BENTLY NEVADA 330130-080-01-05-RU – 8.0 m Extension Cable for 3300 XL Proximity Transducer Systems

The 330130-080-01-05-RU is a factory-matched extension cable used to connect Bently Nevada 3300 XL proximity probes to their Proximitor sensors. From my experience, getting the system length right is what keeps your vibration and position measurements stable over the long haul, and this cable is built for exactly that. The “080” code indicates an 8.0 m cable length; the “-RU” variant typically denotes a Russia/EAC-oriented option set and documentation, which in many cases helps with site approvals and spares traceability.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than one month at the latest
• Payment: 50% advance payment; full payment before delivery
• Express delivery: FedEx, UPS, DHL

Key Features

• Matched 8.0 m system length – helps maintain calibrated probe–cable–Proximitor performance for consistent gap and vibration readings.
• 3300 XL compatibility – designed for use with Bently Nevada 3300 XL proximity probes and Proximitor sensors in critical machinery monitoring.
• Low-noise, shielded coax construction – typically excellent immunity to EMI found around large motors, VFDs, and turbine starter systems.
• Factory-terminated connectors – reduces installation time and limits handling errors that can introduce measurement drift.
• Industrial temperature capability – suitable for most rotating equipment environments when routed correctly away from heat sources.
• “-RU” option set – appears to address EAC/Russia market needs, which can simplify regional compliance and documentation.
• Drop-in replacement – useful for maintenance turnarounds when you need to restore original system lengths without re-calibration headaches.

Technical Specifications

Application Fields

You’ll typically see this cable on critical rotating assets where proximity transducers are standard practice:

• Gas and steam turbines – shaft vibration and differential expansion monitoring
• Compressors and expanders – radial vibration and shaft position (X/Y) channels
• Pumps, fans, and blowers – imbalance, misalignment and bearing condition trends
• Refining, petrochemical, power generation, pulp & paper, and mining environments

Advantages & Value

• Measurement integrity – using the correct cable length preserves the factory calibration of your probe/Proximitor pair.
• Seamless compatibility – avoids mixed-cable issues that can skew gap readings or add noise.
• Reduced downtime – quick, like-for-like replacement during outages; no custom termination on site.
• Lifecycle savings – stable signal quality often means fewer nuisance alarms and less troubleshooting time.
• Documentation support – “-RU” variant seems to ease regional approvals and acceptance testing in many cases.

Installation & Maintenance

• System length discipline – match the extension cable to your probe and Proximitor to maintain the intended total system length.
• Routing best practices – keep away from high-voltage runs and VFD outputs; use shielded trays or metallic conduit where practical.
• Bend radius – avoid tight bends or repeated flexing; gentle routing typically preserves dielectric and shielding performance.
• Grounding – bond shields as per the 3300 XL installation guide to minimize common-mode noise.
• Connector care – keep ends clean and dry; finger-tighten per manufacturer guidance and avoid over-torque.
• Routine checks – visually inspect insulation each outage, verify continuity, and re-verify gap readings after any cable change.

Quality & Certifications

• Conformity: typically CE and RoHS for the cable family; “-RU” options often align with EAC regional requirements.
• Manufacturer warranty: 365 days (supply warranty as stated above).

Supporting Components (for planning and spares)

To complete a 3300 XL proximity transducer channel, you’d pair this extension cable with:

• 3300 XL proximity probe (5 mm or 8 mm types, depending on target and fit-up)
• 3300 XL Proximitor sensor (matching the selected probe and total system length)
• Mounting hardware and brackets suitable for your machine casing and bearing housing

You might notice that plants often standardize on a few cable lengths to keep spares simple. If you’re unsure whether the 8.0 m is right for your loop, share your current probe length and Proximitor type—matching those correctly typically saves troubleshooting later.
