Bently Nevada 330130-45-00-05 Extension Cable | 3300 Series Eddy Current Sensor System
Engineering Background
The Bently Nevada 330130-45-00-05 is a precision-engineered extension cable designed exclusively for use within the Bently Nevada 3300 Series eddy current proximity sensor system — one of the most widely deployed vibration and position monitoring platforms in rotating machinery applications worldwide. This cable serves as the critical signal-transmission link between the proximity probe and the proximitor/driver module, maintaining signal integrity across demanding industrial environments.
Product Positioning
Targeted at reliability engineers, rotating equipment specialists, and MRO procurement teams, the 330130-45-00-05 is the OEM-specified 4.5-meter (approximately 15-foot) armored extension cable for the 3300 Series. It is the preferred replacement and spare-parts choice for facilities operating gas turbines, steam turbines, compressors, pumps, and other critical rotating assets where continuous vibration monitoring is mandatory.

Proven Application Environments
- Gas & Steam Turbines — Shaft radial vibration and axial position monitoring on critical turbine trains
- Centrifugal Compressors — Continuous proximity measurement for API 670-compliant machinery protection systems
- Pumps & Motors — Bearing journal orbit and eccentricity monitoring in high-speed rotating equipment
- Gearboxes — Gear mesh frequency and shaft displacement tracking
- Petrochemical & Refining Plants — Hazardous-area installations requiring robust, armored cable routing
- Power Generation — Baseload and peaking plant turbine-generator sets
- Marine & Offshore Platforms — Vibration monitoring in salt-spray and high-humidity environments
Engineering Advantages
- OEM Signal Integrity — Manufactured to Bently Nevada’s exact impedance and capacitance specifications; eliminates measurement error introduced by non-OEM cables
- Armored Construction — Stainless steel braid armor provides mechanical protection against abrasion, crushing, and rodent damage in plant environments
- Wide Temperature Tolerance — Rated from -40 °C to +121 °C, suitable for both cryogenic and high-temperature process areas
- Drop-in Replacement — Plug-and-play compatibility with all 3300 Series probes and proximitor drivers; no recalibration required
- API 670 Compliance Support — Enables machinery protection systems to meet API 670 (5th Edition) requirements for critical and essential machinery
- Reduced Downtime Risk — Stocking this cable as a critical spare eliminates extended lead-time exposure during unplanned outages
System Architecture & Signal Flow
The 3300 Series eddy current system operates as a three-component signal chain:
- Proximity Probe (e.g., 330103, 330104, 330105) — Generates the high-frequency eddy current field at the shaft surface
- Extension Cable 330130-45-00-05 — Transmits the modulated RF signal from probe tip to proximitor with minimal loss over 4.5 m
- Proximitor / Driver Module (e.g., 3300 XL Proximitor) — Demodulates the signal and outputs a DC voltage proportional to gap distance (typically -18 VDC system)
The total system cable length (probe integral cable + extension cable) must be matched to the proximitor’s calibrated range. The 330130-45-00-05 is factory-calibrated for use in standard 5 m and 9 m total-length system configurations.

Technical FAQ
Q: Can the 330130-45-00-05 be used with non-Bently Nevada proximitors?
A: No. This cable is impedance-matched and calibrated specifically for the Bently Nevada 3300 Series proximitor. Use with third-party drivers will result in measurement errors and may void system certification.
Q: What is the difference between the 330130-45-00-00 and 330130-45-00-05?
A: The last two digits denote the connector/termination option. The -05 suffix specifies the standard BNC termination for the 3300 Series. Confirm your proximitor input connector type before ordering.
Q: Is this cable suitable for hazardous area (ATEX / IECEx) installations?
A: The 3300 Series system including this extension cable is designed for use in hazardous areas when installed per Bently Nevada’s system documentation and applicable local electrical codes. Consult the system safety manual for zone classification requirements.
Q: What is the lead time for out-of-stock units?
A: Typical lead time for sourced units is 2–4 weeks. Contact us for expedited sourcing options.
Q: Do you provide a warranty?
A: Yes. New units carry the original manufacturer warranty. Surplus and refurbished units carry a 90-day Konmask functional warranty.
