- Pumps & Fans — bearing journal displacement tracking in power generation and water treatment facilities
- Gearboxes — axial thrust and radial vibration surveillance in heavy industrial drivetrains
- Electric Motors (>1 MW) — shaft centerline monitoring in steel mills and mining operations
- Marine Propulsion Systems — continuous condition monitoring on vessel main shafts
This probe is fully compatible with Bently Nevada 3300 series monitoring systems and is a direct fit for installations requiring NSv-rated signal conditioning.

Why Engineers Specify This Model
- NSv Signal Compatibility — Designed for systems requiring non-standard voltage output, ensuring direct interoperability with legacy and current 3300-series Proximitor® drivers without signal conditioning adapters.
- Wide Thermal Envelope — Rated to +177 °C, making it suitable for hot-section turbine bearing pedestals where standard probes fail prematurely.
- High Frequency Bandwidth — DC–10 kHz response captures both slow-roll runout and high-frequency subsynchronous instabilities critical for compressor surge detection.
- Matched System Calibration — Factory-calibrated as a probe + extension + Proximitor® set, eliminating field calibration errors that compromise API 670 compliance.
- Armored Cable Construction — Stainless steel braid over PTFE insulation resists oil, steam, and chemical exposure in harsh plant environments.
- Drop-in Replacement — Identical mechanical envelope and connector to predecessor models; no bracket modification required during maintenance turnarounds.

Application-Specific FAQ
Q: Can this probe be used with a 3500-series monitor?
A: Yes. The 330905-00-10-10-02-05 is electrically compatible with 3500-series monitors when paired with the correct Proximitor® driver. Verify the gap voltage window matches your monitor card configuration.
Q: What is the difference between NSv and standard 3300 probes?
A: NSv (Non-Standard Voltage) probes are calibrated for a different output voltage range compared to standard 3300 probes. They must be used with NSv-rated Proximitor® drivers. Mixing standard and NSv components will result in incorrect scale factor and false alarms.
Q: Is field recalibration required after replacement?
A: Factory-matched probe/extension/Proximitor® sets do not require field recalibration if all three components are replaced as a set. If only the probe is replaced, a gap voltage verification and scale factor check per API 670 Annex D is recommended.
Q: What shaft materials are compatible?
A: The probe is factory-calibrated for AISI 4140 steel. For stainless steel, Inconel, or titanium shafts, a material-specific calibration curve must be applied. Contact us for calibration data sheets for non-standard target materials.
Q: Can this probe operate in a hydrogen-cooled generator environment?
A: The probe itself is rated for the temperature range, but the complete measurement loop (including Proximitor® and cabling) must be assessed for hydrogen atmosphere compatibility. Consult your safety engineer and the applicable IEC 60079 zone classification.
Q: Do you offer exchange/repair services?
A: We currently offer new-unit supply only. For repair or recertification of existing probes, contact Bently Nevada’s authorized service network directly.
