Bently Nevada 330103-00-05-05-02-CN – Extension Cable for 3300 XL 8 mm Proximity Transducer Systems

The 330103-00-05-05-02-CN is a Bently Nevada factory extension cable used between a 3300 XL 8 mm proximity probe and its Proximitor sensor. From my experience, the 330103 is the safe choice when you want the system to stay within Bently’s calibrated length and deliver stable vibration/shaft position measurements. The “-05” in this configuration typically indicates a 5 m cable length, paired with Bently’s self-locking connectors for a secure, repeatable connection in the field. You might notice that when the probe, extension cable, and Proximitor length are correctly matched, the system tends to hold calibration far better over time.

Key Features

• Calibrated system length – Designed to work as part of a matched 3300 XL 8 mm transducer set (probe + extension + Proximitor) to maintain factory linearity and accuracy.
• ClickLoc style connectors – The self-locking design typically resists loosening from vibration and simplifies field replacement without special tools.
• Industrial jacket and shielding – Built for machinery spaces; in many cases it holds up well against oil mist and electrical noise when routed correctly.
• Stable signal transmission – Preserves the unamplified eddy-current probe signal from the measurement point to the Proximitor sensor.
• Compatible with 3300 XL 8 mm hardware – Typically used with the 330104 8 mm probe and the corresponding 3300 XL 8 mm Proximitor sensor.
• Traceability – Genuine parts usually ship with identifiable lot and serial data, which helps maintenance teams document calibrations and replacements.

Application Fields

Typically applied anywhere 3300 XL 8 mm proximity measurement is needed: steam and gas turbines, compressors, gearboxes, pumps, and large motors. In many cases, reliability teams standardize on this cable to keep mixed-length transducer chains from skewing readings, especially where tight vibration alarm thresholds are in play.

Advantages & Value

• Reliability under vibration – The connector design seems to resist loosening, which reduces intermittent faults that are hard to trace.
• Guaranteed compatibility – Matching Bently Nevada cable with Bently probes/Proximitor sensors typically preserves the intended calibration curve.
• Lower lifecycle risk – Using genuine parts can cut nuisance trips and save hours of troubleshooting after shutdowns.
• Straightforward sourcing – Standard lengths help spares planning; the 5 m build is a common stocking item.

“We swapped a mixed-brand cable for the 330103 and the orbit and gap readings stabilized within the shift,” noted a maintenance engineer from a turbine line. That’s a small change that often pays back quickly.

Installation & Maintenance

• Environment – Route in metallic conduit or protected trays; keep clear of high-voltage lines and VFD outputs to limit EMI pickup. Ensure glands and seals are suited to the enclosure’s IP/NEMA rating.
• Cable handling – Avoid sharp bends; keep bend radius ≥ 25 mm. Do not crush or overtighten cable ties. Maintain strain relief at both terminations.
• Length matching – Always match probe, extension cable, and Proximitor lengths as a set. Mixing lengths can shift calibration and gap voltage.
• Connections – Make sure ClickLoc connectors are fully seated and locked. Keep mating surfaces clean and dry.
• Routine checks – Inspect insulation and connectors during outages; clean with lint-free wipes; verify continuity and insulation resistance if readings drift.
• System upkeep – When you update monitoring system firmware or configuration, reverify transducer OK/alarm limits to confirm stability.

Quality & Certifications

• Manufacturer quality system: ISO 9001 (typical for Bently Nevada production)
• Conformity: CE marking and RoHS compliance typically applicable to 3300 XL components
• Warranty: 365 days (supplier warranty)
