Vibration Monitoring Solution – Bently Nevada 330903-00-11-05-02-05 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330903-00-11-05-02-05 is a 3300 NSv Series eddy-current proximity probe engineered for continuous, non-contact shaft vibration and position measurement in rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – radial vibration and axial position monitoring on high-speed shafts
- Centrifugal Compressors – real-time rotor orbit tracking in petrochemical and LNG plants
- Pumps & Fans – bearing-housing displacement measurement in power generation and water treatment
- Gearboxes – gear-mesh frequency analysis and shaft eccentricity detection
- Marine Propulsion Systems – shaft alignment verification and thrust-bearing wear monitoring

Why Engineers Specify This Model
- Non-contact measurement eliminates mechanical wear and extends sensor service life beyond 10 years in continuous operation
- High-frequency response (DC–10 kHz) captures sub-synchronous instabilities, oil whirl, and rub events that accelerometers miss
- NSv calibration curve provides a tighter scale-factor tolerance (±1%) for API 670-compliant machinery protection systems
- 5 m integral cable reduces field-junction connection points, lowering noise floor and installation time
- Drop-in replacement for legacy 3300 XL probes – same mounting thread, same connector, same driver compatibility

Application-Specific FAQ
Q: Is the 330903-00-11-05-02-05 compatible with the 3500/42M monitor?
A: Yes. The 3300 NSv probe is fully compatible with the 3500/42M Proximitor/Seismic Monitor when paired with the correct NSv Proximitor driver. Verify the driver part number ends in “-NSv” to ensure matching calibration curves.
Q: Can this probe measure axial position as well as radial vibration?
A: Yes. With appropriate mounting (thrust-collar target), the 330903-00-11-05-02-05 can be configured for axial position measurement within its 0.25–2.25 mm linear range.
Q: What target material correction is needed for stainless steel shafts?
A: Stainless steel (e.g., 316L) requires a target material correction factor. Consult Bently Nevada Application Note AN-028 or contact our technical team for a corrected scale factor.
Q: Do you offer calibration certificates?
A: Calibration certificates from accredited labs can be arranged for an additional fee. Please specify at time of order.
Q: What is the minimum order quantity?
A: Single units are available. Volume pricing applies at 5, 10, and 25+ units.
