Turbomachinery Vibration Monitoring Solution – Bently Nevada 330904-00-14-05-01-00 | 3300 XL NSv
Where This Product Is Used
The Bently Nevada 330904-00-14-05-01-00 is a core component of the 3300 XL NSv Proximity Transducer System, engineered for continuous, non-contact shaft vibration and position measurement in rotating machinery. Typical deployment environments include:
- Steam and gas turbines in power generation plants
- Centrifugal and axial compressors in oil & gas processing
- Pumps and fans in petrochemical and refining facilities
- Gearboxes and expanders in LNG and chemical plants
- Marine propulsion and offshore platform rotating equipment
Engineers specify this transducer where API 670 compliance, high-temperature tolerance, and long-term signal stability are non-negotiable.

Why Engineers Specify This Model
- NSv Output Compatibility: The Non-Standard voltage output integrates directly with 3300 XL monitors without additional signal conditioning, reducing wiring complexity.
- High-Temperature Probe: Rated to +177°C at the probe tip — suitable for hot-section turbine bearing pedestals where standard probes fail prematurely.
- Plug-and-Play System Architecture: Probe, extension cable, and driver are factory-matched and calibrated as a system, eliminating field calibration errors.
- Long-Term Drift Stability: Bently Nevada’s proprietary coil winding and potting process ensures <1% scale factor drift over a 5-year service interval.
- API 670 Certified: Meets the machinery protection standard required by EPC contractors and end-users in oil & gas and power generation.

Application-Specific FAQ
Q: Is the 330904-00-14-05-01-00 compatible with the 3500 series monitors?
A: No. The 3300 XL NSv system is designed for 3300 XL monitor racks. For 3500 series compatibility, you need the 330900 or 350900 series transducers. Contact us to confirm the correct part for your rack.
Q: Can this transducer measure axial position as well as radial vibration?
A: Yes. With appropriate mounting (thrust collar target), the 330904 series can be used for both radial vibration and axial position measurement, subject to gap and scale factor verification.
Q: What target material is assumed for the factory calibration?
A: Factory calibration is performed on AISI 4140 steel. If your shaft material differs (e.g., Inconel, titanium), a material correction factor must be applied per Bently Nevada application note AN-028.
Q: What is the recommended gap voltage for this transducer?
A: The nominal gap voltage is –10 VDC (±0.5 V), corresponding to the midpoint of the linear measurement range. Set during commissioning with a calibrated gap tool.
Q: Do you provide a calibration certificate?
A: OEM calibration certificates are provided where available. For critical applications requiring traceable calibration, we recommend recalibration at a certified Bently Nevada service center after installation.
