Bently Nevada 330730-040-00-00 – 3300 XL 11 mm Extension Cable (4.0 m) for Proximity Transducer Systems

This is the Bently Nevada 330730-040-00-00 extension cable for the 3300 XL 11 mm proximity transducer system. From my experience, it’s the reliable link between the 11 mm probe at the machine and the Proximitor sensor tucked safely inside a cabinet. You might notice that the -040 length code corresponds to a 4.0 m cable, which is handy when you’re tuning total system length or dealing with tight routing in a skid.

Key Features

• Genuine 3300 XL 11 mm system cable – Built for pairing with the 11 mm probe and the matching 3300 XL Proximitor sensor.
• 4.0 m length (code -040) – Useful when you need specific run lengths for cabinet layouts or skid designs.
• Factory-terminated connectors – No field crimping; helps maintain signal integrity and calibration stability.
• Robust industrial jacket – Designed for harsh environments common to turbines, compressors, and large pumps.
• Signal integrity – Coax construction carries the eddy-current probe signal with excellent noise immunity, typically reducing false trips.
• Drop-in replacement – Fits existing 3300 XL 11 mm transducer setups without electrical rework in most cases.

Technical Specifications

Application Fields

Used across rotating equipment monitoring where 11 mm probes are specified:

• Steam and gas turbines – bearing vibration and shaft position.
• Compressors and expanders – continuous condition monitoring.
• Large pumps, fans, and drives – displacement and vibration measurements.
• Refining, petrochemical, and power generation plants – harsh, EMI-prone environments.

One thing I appreciate is how the 4.0 m length often solves cabinet-to-machine routing without leaving coils of unused cable in the tray. A maintenance lead told us it “saved an hour per train during turnarounds” simply by matching runs more closely.

Advantages & Value

• Reliability – Factory-terminated, shielded coax helps keep noise out and measurements stable.
• Compatibility – Matches the electrical characteristics expected by the 3300 XL 11 mm transducer chain.
• Cost control – Correct cable length typically reduces rework, splicing, or excess inventory.
• Support – Easy for technicians: no special tools for terminations and fewer field variables.

Installation & Maintenance

• Use clean, dry cable routing with proper strain relief; avoid crushing or tight bends (gentle radius is best).
• Keep separation from high-voltage power cables to minimize EMI; metallic conduit or tray shields help in many cases.
• Do not splice or shorten; select the correct length to preserve transducer calibration.
• Verify connectors are fully seated and locked; a light twist can confirm engagement without over-torquing.
• During shutdowns, wipe down the jacket, check for nicks/abrasion, and confirm continuity end-to-end.

Quality & Certifications

The 3300 XL series is built for industrial environments and, in many cases, aligns with major compliance regimes such as CE and RoHS. Exact conformity can vary by manufacturing batch and destination market, so we typically confirm against the latest datasheet on request.

Warranty: 365 days (our supply). If you need test reports or a certificate of conformity for documentation, we can include them with the shipment.
