Bently Nevada 330903-00-12-10-02-05/CN Proximity Probe – 3300 NSv Series
When a proximity probe fails mid-operation on a critical turbine or compressor train, the consequences are immediate and severe: unplanned shutdowns, loss of vibration data integrity, and potential catastrophic rotor damage. Continuous shaft monitoring is not optional in high-speed rotating machinery — it is the last line of defense. The Bently Nevada 330903-00-12-10-02-05/CN is engineered to eliminate that risk, delivering uninterrupted, high-accuracy eddy-current displacement sensing in the most demanding industrial environments.
Within the Bently Nevada 3300 NSv (Non-Standard Voltage) Series, the 330903-00-12-10-02-05/CN occupies a precision-engineered niche: a 25 mm diameter probe body with a 300 mm armored cable, optimized for installations where standard voltage outputs must be adapted to site-specific signal conditioning requirements. This series is globally recognized as the benchmark for OEM-compatible proximity sensing in power generation, oil & gas, and petrochemical industries.

Key Features & Benefits
- OEM-Grade Accuracy: Manufactured to Bently Nevada’s original design tolerances, ensuring drop-in compatibility with existing 3300 NSv Proximitor® systems without recalibration.
- Armored Cable Construction: The 300 mm armored cable provides mechanical protection against vibration fatigue, oil splash, and abrasion in harsh machinery enclosures.
- Non-Standard Voltage Output: The NSv designation allows integration into legacy or custom signal conditioning architectures where standard ±24 VDC outputs are not suitable.
- High-Temperature Tolerance: Rated for continuous operation up to 177°C at the probe tip, suitable for hot-section turbine bearing pedestals.
- Minimal Maintenance: Solid-state eddy-current technology has no moving parts, delivering multi-year service life with no scheduled maintenance intervals.
- Direct System Replacement: Plug-and-play replacement for failed or end-of-life 330903-series probes in existing Bently Nevada monitoring systems.
Industry & Equipment Applications
- Power Generation: Steam turbines, gas turbines, and generator shaft radial vibration monitoring.
- Oil & Gas: Centrifugal compressors, expanders, and pipeline booster pump trains.
- Petrochemical & Refining: Reactor feed pumps, cracked gas compressors, and critical rotating equipment per API 670.
- Marine Propulsion: Shaft monitoring on large diesel and gas turbine marine drives.
- Pulp & Paper / Steel Mills: High-speed roll drives and induced draft fan monitoring.
System Integration & Compatible Parts
