecosystem compatibility – Designed for Bently Nevada 3300 XL proximity probe systems, ensuring proper impedance matching and signal quality.

• Factory-terminated connectors – Reduces installation time and, typically, avoids field-termination issues that cause intermittent readings.

• Stable signal transmission – Coaxial construction suited for low-level proximity probe signals over extended runs between the machine and the Proximitor sensor.

• Length designation “045” – Commonly understood in the 330130 series as a nominal 4.5 m extension; always verify total system length with your selected probe to meet specification.

• Non-armored standard cable – Suitable for clean routing in conduit or protected trays; for harsher environments, many users consider the armored alternative in the 330180 series.

• Drop-in spare – Keeps critical assets online; in many cases it’s a simple swap when you’re troubleshooting cabling in a shutdown window.

You’ll typically see the 330130-045-00-00 used wherever precise shaft vibration or position measurements are critical:

• Steam and gas turbines, generator sets, and critical compressors

• Refinery and petrochemical pumps, fans, blowers, and expanders

• Paper, steel, and power plants with 3500 monitoring racks and 3300 XL probes

• OEM skid packages where consistent, documented cabling is required

• Assured compatibility – Works with common 3300 XL 5 mm and 8 mm probe families (e.g., 330103 / 330104) and their Proximitor sensors.

• Lower risk during turnarounds – Factory-terminated ends cut down on field mistakes that often cause late-night hunts for intermittent faults.

• Lifecycle efficiency – Standardized cabling helps spares management and reduces time to restore after a cable fault.

• Proven reliability – Many users report cleaner baselines after replacing aged or field-repaired cables with genuine 330130 units.

Feedback I hear a lot: “We swapped in a 330130-045-00-00 during outage and the proximitor bias settled immediately—no more drift on start-up.”

• Environment – Route in clean conduit or tray away from high-voltage lines and VFD cables. Maintain ventilation in cabinets housing Proximitors.

• Bend radius – Avoid sharp bends; follow a gentle sweep to protect the coax and maintain impedance.

• System length – Verify total transducer system length (probe + extension cable) meets the specification for your 3300 XL setup.

• Connections – Seat connectors firmly and keep them clean and dry; a light inspection during outages helps prevent intermittent noise.

• Routine checks – Periodically confirm continuity/insulation resistance and visually inspect for abrasion or crushed sections.

• Spares – Keeping a like-for-like spare on hand typically shortens unplanned downtime.

• Manufactured within an ISO 9001 quality system

• CE and RoHS compliance for most deployments (verify project documentation)

• Manufacturer’s warranty: typically 1 year for genuine parts

• 330103 (5 mm) and 330104 (8 mm) proximity probes for 3300 XL systems

• 3300 XL Proximitor sensors matched to probe/cable lengths

• 330180 armored extension cable series for high-abrasion or exposed routes

• 3500 monitoring racks and modules for protection and condition monitoring
