Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330908-00-16-10-02-05 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330908-00-16-10-02-05 proximity probe is engineered for continuous, non-contact vibration and position measurement in critical rotating machinery environments. Typical deployment sites include:
- Steam & Gas Turbines — shaft radial vibration monitoring per API 670
- Centrifugal Compressors — rotor dynamic displacement measurement in petrochemical plants
- Pumps & Fans — bearing journal orbit analysis in power generation facilities
- Gearboxes — gear mesh frequency and eccentricity detection
- Marine Propulsion Systems — shaft alignment and axial position monitoring
- Hydro Turbines — runner imbalance and thrust bearing clearance measurement
This probe integrates directly with Bently Nevada 3300 XL and 3500 series monitoring racks, making it the preferred choice for plant engineers upgrading legacy Proximitor® systems or commissioning new machinery protection infrastructure.

Why Engineers Specify This Model
- API 670 Compliant — meets the machinery protection standard required by EPC contractors and end-users in oil & gas
- NSv Calibration — factory-calibrated for non-standard target materials, eliminating field calibration errors on exotic alloys
- 16 mm Tip — optimal sensing range for shaft diameters 50–300 mm, covering the majority of industrial rotating equipment
- 1 m Integral Cable — minimizes connector joints in high-vibration zones, reducing signal noise and failure points
- Direct 3300/3500 Rack Compatibility — plug-and-play with existing Bently Nevada monitoring infrastructure, no signal conditioning adapters required
- High-Temperature Rating — suitable for hot-section turbine bearing pedestals where ambient temperatures exceed 150°C

Application-Specific FAQ
Q: Is the 330908-00-16-10-02-05 compatible with the 3500 monitoring rack?
A: Yes. The 3300 NSv probe series is fully compatible with 3500 series Proximitor® drivers (330180 series) and monitor modules when used with the correct extension cable.
Q: What is the difference between NSv and standard 3300 probes?
A: NSv (Non-Standard voltage) probes are factory-calibrated for target materials other than AISI 4140 steel, such as Inconel, titanium, or duplex stainless. The scale factor is adjusted at the factory to maintain accuracy on these alloys.
Q: Can this probe be used in a hazardous area (Zone 1 / Division 1)?
A: The standard 330908 series is not ATEX-rated. For hazardous area installations, specify the 330905 (ATEX) or 330900 (FM) series. Contact us for guidance.
Q: What is the recommended gap setting for this probe?
A: The nominal installation gap is 1.0 mm (40 mil), placing the operating point at the center of the linear range. Verify with the Proximitor® output voltage: nominal -10.0 VDC at 1.0 mm gap.
Q: Do you offer calibration or repair services?
A: We partner with certified Bently Nevada service centers for calibration. Contact support@konmask.com for referrals and RMA coordination.
