Bently Nevada 330161-02-85-05-94-01-02 – Extension Cable for 3300/3300 XL Proximity Transducer Systems

The Bently Nevada 330161-02-85-05-94-01-02 is a factory-configured extension cable used between the proximity probe and the Proximitor sensor in 3300/3300 XL eddy-current transducer systems. It’s built for rotating machinery monitoring—think turbines, compressors, pumps, and large motors—where stable, low-noise signal transmission really matters. From my experience, this series cable is a safe choice when you need OEM-level integrity and predictable performance across long runs in harsh industrial environments.

Order Placement Process and Guarantees

Key Features

• Engineered for 3300/3300 XL systems – Mates with standard Bently Nevada probes and Proximitor sensors for displacement/vibration monitoring.
• Low-noise coaxial construction – Helps preserve signal quality over distance, typically reducing drift and interference in high-EMI areas.
• Rugged jacket and strain relief – Designed for routed cabinet or field installation; resists common oil and chemical exposure in most plants.
• Factory-terminated connectors – Consistent impedance and secure mating to minimize intermittent faults during machine starts and shutdowns.
• Build-code specific – The -02-85-05-94-01-02 configuration appears to define cable length and options; we can confirm the exact matrix against your BOM.
• Wide machinery coverage – Suitable for radial/axial position and vibration measurements on turbines, compressors, pumps, gearboxes, and generators.

Technical Specifications

Application Fields

This cable is typically specified wherever non-contact shaft vibration or position is monitored:

• Steam and gas turbines – radial vibration, axial position (thrust), and casing expansion measurements
• Compressors and blowers – bearing condition and shaft orbit analysis
• Pumps and fans – imbalance/misalignment checks and startup trending
• Generators and large motors – protective trips and predictive maintenance programs

A maintenance lead told me, “Swapping generic cables for the OEM 3300 XL build stabilized our readings—less drift during hot restarts,” which mirrors what I’ve seen on retrofit jobs.

Advantages & Value

• Reliability – Consistent impedance and shielding help preserve calibration and reduce nuisance trips.
• Compatibility – Drop-in with Bently Nevada 3300/3300 XL probes and Proximitor sensors; no wiring workarounds.
• Lifecycle cost – Fewer intermittent faults means fewer callouts and less unscheduled downtime.
• Technical support – We can verify dash-code options against your installed base to match lengths, armor, and connectors.

Installation & Maintenance

• Environment – Route in clean trays or conduit; avoid hot surfaces and tight bends. Maintain a gentle bend radius (typically ≥10× cable OD).
• Cabinet practice – Land the cable at the Proximitor sensor within a ventilated cabinet; keep power and transducer cabling separated to limit EMI.
• Grounding/shielding – Follow Bently Nevada grounding scheme; avoid multiple ground points that can introduce loops.
• Connections – Ensure connectors are fully seated and locked; check for any pin/chassis contamination before startup.
• Routine checks – Wipe the outer jacket, inspect strain reliefs, and verify continuity/insulation during outages. Firmware updates apply to monitors, not the cable.

Quality & Certifications

• Compliance: CE and RoHS on most configurations; ATEX/IECEx suitability when used within approved proximity transducer loops
• Safety: UL/CSA recognition is typically available for related system components
• Warranty: 12 months standard (365 days)

Related and Supporting Components

For a complete channel, pair the 330161 cable with:

• 3300 XL Proximity Probe (e.g., 330103 series, 8 mm) – for non-contact displacement measurement
• 3300/3300 XL Proximitor Sensor – signal conditioning to the monitoring system (e.g., 3500 rack or compatible monitors)

You might notice that matching the dash codes across probe, cable, and Proximitor typically keeps the transducer system within its factory spec without on-site rework. If your installed base has mixed lengths, we can review the orbit/scale factors with you.
