Turbomachinery Vibration Monitoring Solution – Bently Nevada 330905-00-18-10-02-05 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330905-00-18-10-02-05 proximity probe is engineered for continuous, non-contact shaft vibration and position measurement in rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – Radial vibration monitoring on HP/LP rotor shafts in power generation plants
- Centrifugal Compressors – Shaft displacement measurement in petrochemical and refinery trains
- Pumps & Blowers – Bearing journal monitoring in water treatment and HVAC systems
- Gearboxes – Gear mesh and shaft orbit analysis in heavy industrial drives
- Marine Propulsion Systems – Shaft alignment and axial position monitoring
- Paper & Steel Mills – Roll and spindle vibration in continuous process lines
Wherever API 670 compliance is mandated and machine protection is critical, this probe is the field-proven choice.

Why Engineers Specify This Model
- NSv (Non-Standard voltage) Architecture – Operates with the 3300 XL 8mm driver/extension cable system, enabling direct drop-in replacement without rewiring existing 3300 series installations
- 18-inch Integral Cable – Eliminates field-spliced connections at the probe tip, reducing signal noise and failure points in high-vibration zones
- 5 mm Tip for Tight Clearances – Ideal for retrofitting into bearing housings with limited radial space, common in legacy turbine frames
- High-Temperature Stability – Maintains calibration accuracy up to 177°C, suitable for hot-section turbine bearing pedestals
- API 670 Listed – Accepted by machinery protection system auditors without additional calibration documentation

Application-Specific FAQ
Q: Is the 330905-00-18-10-02-05 compatible with the older 3300 XL 8mm system?
A: Yes. The 3300 NSv probe is backward-compatible with 3300 XL 8mm extension cables and Proximitor sensors when used with the correct driver pairing.
Q: Can this probe measure axial position as well as radial vibration?
A: Yes, with appropriate mounting orientation and a thrust position monitor card (e.g., 3500/42M), this probe can be configured for axial thrust measurement.
Q: What is the maximum gap voltage for initial setup?
A: The recommended gap voltage is -10 VDC ± 0.5 V, corresponding to approximately 50 mil (1.27 mm) gap from the target surface.
Q: Do you provide calibration certificates?
A: Calibration certificates from the original manufacturer are available upon request for units sourced through our authorized channels. Contact us before ordering to confirm availability.
Q: Can I use this probe on non-ferrous targets like aluminum or titanium?
A: Non-standard target materials require a target material correction factor. Bently Nevada provides correction curves; contact our technical team for guidance.
