Vibration Monitoring Solution – Bently Nevada 330904-00-21-10-01-00 | 3300 XL NSv Series
Where This Product Is Used
The Bently Nevada 330904-00-21-10-01-00 is a core component of the 3300 XL NSv Proximity Transducer System, engineered for continuous, non-contact vibration and position measurement in rotating machinery. It is widely deployed in:
- Steam & Gas Turbines – shaft radial vibration monitoring per API 670
- Centrifugal & Axial Compressors – real-time rotor displacement tracking in petrochemical plants
- Pumps & Fans – bearing journal orbit analysis in power generation facilities
- Gearboxes – differential expansion and eccentricity measurement
- Marine Propulsion Systems – shaft position monitoring in offshore platforms

Why Engineers Specify This Model
- NSv Output Compatibility – Designed for systems requiring non-standard voltage output, ensuring direct drop-in compatibility with legacy 3300 monitor racks without signal conditioning
- High-Temperature Stability – Maintains calibration accuracy up to 177°C, critical for hot-section turbine bearing housings
- API 670 Compliant – Meets the machinery protection standard mandated by EPC contractors and end-users in oil & gas
- Integral Cable Design – Eliminates field-splice failure points; the 5m integral cable reduces installation error in confined bearing pedestals
- Proven Platform – The 3300 XL series has over two decades of field-proven reliability in tier-1 LNG, refinery, and power generation assets

Application-Specific FAQ
Q: Is the 330904-00-21-10-01-00 compatible with the 3500 monitoring rack?
A: Yes, when paired with the appropriate 3300 XL NSv Proximitor driver (330180 series), the output is compatible with 3500/42M and 3500/45 monitor modules.
Q: What is the difference between the standard 330900 and the 330904 series?
A: The 330904 designates the metric-thread (M10 x 1) housing variant. The 330900 uses imperial threads. Verify your bearing housing thread specification before ordering.
Q: Can this transducer be used in a Zone 1 hazardous area?
A: Yes, with an approved Zener barrier (e.g., Bently Nevada 3300/20) or galvanic isolator. The transducer itself is passive; the safety rating applies to the complete loop.
Q: What target material is required for accurate calibration?
A: The factory calibration is performed on AISI 4140 steel. For other target materials (e.g., Inconel, titanium), a field recalibration or material correction factor must be applied.
Q: Does Konmask.com provide a warranty?
A: Yes. We offer a 12-month warranty against defects in materials and workmanship. OEM warranty terms apply to new, sealed units.
