Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330907-05-30-70-02-00 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330907-05-30-70-02-00 is a 3300 NSv Reverse Mount Proximity Probe engineered for continuous, non-contact vibration and position measurement on high-speed rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – shaft radial vibration and differential expansion monitoring per API 670
- Centrifugal Compressors – rotor dynamic instability detection in petrochemical and LNG plants
- Pumps & Fans – bearing condition monitoring in power generation and water treatment facilities
- Gearboxes – gear mesh frequency analysis in heavy industrial drives
- Marine Propulsion Systems – shaft alignment and vibration surveillance on vessel drive trains
- Paper & Steel Mills – roll and spindle monitoring in continuous process lines
The reverse-mount configuration allows installation from the back of the bearing housing, making it ideal for retrofits and space-constrained machinery where front-access probes cannot be accommodated.

Why Engineers Specify This Model
- Reverse-Mount Geometry – Eliminates front-access machining; probe threads in from the non-drive end, preserving bearing housing integrity.
- NSv Technology – Superior signal-to-noise ratio vs. 3300 XL probes; reduces false trips in high-EMI environments.
- 5 mm Tip for Tight Clearances – Fits compact bearing housings where 8 mm probes cannot.
- Direct 3500 System Compatibility – Plug-and-play with Bently Nevada 3500 Series monitors; no re-ranging required.
- Wide Temperature Range – Rated to 177°C at probe tip for hot-section turbine applications.
- Long-Term Stability – Thermally compensated coil maintains calibration over multi-year continuous operation.

Application-Specific FAQ
Q: Compatible with older Bently Nevada 3300 XL monitors?
A: Yes. The 3300 NSv uses the same –24 VDC supply and 200 mV/mil sensitivity as the 3300 XL, making it backward-compatible with most 3300 XL monitor cards. Verify input impedance before installation.
Q: What target material is required?
A: Factory-calibrated for AISI 4140 steel. For stainless steel, titanium, or other alloys, a field re-calibration or material correction factor must be applied.
Q: Suitable for hazardous (Ex) areas?
A: ATEX/IECEx-rated variants are available. Confirm zone classification and gas group with your safety engineer before specifying.
Q: Maximum shaft speed?
A: Flat frequency response to 10,000 Hz (–3 dB). Practical limits are governed by the monitor card’s input bandwidth.
Q: Can Konmask supply the complete measurement loop?
A: Yes. Konmask.com stocks or can source all 3300 NSv and 3500 Series components. Contact us with your system architecture for a complete BOM quotation.
