BENTLY NEVADA 330130-040-00-00 – 4.0 m Extension Cable for 3300 XL Proximity Transducer Systems

The BENTLY NEVADA 330130-040-00-00 is a 4.0 m extension cable designed for the 3300 XL proximity transducer system, placed between the probe and the Proximitor sensor. From my experience, this is the go-to length for most turbine, compressor, and large motor bearing measurements where you want a clean signal path without excess slack. It’s a straightforward component, but it tends to make a big difference in signal stability and long-term reliability—especially around high-EMI machinery.

Key Features

• 4.0 m factory length – A practical run for most cabinet-to-bearing routes without unnecessary coiling.
• 3300 XL system compatibility – Typically used with 8 mm proximity probes and the 3300 XL Proximitor sensor line for vibration and position measurements.
• Coaxial, low-noise construction – Helps reject electrical noise around VFDs and large motors, keeping the mV/μm signal consistent.
• Secure connectors – The familiar Bently Nevada locking style helps avoid loosening during machine vibration and thermal cycles.
• Rugged industrial jacket – Built for oil and plant environments; seems to hold up well in most compressor and turbine skids.
• Drop-in replacement – Minimizes downtime; in many cases you can swap, route, click, and go straight into a bump test.

Technical Specifications

Application Fields

You’ll typically see the 330130-040-00-00 on:

• Steam and gas turbines – radial and axial position measurements on journal and thrust bearings.
• Compressors and expanders – continuous vibration monitoring tied into protection systems.
• Pumps and fans – condition monitoring in process plants where stable proximity signals matter.
• Generators and large motors – shaft relative vibration and runout checks.

One thing I appreciate is how predictable the signal looks after replacing aged cables—noise floor drops, and the proximity gap trend becomes cleaner. A maintenance supervisor at a gas plant told me their nuisance trips disappeared once they standardized on fresh 3300 XL cabling during turnaround.

Advantages & Value

• True system compatibility – Reduces risk of calibration drift or scaling errors versus generic cable swaps.
• Signal integrity – Coax design helps maintain mV/μm accuracy across the run length, even around VFDs.
• Lower downtime – Quick, repeatable connections; less time in the cabinet during outages.
• Lifecycle cost – In many cases, a correct cable eliminates hours of troubleshooting later on.
• Traceability – Clear part numbering simplifies spares management and audit trails.

Installation & Maintenance

• Environment: Use a clean, ventilated cabinet for the Proximitor; keep routing away from high-voltage lines and VFD outputs when possible.
• Routing: Use conduit or cable tray; avoid sharp bends (use a gentle radius) and keep cables secured to reduce vibration-induced wear.
• Connections: Ensure connectors are fully seated/locked; you might notice a positive “lock” feel when it’s correctly engaged.
• Grounding/Shielding: Maintain the manufacturer’s grounding scheme to prevent ground loops.
• Routine checks: Inspect jacket condition, connector engagement, and cleanliness; verify system scale factors and perform a quick gap check after any cable change.

Quality & Certifications

• Compliance: Bently Nevada 3300 XL components are commonly CE and RoHS compliant; specific declarations are available from the manufacturer.
• Warranty: 365-day warranty provided by us.
