Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330904-00-07-10-02-05 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330904-00-07-10-02-05 is an eddy-current proximity probe engineered for continuous, non-contact vibration and position measurement on rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – shaft radial vibration monitoring per API 670
- Centrifugal Compressors – rotor dynamic displacement measurement in petrochemical plants
- Pumps & Fans – bearing journal orbit analysis in power generation facilities
- Gearboxes – gear mesh frequency and axial position tracking
- Marine Propulsion Systems – shaft alignment verification and thrust position monitoring
- Paper & Steel Mills – roll position and vibration in high-temperature process lines
This probe is the sensing element in a complete 3300 NSv measurement chain, working in conjunction with an extension cable and a 3300 XL or 3500 series proximitor/oscillator to deliver a calibrated –24 VDC output signal.

Why Engineers Specify This Model
- Proven 3300 NSv Platform – drop-in compatible with existing 3300 XL proximitor systems; no recalibration of the monitoring rack required.
- 7 mm Tip for Tight Clearances – the 330904 body diameter fits standard API 670 probe bosses without machining modifications.
- 5 m Integral Cable – eliminates one field-splice junction, reducing signal noise and improving MTBF in high-vibration environments.
- 02-05 Connector Shell – mates directly with standard Bently Nevada extension cables (330130 series) for a sealed, moisture-resistant signal path.
- Wide Temperature Range – qualified to +177 °C, suitable for hot-section turbine bearing pedestals without additional thermal shielding.
- Non-Contact Measurement – zero mechanical wear; designed for continuous 24/7 operation across the full machinery lifecycle.

Application-Specific FAQ
Q: Is the 330904-00-07-10-02-05 compatible with the 3500 series monitoring rack?
A: Yes. The 3300 NSv probe is fully compatible with the 3500/42M Proximitor I/O module when paired with the correct 3300 XL proximitor. Verify the proximitor part number matches your rack slot configuration.
Q: Can this probe measure axial position as well as radial vibration?
A: Yes. With appropriate mounting (thrust probe bracket), the 330904 can be configured for axial position (thrust) measurement. Consult Bently Nevada application note AN-028 for installation guidance.
Q: What target material correction is needed for stainless steel shafts?
A: The standard calibration is for AISI 4140 steel. For 316 stainless steel targets, a scale factor correction of approximately –8% applies. Bently Nevada provides target material correction curves in the 3300 NSv datasheet.
Q: Is a spare probe sufficient for a hot-swap replacement?
A: Yes, provided the replacement probe is from the same calibrated system (same probe + extension cable + proximitor combination). Mixing components from different calibrated sets requires field recalibration.
Q: Do you supply the matching extension cable and proximitor?
A: Yes. Contact us with your required cable length and proximitor model to receive a matched, pre-tested measurement loop.
