2789-144 — Bently Nevada 3300 XL 8mm Extension Cable (144-Inch Lead) | Original Spare Parts

As a procurement manager sourcing critical rotating machinery components, you need parts that arrive verified, documented, and ready to install — no surprises. The Bently Nevada 2789-144 is a factory-original extension cable purpose-built for the 3300 XL 8mm proximity probe system, one of the most trusted eddy-current sensing platforms deployed across global turbomachinery fleets. This unit is 100% Brand New and Factory Sealed, sourced through verified OEM supply channels, and ships with full traceability documentation. The complete model number 2789-144 identifies a 144-inch ( 3.66 m) lead length — a specification that must never be abbreviated or substituted when ordering for calibrated measurement chains.

Industrial facilities operating steam turbines, centrifugal compressors, and critical pumps rely on the 2789-144 to bridge the gap between the proximity probe and the Proximitor® sensor while preserving the calibrated gap-voltage curve. Whether you are maintaining an active PLC System or replacing end-of-life components in a legacy DCS or SIS architecture, this Original New spare part eliminates the risk of signal drift caused by counterfeit or non-OEM cables. Target industries include Oil & Gas, Power Generation, Petrochemical, and Marine — any sector where unplanned downtime carries six-figure hourly costs. Fast Global Shipping is available from verified stock.

Backed by a 12-month warranty and full technical support, the 2789-144 is the procurement-safe choice for engineers who cannot afford calibration errors in their vibration monitoring loops. Contact our team today for a formal quotation and lead-time confirmation.

Technical Specifications & Selection Guide

Selection Note: The 3300 XL 8mm sensing chain is a three-component assembly: probe + extension cable + Proximitor® sensor. Total system cable length must match the Proximitor® model’s calibrated range. The 2789-144 is specified for installations requiring a 144-inch extension segment. Always confirm the Proximitor® datasheet before ordering.

Core Features & Technical Advantages

• Complete OEM Part No. 2789-144 — guaranteed drop-in compatibility with Bently Nevada 3300 XL 8mm probe assemblies; no re-calibration required
• 100% Original and Brand New — factory-sealed with full OEM traceability; eliminates counterfeit risk in safety-critical SIS and DCS loops
• Precision Low-Loss Coaxial Construction — maintains calibrated gap-voltage linearity across the full 10 VDC measurement range
• Robust Double-Shield Architecture — heavy-duty EMI/RFI rejection engineered for motor control centers, switchgear rooms, and high-frequency drive environments
• 144-Inch (3.66 m) Reach — resolves remote Proximitor® mounting challenges without signal attenuation or impedance mismatch
• EOL Legacy System Support — a direct Control Module replacement for aging 3300 XL installations where OEM parts are no longer available through standard distribution

Typical Application Scenarios

✅ Oil & Gas — Upstream & Midstream Compression: Centrifugal compressor trains in gas processing plants require precise axial position and radial vibration data. When the Proximitor® is mounted remotely from the bearing housing due to high-pressure casing geometry, the 2789-144 provides the exact extension length needed without compromising the calibrated measurement chain.

Power Plants — Steam & Gas Turbines: Shaft radial vibration monitoring on large turbine-generator sets demands uninterrupted signal integrity. The 2789-144 is routinely specified for turbine bearing pedestals where cable routing paths exceed standard 1-meter probe cable lengths, ensuring the PLC System and DCS receive clean, accurate vibration signals.

✅ Petrochemical — Reactor Agitators & Pumps: High-temperature, chemically aggressive environments degrade non-OEM cables rapidly. The factory-sealed 2789-144 withstands oil mist, steam, and solvent exposure, making it the preferred Industrial Automation spare part for planned maintenance shutdowns.

✅ Marine & Offshore Platforms: Salt-spray and humidity accelerate corrosion in cable connectors. The double-shielded coaxial construction of the 2789-144 maintains signal fidelity in offshore environments where replacement logistics are costly and downtime is unacceptable.

✅ Gearboxes & Rotating Machinery — General Industry: Multi-stage gearboxes with complex internal cable routing benefit from the 144-inch extension reach, enabling eccentricity and differential expansion measurements without improvised cable splices that introduce impedance discontinuities.

FAQ — Frequently Asked Questions

Q: What is the price of the Bently Nevada 2789-144, and do you offer volume discounts?
A: Pricing for the 2789-144 is listed on this page and reflects current OEM market rates for 100% Original and Brand New units. Volume discounts are available for orders of 3 or more units. Contact sale@ninermas.com with your required quantity and delivery schedule for a formal quotation. We regularly support MRO procurement teams and EPC contractors with competitive pricing on Bently Nevada Spare Parts.

Q: Is the 2789-144 compatible with all Bently Nevada 3300 XL 8mm Proximitor® models?
A: Yes. The 2789-144 uses standard BN coaxial connectors and is calibrated for the 3300 XL 8mm probe family. It is compatible with all standard 3300 XL Proximitor® models. Always verify the total system cable length against your specific Proximitor® datasheet to confirm the 144-inch extension is appropriate for your installation.

Q: Can you provide a Certificate of Origin or OEM documentation for customs and quality audits?
A: Absolutely. All units are supplied with a Certificate of Conformance confirming 100% Original and Brand New status. Country of Origin documentation (United States) and original Bently Nevada packaging are included. Additional quality records can be provided upon request for ISO-certified facilities and regulated industries.

Q: Where can I download the datasheet for the Bently Nevada 2789-144?
A: The official datasheet for the 3300 XL 8mm Extension Cable series is available from Bently Nevada (Baker Hughes). Contact our technical team at sale@ninermas.com and we will provide the relevant documentation, including installation guidelines and system length compatibility tables, as part of our pre-sales engineering support.

Q: Can this cable be used to replace a damaged extension cable in an existing 3300 XL installation without re-calibrating the Proximitor®?
A: Yes — provided the replacement 2789-144 matches the original cable’s length specification. Because this is an Original New OEM unit with identical electrical characteristics, no re-calibration of the Proximitor® is required. Simply replace the damaged cable, verify the gap voltage at the nominal probe position, and confirm the output falls within the calibrated linear range.
