Vibration Monitoring Solution – Bently Nevada 330903-00-11-05-02-CN | 3300 XL NSv Extension Cable
The Bently Nevada 330903-00-11-05-02-CN is a factory-specification NSv (Non-Standard voltage) Extension Cable engineered for the 3300 XL Proximity Transducer System. It bridges the gap between the proximity probe and the proximitor/monitor, maintaining signal integrity in high-vibration, high-temperature industrial environments where continuous shaft and rotor monitoring is mission-critical.
Where This Product Is Used
This extension cable is specified by rotating machinery engineers and reliability teams across the following industries and applications:
- Oil & Gas – Turbomachinery: Compressor trains, gas turbines, and centrifugal pumps on offshore platforms and onshore processing facilities where API 670 compliance is mandatory.
- Power Generation: Steam turbine shaft eccentricity and radial vibration monitoring in coal-fired, gas-fired, and nuclear power plants.
- Petrochemical & Refining: Reactor agitators, boiler feed pumps, and critical rotating equipment requiring continuous online condition monitoring.
- LNG & Pipeline: High-speed centrifugal compressors and expanders where unplanned downtime carries multi-million-dollar consequences.
- Marine & Offshore: Propulsion shaft monitoring and auxiliary machinery protection systems.
- Pulp & Paper / Mining: Large fan drives, ball mills, and kiln drives with harsh ambient conditions.

Application-Specific FAQ
Q: Is the 330903-00-11-05-02-CN compatible with the older 3300 (non-XL) series?
A: No. The NSv extension cable is specifically designed for the 3300 XL NSv transducer chain. Using it with the standard 3300 series will result in incorrect gap voltage and measurement errors. Verify your proximitor model before ordering.
Q: Can this cable be cut to a custom length in the field?
A: No. The 3300 XL system is calibrated as a matched set (probe + extension cable + proximitor). Cutting or splicing the extension cable will alter the system’s electrical characteristics and invalidate calibration. Always order the correct length suffix.
Q: What does the “-CN” suffix indicate?
A: The “-CN” suffix designates the country of manufacture (China) for customs and traceability purposes. The electrical and mechanical specifications are identical to the standard part.
Q: Do you provide a Certificate of Conformance (CoC)?
A: Yes. A CoC can be provided upon request for quality-critical installations. Please specify this requirement when placing your order.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 piece. Volume pricing is available for orders of 5 pieces or more — contact us for a tiered price schedule.
