Bently Nevada 330190-085-00-00 – 8.5 m Proximity Transducer Extension Cable for 3300 XL Systems

The BENTLY NEVADA 330190-085-00-00 is a factory-terminated proximity transducer extension cable, typically used to connect a 3300 XL probe to its Proximitor sensor in rotating machinery vibration and shaft position measurements. The “-085” option indicates an 8.5 m cable length, which makes it handy when your cabinet-to-sensor routing needs a bit more reach without adding splices. From my experience, plants choose this part when they want a straight swap for an OEM cable and minimal recalibration time.

It’s designed for the 3300 XL transducer family and maintains the signal integrity required for accurate eddy-current measurements on turbines, compressors, large motors, and critical pumps. You might notice that using the correct cable length helps preserve the transducer system’s calibrated range and sensitivity—small detail, big impact on data quality.

Key Features

• 8.5 m OEM-length cable – The -085 length supports common cabinet-to-bearing runs without excess slack.
• Purpose-built for 3300 XL systems – Mates with Bently Nevada probes and Proximitor sensors for reliable shaft vibration and position monitoring.
• Factory-terminated, shielded coax – Preserves low-noise measurement paths; no field splicing needed in most cases.
• Stable signal performance – Helps maintain calibrated system lengths for accurate gap and vibration readings.
• Drop-in replacement – Simplifies maintenance turnarounds with predictable fit and routing.

Technical Specifications

Application Fields

This model is commonly deployed in:

• Steam and gas turbines – shaft vibration and axial position measurements
• Centrifugal compressors and expanders – radial vibration and rub detection
• Large motors, generators, and critical pumps – bearing and shaft condition monitoring
• API 670-compliant protection systems – maintaining calibrated transducer system lengths

A maintenance lead at a power plant summed it up well: replacing a damaged run with 330190-085-00-00 restored stable bias voltage at the Proximitor immediately, and they didn’t have to touch the rack configuration—exactly what you want during a tight outage window.

Advantages & Value

• Reliability – OEM-grade shielding and terminations reduce noise pickup and intermittent faults that can cause nuisance alarms.
• Compatibility – Intended for 3300 XL proximity systems; typically pairs with common probes (e.g., 8 mm) and Proximitor sensors in the same family.
• Cost control – Correct cable length avoids rework, unscheduled calibration, and extra labor during turnarounds.
• Support – We can assist with length selection and system matching (probe + extension cable + Proximitor) to keep the total system length in spec.

Installation & Maintenance

• Environment – Route away from high-voltage power cables and VFDs; use grounded metallic conduit where practical for added EMI immunity.
• Bend radius – Avoid tight bends; a gentle radius helps preserve the coax geometry and signal quality.
• Connections – Ensure clean, fully seated terminations at the probe and Proximitor. Do not splice the cable; use the correct length instead.
• Cabinet practices – Maintain good ventilation in protection system cabinets and keep transducer cabling separated from power wiring.
• Routine checks – During outages, verify insulation integrity, connector condition, and system bias/gap readings. Firmware updates apply to the rack, not the cable, but it’s wise to document readings after any rack changes.
• Cleaning – Wipe the cable jacket with a mild solvent-compatible cleaner if needed; avoid abrasives and ensure connectors stay dry and uncontaminated.

Quality & Certifications

• CE and RoHS conformity typically applicable for 3300 XL transducer components
• Manufactured under ISO 9001 quality systems (manufacturer level)
• Warranty: 365 days (our supply policy)

Frequently paired items (for reference): 3300 XL probes (e.g., 8 mm series) and 3300 XL Proximitor sensors. If you’re matching lengths across a multi-channel machine train, we can help verify the total system length so the sensitivity stays within published specs.
