Bently Nevada 330104-00-03-50-02-05 8mm Proximity Transducer System – 3300 XL Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, and unplanned shutdowns that cost industrial facilities tens of thousands of dollars per hour. Without a reliable proximity transducer system in place, operators are flying blind — unable to detect the early warning signs that separate a controlled maintenance stop from a full-scale mechanical failure. The Bently Nevada 330104-00-03-50-02-05 is the component that stands between normal operation and disaster.
Within the 3300 XL Series — Bently Nevada’s industry-defining platform for machinery protection — the 330104-00-03-50-02-05 occupies a precise technical niche: an 8 mm eddy-current proximity transducer system engineered for high-accuracy, non-contact measurement of radial shaft vibration and axial position. The 3300 XL platform is deployed across thousands of turbines, compressors, pumps, and gearboxes worldwide, and this specific configuration (probe + extension cable + proximitor) is one of the most widely specified assemblies in API 670-compliant machinery protection systems globally.

Key Features & Benefits
- Complete Matched System: Probe, extension cable, and proximitor are factory-matched and calibrated as a unit — eliminating field calibration errors that plague mix-and-match assemblies.
- 8 mm Eddy-Current Technology: Provides superior sensitivity for small-diameter shaft applications where larger probes cannot be physically accommodated.
- API 670 Compliant: Meets the international standard for machinery protection systems, ensuring acceptance by EPC contractors, insurance auditors, and plant safety reviews.
- Drop-in Replacement: Direct OEM-equivalent replacement for existing 3300 XL installations — no rewiring, no reconfiguration of monitors required.
- High Signal Integrity: Shielded cable construction minimizes electromagnetic interference in electrically noisy industrial environments (VFD-heavy plants, substations).
- Long Service Life: Solid-state, non-contact design with no moving parts — designed for continuous 24/7 operation in harsh industrial conditions.
Industry & Equipment Applications
- Oil & Gas: Centrifugal compressors, gas turbines, steam turbines on upstream/midstream/downstream facilities
- Power Generation: Steam and gas turbine-generators, boiler feed pumps, induced draft fans
- Petrochemical & Refining: Reactor charge pumps, cracked gas compressors, process gas blowers
- LNG Plants: Main refrigerant compressor trains requiring continuous vibration surveillance
- Marine & Offshore: Platform compressors and turbines requiring API 670 compliance
- General Industry: High-speed gearboxes, large centrifugal pumps, critical rotating equipment requiring condition monitoring
System Integration & Compatible Parts
The 330104-00-03-50-02-05 is designed to integrate directly with the Bently Nevada 3300 XL monitoring system architecture. Compatible system components include:
- 3300 XL Series Monitors (radial vibration, axial position, speed)
- 3500 Series Machinery Protection System (with appropriate interface modules)
- System 1® Condition Monitoring Software
- Bently Nevada 3300 XL extension cables (matched impedance)
- Proximitor® Sensor housings and junction boxes
When replacing or expanding an existing installation, always verify the complete system part numbers (probe + cable + proximitor) to ensure matched-system calibration is maintained.
