Vibration Monitoring Solution – Bently Nevada 130539-50 Interconnect Cable | 3500 Series
In rotating machinery protection, signal integrity between the proximity transducer and the monitoring rack is non-negotiable. The Bently Nevada 130539-50 Interconnect Cable is the OEM-specified 50 ft coaxial extension cable engineered for the 3500 Series Machinery Protection System, delivering low-loss signal transmission in the most demanding industrial environments. When a turbine, compressor, or pump shaft deviates by even a few microns, this cable ensures that deviation is captured — accurately, reliably, every time.
Where This Product Is Used
The 130539-50 is deployed wherever Bently Nevada 3500 Series proximity systems are installed for continuous machinery health monitoring:
- Gas & Steam Turbines — shaft radial vibration and axial position monitoring at power generation facilities
- Centrifugal Compressors — rotor dynamic monitoring in petrochemical and LNG plants
- Pumps & Fans — bearing condition monitoring in water treatment and HVAC systems
- Gearboxes — high-speed shaft monitoring in paper mills and steel rolling lines
- Marine Propulsion Systems — shaft alignment and vibration monitoring on vessels
- Nuclear & Fossil Power Plants — safety-critical turbine protection loops
Wherever API 670 compliance is mandated and signal fidelity is critical, the 130539-50 is the specified interconnect solution.

Why Engineers Specify This Model
- OEM Signal Integrity — Matched impedance and capacitance characteristics preserve the eddy-current driver’s calibrated output, eliminating measurement drift caused by third-party cable substitutions.
- 50 ft Reach — Bridges the gap between field-mounted transducers and remote junction boxes or rack rooms without signal degradation.
- Harsh Environment Rated — Polyurethane jacket resists oil, moisture, and mechanical abrasion in turbine halls and compressor stations.
- API 670 Compliant System Component — Ensures the complete proximity system assembly meets the Machinery Protection Systems standard required by EPC contractors and plant operators.
- Drop-in Replacement — Identical form, fit, and function to original factory cable; no recalibration required upon installation.
- Reduced Downtime Risk — Stocking this cable as a critical spare eliminates multi-week OEM lead times during unplanned outages.

Application-Specific FAQ
Q: Can the 130539-50 be used with non-Bently Nevada monitors?
A: The cable is designed for Bently Nevada 3300 XL proximity systems. Using it with third-party monitors may affect calibration and is not recommended for API 670-compliant installations.
Q: What is the difference between 130539-50 and 330130-50-00?
A: The 130539-50 is the standard interconnect extension cable; the 330130-50-00 is a different cable assembly variant. Always verify your system drawing before ordering. Konmask’s technical team can assist with cross-referencing.
Q: Is a 50 ft cable too long for my installation? Can I get a shorter version?
A: Bently Nevada offers multiple cable lengths. Contact us with your required length and we will identify the correct part number for your application.
Q: Do you provide documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, CoC, and HS code documentation (HS: 8544.42) for all international shipments.
