Bently Nevada 330130-085-00-00 Extension Cable for 3300 XL Proximity Transducers

The Bently Nevada 330130-085-00-00 is a factory-terminated extension cable designed for the 3300 XL proximity transducer system. It maintains system accuracy by matching the impedance and capacitance required between the probe and Proximitor sensor. In many cases it’s the simplest way to extend reach in tight machines or long cable runs without sacrificing vibration data quality.

Typical users pair this cable with 5 mm or 8 mm 3300 XL probes on compressors, steam turbines, and critical pumps. From my experience, it’s picked when you need reliable shaft vibration and position signals over longer distances in harsh, oily environments.

• 3300 XL system matching – Preserves the calibrated system length and electrical characteristics for accurate eddy-current measurements.

• Length code 085 – Typically interpreted as an 8.5 m extension within the 330130 family, helping reach remote Proximitor locations.

• Robust industrial jacket – Oil- and chemical-resistant materials are commonly used on 3300 XL cables for long service life in machine housings.

• Noise-resistant construction – Shielded coax design helps minimize RFI/EMI pickup around VFDs and large motors.

• Factory terminations – Consistent, repeatable connections reduce installation variability and signal loss.

• Direct compatibility – Works with Bently Nevada 3300 XL probes and Proximitor sensors; no adapters required in standard setups.

You’ll typically see the 330130-085-00-00 on:

• Large steam and gas turbines where Proximitor racks are mounted remotely in clean cabinets.

• API 610/ISO 13709 pumps requiring reliable shaft vibration and axial position monitoring.

• Petrochemical compressors with long cable runs across hazardous or high-temperature zones.

• Balance-of-plant motors and gearboxes where electrical noise suppression is a concern.

• Measurement integrity – Maintains calibrated system length so you don’t lose accuracy in µm/mil readings.

• Lower installation risk – Factory-terminated ends usually mean fewer field splices and fewer intermittent faults later.

• Broad compatibility – Works across common 3300 XL probe families, simplifying spares and procurement.

• Total cost control – Reduces troubleshooting time and repeat work caused by non-matching third‑party cables.

• Service support – Easier to document in PM programs and align with OEM diagnostic guidance.

• Environment – Mount Proximitor modules in a ventilated cabinet; route the cable in metallic conduit or tray away from high-voltage lines when possible.

• Bend radius – Maintain a gentle bend (many sites keep ≥10× cable OD as a rule of thumb) to avoid conductor or shield stress.

• Grounding – Follow Bently Nevada grounding practices; improper shield terminations can introduce noise.

• Strain relief – Use clips or tie-downs at regular intervals to prevent vibration-induced fatigue at connectors.

• Inspection – Periodically check for jacket cuts, oil ingress, or crushed sections; replace if damage is found.

• Calibration – System verification is done at the Proximitor/output level; avoid altering total system length from the configured value.

• OEM-grade build for Bently Nevada 3300 XL systems.

• CE and RoHS conformity are typically applicable to this product class.

• Manufactured under ISO 9001 quality systems at the OEM level.

• Warranty: commonly 1 year on new units; service-exchange or expedited options can be arranged in many cases.

Quick customer note: a maintenance lead from a refinery told me they swapped a mixed-brand cable for this 330130 type and immediately saw cleaner orbit plots. That seems to be a recurring theme—matching the system length pays off in diagnostics.
