Bently Nevada 330130-045-01-05 Extension Cable – Reliable Link for 3300 XL Proximity Probe Systems

The Bently Nevada 330130-045-01-05 is a 4.5 m 3300 XL extension cable designed to connect a 3300 XL proximity probe to its Proximitor sensor. One thing I appreciate is how consistent it is across harsh environments—typically rated for wide temperatures and built with an industrial FEP jacket. If you’re building or maintaining an API 670-compliant vibration/position monitoring loop, this cable keeps the signal chain stable and predictable.

• Purpose-built for 3300 XL systems: Creates the probe-to-Proximitor link for eddy-current vibration and axial position measurements.

• Nominal 4.5 m length: The “045” code typically indicates 4.5 meters, useful when fine-tuning total transducer system length (5, 7, 9 m, etc.).

• Factory-molded ClickLoc connectors: Secure mating that resists loosening from machinery vibration; you typically feel a positive detent when it’s seated.

• Industrial FEP outer jacket: Blue, chemically resistant, and proven in refineries, power plants, pulp & paper—places where oils and heat are common.

• Stable signal performance: Controlled cable characteristics help maintain calibration and linearity when paired with the correct probe and Proximitor.

• System compatibility: Works with Bently Nevada 3300 XL 5 mm/8 mm probes and Proximitor sensors; commonly used with 3500 and 1900 series monitoring racks.

From my experience, this cable sees the most action in rotating equipment where reliability is non-negotiable. Typical installations:

• Steam/gas turbines and large compressors monitored by 3500 racks

• Pumps and fans in chemical, refining, and power generation units

• Paper machine rolls and calendaring lines (axial/shaft position)

• Gearboxes and high-speed motors in steel and mining plants

One maintenance lead at a steel mill told us they swapped to this exact length to clean up probe calibration—seems to be the sweet spot when the probe had to be rerouted through a tight enclosure.

• High reliability under vibration: ClickLoc prevents gradual loosening that you might see with generic connectors.

• System-level compatibility: Maintains the calibrated transducer length so you don’t chase drift on the monitor cards.

• Lower lifecycle cost: Durable jacket and stable characteristics reduce unplanned change-outs and re-calibration hours.

• Procurement simplicity: Clear length and option codes; easy to standardize spares for site-wide 3300 XL loops.

• Supportable across industries: Common part across turbines, compressors, and API 670 programs—spares are predictable.

• Cabinet and routing: Run in grounded metallic conduit or cable tray where practical; keep separation from high-voltage or VFD power cables.

• Bend radius: Maintain a gentle bend; in most cases a minimum radius around 25 mm is a safe practice for small coax.

• Connector handling: Keep ends clean/dry; mate until the ClickLoc detent engages—do not over-torque.

• Environmental sealing: Use boots or glands at panel entries; avoid standing liquid in junction boxes.

• Verification: After installation, confirm total transducer system length in the maintenance record (probe + extension); re-verify linearity if lengths changed.

• Routine checks: During outages, inspect for abrasion or crushed sections; wipe down with lint-free cloth; no field re-termination (factory-molded).

• Firmware/monitoring: If monitor scaling was tuned for a different cable length, update the rack configuration and run a quick calibration check.

• Compliance: CE and RoHS alignment for cable materials; often used in API 670-compliant systems when paired with 3300 XL hardware.

• Hazardous areas: ATEX/IECEx options are typically available at the system level (probe + extension + Proximitor); verify specific markings on your order code.

• Warranty: Manufacturer’s limited warranty applies; most users treat these as critical spares with clear lot traceability.

• Traceability: Part number and length code on labels for maintenance records and easy reorder.

If you’re matching this 330130-045-01-05 to an existing probe, I’d suggest confirming the installed probe length first—getting the total system length right avoids recalibration headaches later.
