Rotating Machinery Vibration Monitoring Solution — Bently Nevada 330909-00-20-10-02-CN | 3300 XL NSv Series
Where This Product Is Used
The Bently Nevada 330909-00-20-10-02-CN is a high-precision eddy-current proximity transducer engineered for continuous, non-contact vibration and position measurement on rotating machinery. It is routinely specified in the following industrial environments:
- Steam & Gas Turbines — shaft radial vibration, thrust position, and differential expansion monitoring in power generation plants
- Centrifugal & Axial Compressors — real-time rotor orbit and bearing clearance measurement in petrochemical and LNG facilities
- Pumps & Fans — critical rotating equipment protection in water treatment, HVAC, and process industries
- Gearboxes & Expanders — high-speed shaft monitoring where contact sensors are impractical
- Marine Propulsion Systems — shaft alignment and vibration surveillance on vessel drive trains
Wherever API 670 machinery protection is mandated, the 3300 XL NSv system is the benchmark solution trusted by reliability engineers worldwide.

Application-Specific FAQ
Q: Is the 330909-00-20-10-02-CN compatible with the Bently Nevada 3500 rack?
A: Yes. When paired with the correct 3300 XL 8mm Proximitor driver and extension cable, this transducer integrates directly with the 3500/40M and 3500/42M I/O modules.
Q: What does the “-CN” suffix indicate?
A: The CN suffix denotes the China-market connector variant, factory-terminated for local installation standards. It is electrically identical to the standard variant but uses a CN-style connector body.
Q: Can this transducer be used on non-ferrous targets?
A: The standard calibration is optimized for AISI 4140 steel. For non-ferrous targets (aluminum, titanium, Inconel), a target material correction factor must be applied. Contact our technical team for guidance.
Q: What is the difference between the 330909 and 330905 series?
A: The 330909 is the 8mm NSv variant; the 330905 is the standard 5mm probe. They are not interchangeable — verify your existing system’s probe diameter before ordering.
Q: Do you provide calibration certificates?
A: A certificate of conformance is included. NIST-traceable calibration certificates can be arranged upon request for an additional fee.
