Bently Nevada 330130-045-12-00 – Extension Cable for 3300 XL Proximity Transducer Systems

The Bently Nevada 330130-045-12-00 is, in most cases, specified as a 3300 XL series extension cable used between 5 mm/8 mm proximity probes (such as 330103/330104) and their matching 3300 XL Proximitor sensors. If you’re maintaining turbines, compressors, large motors, or gearboxes, this cable forms the middle link that preserves calibration accuracy and low-noise transmission from the probe tip back to the monitor rack.

One thing I appreciate is how consistent the 3300 XL cabling tends to be in real installations—when the length and part code match your probe and Proximitor, the system typically holds the 200 mV/mil (7.87 mV/μm) system sensitivity and phase characteristics you’re expecting. The “045” length code is commonly interpreted as approximately 4.5 meters, which seems to be a very practical run length inside many machine trains and cabinets. The “12-00” optioning usually relates to connector or protection selections; if you’re matching existing plant spares, we can help verify those details against your historical BOMs.

Key Features

• Purpose-built for 3300 XL systems – Connects 330103/330104 probes to matching Proximitor sensors, maintaining system accuracy.
• Length code “045” – Typically denotes ~4.5 m, a common distance for machinery skids and proximity runs.
• Low-noise transmission – Shielded construction to reduce electrical interference in industrial environments.
• Rugged, installation-ready – Designed for cabinet routing and cable trays; works well with standard clamps and conduit.
• Compatibility-minded – Generally supports 5 mm and 8 mm 3300 XL probes and Proximitor sensors used across API 670-style monitoring setups.
• Service-friendly – Clear coding helps match spare parts on site; easy replacement during scheduled shutdowns.

Technical Specifications

Application Fields

From my experience, this model shows up wherever serious vibration monitoring is required:

• Steam and gas turbines – radial/axial position measurements on bearings and seals
• Centrifugal compressors – probe runs from bearing housings to skids
• Large motors, pumps, and gearboxes – standard 3300 XL transducer loops
• Refining, petrochemical, and power generation plants – API 670-style monitoring architectures

Advantages & Value

• Reliability under noise – Shielding and proven 3300 XL construction help keep signals clean in high-EMI areas.
• Calibration integrity – Matching lengths and part coding preserve the system’s sensitivity/phase, reducing rework.
• Compatibility assurance – Pairs well with installed 330103/330104 probes and Proximitor sensors, limiting scope creep during turnarounds.
• Lower lifecycle cost – Fewer nuisance trips and less troubleshooting time when cables match OEM specs.
• Technical support – We can help confirm length/option codes against your tag list before shipment, which typically speeds commissioning.

Installation & Maintenance

• Environment – Install in dry, ventilated cabinets or protected trays; avoid tight bends (respect minimum bend radius).
• Routing – Separate from high-voltage power cables; use metal conduit or shielded trays where possible to limit EMI.
• Connections – Mate connectors firmly at the probe and Proximitor ends; check locking features and strain relief.
• Safety – De-energize the monitoring loop before handling; verify grounding of shields per plant standard.
• Routine checks – Inspect for abrasion or crushing; clean connectors; verify loop readings after shutdowns or cable replacement.
• Firmware/calibration – When replacing cabling, it’s good practice to reconfirm channel calibration at the monitor (many teams do this during planned outages).

Quality & Certifications

The 3300 XL transducer family is widely deployed in regulated industries and typically aligns with CE and RoHS requirements for cabling of this type. UL or other marks may apply at the system level rather than the cable alone, so we usually check job-by-job. Warranty coverage on this item is 365 days.

A maintenance supervisor at a gas plant told us last quarter, “Swapping in the correctly coded 330130 cable stabilized our axial position readings right away.” That’s the kind of predictable result most teams look for during short turnarounds.
