Bently Nevada 330195-02-12-05-05 – Proximity Extension Cable for 3300 XL Vibration Monitoring Systems

The Bently Nevada 330195-02-12-05-05 is a factory-terminated proximity extension cable designed for the 3300 XL proximity transducer system. From my experience, this model is typically used between the 3300 XL probe and the Proximitor Sensor to maintain the calibrated system length and preserve measurement accuracy on critical turbomachinery—compressors, steam turbines, and large motors. You might notice that the option code “-02-12-05-05” indicates a specific build configuration; the 12 usually denotes cable length (approx. 12 ft), making it a straightforward drop-in when you need a standard run without splices or guesswork.

Key Features

• Matched system length – Helps maintain the calibrated distance for the 3300 XL proximity transducer system, supporting accurate shaft vibration and position measurements.
• Factory-terminated connectors – Reduces installation time and, in many cases, avoids field termination errors that can skew readings.
• Rugged, shielded coax design – Typically provides strong noise immunity in electrically noisy environments around VFDs and switchgear.
• Backwards compatibility – Commonly used with 3300 XL 5 mm/8 mm probes and Proximitor Sensors, simplifying spares management across sites.
• Temperature-tolerant build – Suitable for standard industrial temperature ranges; high-temp variants exist when needed.
• Traceable option code – The “-02-12-05-05” option string helps you match engineering standards and replacement rules without re-qualification.

Technical Specifications

Application Fields

This cable is widely used in condition monitoring loops where stable proximity signals are essential: steam and gas turbines, centrifugal compressors, critical pumps and blowers, and large synchronous or induction motors. One thing I appreciate is how consistently it behaves in mixed cabinets with VFD noise; in most cases the shielding keeps the waveform clean enough that your 3500 rack doesn’t need extra filtering.

Advantages & Value

• Reliability: Factory-terminated, repeatable performance—less drift caused by questionable field splices.
• Compatibility: Plays nicely with established 3300 XL setups, so spares stocking is simpler across plants.
• Cost Savings: Faster install and fewer retests after outages; typically reduces commissioning time on turnarounds.
• Supportability: Easy to audit option codes against P&IDs and machine protection drawings.

A maintenance supervisor shared with us that swapping in this exact length variant restored their shaft orbit plots without rebalancing—seems to be the benefit of keeping the original transducer system length intact.

Installation & Maintenance

• Environment: Install in a clean, dry cabinet or conduit; avoid liquid ingress and high EMI paths near switching devices.
• Routing: Keep a gentle bend radius (typically ≥25 mm) and support the cable to prevent mechanical strain at connectors.
• Connections: Seat connectors fully on the probe and Proximitor ends; do not over-torque. No splices unless explicitly allowed by your site standard.
• Verification: After replacement, perform a DC gap check and linearity check. If system length changed, recalibrate per Bently Nevada procedure.
• Routine Care: Inspect for abrasion or crush marks during outages; clean connector threads; confirm cable continuity if trending shows unexpected bias shifts.
• Safety: Lock out the machine as required; route away from rotating parts and hot surfaces where possible.

Quality & Certifications

• Certifications: CE, RoHS; ATEX/CSA/IECEx variants may be available depending on the option code.
• Manufacturer Standards: Built for use with Bently Nevada 3300 XL systems and typical industrial environments.
• Warranty: 365 days (our supply terms).

Note: Exact temperature rating, connector style, and approvals can vary by option code. If you’re matching an installed base, sharing a photo of the cable tags or the full BOM usually speeds up cross-checking.
