Turbine Vibration Monitoring Solution – Bently Nevada 330903-00-06-10-02-05/CN | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330903-00-06-10-02-05/CN is an 8 mm eddy-current proximity probe engineered for continuous, non-contact vibration and shaft position measurement in critical rotating machinery. Proven deployment environments include:
- Steam & Gas Turbines – radial shaft vibration monitoring on power generation units rated from 10 MW to 1 GW
- Centrifugal Compressors – real-time rotor displacement in petrochemical, LNG, and refinery trains
- Pumps & Fans – bearing journal orbit analysis in water treatment, HVAC, and process industries
- Gearboxes – axial thrust position monitoring to detect misalignment and progressive wear
- Marine Propulsion Systems – shaft monitoring in shipboard machinery and offshore platforms
- Paper & Steel Mills – roll and spindle vibration measurement in high-humidity environments
This probe is a direct-fit replacement for existing 3300 NSv and 3300 XL 8 mm installations and is fully compatible with Bently Nevada 3300 series monitors and Proximitor® drivers.

Application-Specific FAQ
Q: What does the /CN suffix mean?
A: The /CN suffix designates China as the country of manufacture. The probe is functionally identical to the standard 330903-00-06-10-02-05 in all performance specifications.
Q: Can this probe connect directly to a 3500 series monitor?
A: No. A Proximitor® driver (e.g., 330180 or 330185) is required between the probe and the 3500 monitor input card.
Q: What is the maximum shaft speed this probe can monitor?
A: The 3300 NSv system is rated for shaft speeds up to 100,000 RPM, making it suitable for high-speed turbomachinery including gas turbines and turboexpanders.
Q: Is calibration required after installation?
A: Gap setting (typically 1.0–1.5 mm / 40–60 mil) must be verified during installation. The probe-driver pair is factory-calibrated and does not require electronic recalibration when replacing a matched system.
Q: Do you ship internationally?
A: Yes. We ship globally via DHL, FedEx, and UPS Express. Contact us for a freight quote to your destination.
Q: Can I order a complete loop kit (probe + cable + driver)?
A: Yes. Contact [email protected] with your application details and we will quote a matched, tested loop assembly.
