Bently Nevada 330130-080-02-05 – 80 ft Extension Cable for 3300 XL Proximity Transducer Systems

The Bently Nevada 330130-080-02-05 is an 80-foot (approx. 24.4 m) low-noise extension cable designed for 3300 XL proximity transducer systems. It links 5 mm/8 mm proximity probes to their Proximitor sensors, keeping the eddy-current displacement signal clean and stable over longer routes. From my experience, this length is often chosen when probes are mounted on large machines—turbines, compressors, and big process pumps—where the monitor rack or junction box sits a fair distance away.

Key Features

• Matched for 3300 XL 5 mm/8 mm systems – Ensures proper transducer system performance when used with the corresponding probe and Proximitor.
• 80 ft factory-defined length – Stable scale factor and phase response over typical cabinet-to-machine distances.
• Low-noise, double-shielded coax – Helps reject EMI in high-voltage and VFD-heavy environments.
• Rugged connectors – Secure locking connectors simplify field replacement and reduce downtime.
• High-temperature jacket – Typically suitable for harsh plant conditions around rotating equipment.
• API 670-friendly practice – Commonly used in API 670-aligned machinery protection architectures.
• Backward compatibility – Works with established 3300 XL proximitor sensors (e.g., 330180 series) in most cases.

Technical Specifications

Application Fields

Used across machinery protection and condition monitoring setups where probe-to-monitor distance is significant:

• Steam and gas turbines with remote rack rooms
• Large compressors and expanders in petrochemical plants
• High-power motors, generators, and gearboxes
• Critical process pumps with cabinet-mounted monitors

One thing I appreciate is how predictable the signal behavior remains on these longer runs when the three transducer components are correctly matched. A maintenance supervisor recently mentioned they swapped in a 330130-080 unit during a turnaround and were back taking clean shaft vibration data in under an hour.

Advantages & Value

• Reliability in harsh areas – Double-shielded coax and robust connectors hold up well near high temperatures and oil mist.
• Compatibility assured – Designed to work with the 3300 XL family; typically a drop-in replacement for the same length code.
• Lower downtime – Pre-terminated ends reduce installation time during outages.
• Procurement clarity – Clear length and option coding makes spares management straightforward.
• Technical support – We can help verify your probe and Proximitor codes so the system stays “length-matched.”

Installation & Maintenance

• Cabinet and routing – Use standard industrial enclosures; route in conduit or tray away from high-power cables and VFD outputs to minimize EMI.
• Wiring best practices – Maintain the minimum bend radius (typically ≥ 25 mm), avoid crushing forces, and keep connectors clean and fully seated/locked.
• Grounding – Follow Bently Nevada grounding and shielding practices to preserve low-noise performance.
• Routine checks – Periodically inspect jacket condition and connector integrity; verify gap/bias voltage at the Proximitor during PMs.
• Spares strategy – Keep at least one matching-length spare per machine train; mixing lengths can affect calibration unless the entire transducer set is matched.

Quality & Certifications

• Manufactured within an ISO 9001-quality ecosystem (typical for the 3300 XL range)
• CE and RoHS conformity typically applicable to cable assemblies in this series
• Often used in systems meeting API 670 machinery protection guidance
• Warranty: 365 days (coverage against manufacturing defects)
