Bently Nevada 330130-085-03-00 – Extension Cable for 3300 XL Proximity Transducer Systems

The Bently Nevada 330130-085-03-00 is an 8.5 m pre-terminated extension cable typically used between a 3300 XL proximity probe and its Proximitor sensor. From my experience, this is the go-to length when you need a clean routing path in larger machines without introducing excess slack. It maintains the system’s calibration chain when matched to the appropriate probe and Proximitor, which is exactly what reliability teams want to see during audits.

Key Features

• 8.5 m factory-terminated length – The 085 code indicates 8.5 meters, which suits most compressor, turbine, and large motor layouts.
• Purpose-built for 3300 XL systems – Designed to carry the eddy-current transducer signal between probe and Proximitor with stable impedance.
• -03 end option – Connector/jacket option for this cable family; in many cases it suits standard non-armored routing. We can double-check against your installed base.
• Shielded coax construction – Helps reduce noise pickup in electrically busy panels and tight cable trays.
• Rugged jacket – Typically FEP/Tefzel-type insulation for industrial environments; handles oils and common plant contaminants well.
• Drop-in replacement – No field terminations required; reduces install errors and line downtime.

Technical Specifications

Application Fields

You’ll typically find this cable in rotating machinery monitoring—compressors, steam/gas turbines, large motors, generators, and critical pumps. It’s often specified by reliability teams who want consistent transducer performance across long runs or through protected cable trays. One thing I appreciate is how it helps maintain signal integrity in high-EMI areas around VFDs and switchgear when routed properly.

Advantages & Value

• Reliability – Factory connectors reduce termination errors and intermittent faults that can be hard to trace.
• Compatibility – Pairs with standard 3300 XL probes/Proximitors, so spares management is straightforward.
• Lower total cost – Less rework and faster installs, especially during shutdowns when every hour counts.
• Support – We can help validate -03 option fit with your existing transducers before shipping.

Installation & Maintenance

• Environment – Install in a ventilated cabinet or protected tray; avoid hot spots exceeding the jacket’s temperature rating.
• Routing – Keep clear of high-voltage lines; maintain separation from VFD outputs; use continuous shielding and proper grounding at the Proximitor end.
• Bend radius – Follow a gentle bend radius (many teams use ≥25 mm as a practical rule) to protect the coax.
• Connections – Ensure connectors are fully seated; lightly torque per OEM guidelines; do not overtighten.
• Maintenance – Periodically inspect for abrasion, chemical exposure, and clamp integrity; clean connectors; re-verify gap readings during scheduled calibrations.
• Safety – Lockout/tagout the machine; prevent ESD damage when handling transducer components.

Commonly Paired Components

• 3300 XL proximity probes (5 mm, 8 mm, and NSv types as required by rotor/stiffness)
• 3300 XL Proximitor sensors matched to the probe type and cable length
• Mounting accessories and bulkhead feed-throughs for cleaner cabinet integration

A maintenance lead at a gas plant told us they moved from 5 m to 8.5 m runs on two compressor trains to simplify tray routes—fewer junctions, fewer failure points, and easier troubleshooting after turnarounds.

Quality & Certifications

• Typically RoHS-compliant cable materials
• CE marking applicable when installed as part of a compliant monitoring system
• Manufacturer quality systems commonly aligned to ISO standards
• Warranty: 12 months from shipment (365 days)
