Bently Nevada 330130-080-01-00 – 8.0 m Extension Cable for 3300 XL Proximity Transducer Systems

The Bently Nevada 330130-080-01-00 is an 8.0 meter extension cable designed for 3300 XL proximity transducer systems. From my experience, this series is the go-to choice when you need stable displacement and vibration measurements on rotating assets and you want to keep the Proximitor sensor in a cooler, protected cabinet. It seems to be the “safe pick” for brownfield upgrades because it mates cleanly with existing 3300 XL 5 mm and 8 mm probes and Proximitor sensors without signal mismatches.

Key Features

• Matched to 3300 XL systems – Ensures proper system length when combined with the probe and Proximitor sensor for accurate eddy-current measurements.
• 8.0 m cable length – Gives flexibility to mount the Proximitor in a cooler, accessible cabinet while the probe remains at the machine.
• Stable signal integrity – Coaxial design maintains low noise and consistent sensitivity, which typically shows up as cleaner displacement and vibration data.
• Drop-in compatibility – Pairs with Bently Nevada 3300 XL 5 mm and 8 mm probes and Proximitor sensors; handy for mixed fleets and phased retrofits.
• Rugged industrial build – Suited for continuous-duty turbomachinery environments with proper routing and protection.

Application Fields

You’ll typically find the 330130-080-01-00 in continuous monitoring of turbomachinery and critical rotating equipment:

• Steam and gas turbines (radial and axial displacement monitoring)
• Compressors and expanders (shaft vibration, casing proximity points)
• Large motors, generators, and pumps (bearing and shaft position)
• Gearboxes and blowers where the Proximitor is cabinet-mounted for accessibility

One thing I appreciate is how it simplifies retrofits: you can keep your proven 3300 XL probes on the machine, pull this cable back to a cooler electrical room, and maintain measurement fidelity without reworking the sensor chain.

Advantages & Value

• Reliability – Stable eddy-current signal path reduces drift and nuisance alarms in many cases.
• Compatibility – Works with 3300 XL probes and Proximitor sensors; less engineering time during upgrades.
• Cost efficiency – Reuse existing probes and Proximitor hardware; fewer field changes and less downtime.
• Support-ready – Clear traceability by model number makes spares planning and field service simpler.

Installation & Maintenance

• Mounting & routing – Route in metallic conduit or tray where possible. Keep clear of high-temperature surfaces and high-voltage runs to minimize EMI coupling.
• Bend radius – Avoid sharp bends; a generous bend radius helps maintain impedance and signal integrity.
• Connections – Verify tight, clean connector engagement at both the probe and Proximitor ends. You might notice that reseating connectors often resolves noisy traces.
• Grounding & shielding – Follow plant grounding practices; keep cable shields continuous and avoid unintentional grounds.
• Periodic checks – Inspect insulation and boots during shutdowns, clean with lint-free wipes, and confirm system length matches monitoring configuration.

Quality & Certifications

• Manufactured under ISO 9001 quality systems (typical for Bently Nevada production)
• CE compliant; RoHS conformity typically applicable for cable assemblies
• Warranty: 365 days (our supply guarantee)

Compatible Components (for planning)

To build a complete measurement chain, this cable is commonly paired with:

• 3300 XL 5 mm or 8 mm Proximity Probes (e.g., 330103 series)
• 3300 XL Proximitor Sensors (5 mm / 8 mm series)

A maintenance lead from a gas plant told me their shaft vibration trend stabilized after swapping to the correct 330130 length because the total system length finally matched the monitor’s configuration. It’s a small detail that saves hours of chasing noise.
