Turbine & Rotating Machinery Vibration Monitoring Solution – Bently Nevada 330905-00-05-05-02-05 | NSv Series
Where This Product Is Used
The Bently Nevada 330905-00-05-05-02-05 NSv Proximity Probe is an eddy-current, non-contact displacement sensor engineered for continuous shaft vibration, axial position, and differential expansion measurement in critical rotating machinery. Typical deployment environments include:
- Steam & Gas Turbines – radial shaft vibration and thrust position monitoring per API 670
- Centrifugal Compressors – real-time rotor orbit and clearance measurement
- Pumps & Fans – bearing journal displacement in petrochemical and power-generation trains
- Gearboxes – gear mesh frequency and shaft eccentricity detection
- Hydro Turbines – guide-vane and runner shaft position feedback
- Marine Propulsion Systems – propeller shaft radial and axial displacement

Application-Specific FAQ
Q: Is the 330905-00-05-05-02-05 compatible with the Bently Nevada 3500 rack?
A: Yes. The NSv probe is designed to interface directly with the 3500 Series Proximitor® monitors (3500/40M, 3500/42M) using the matched extension cable and driver.
Q: What is the standard gap voltage and linear range?
A: Typically –10 VDC at 2.0 mm (80 mil) gap with a linear range of approximately 0.25 mm to 2.54 mm (10–100 mil). Refer to the factory calibration sheet supplied with each unit for exact values.
Q: Can this probe be used on non-ferrous target materials?
A: The probe is factory-calibrated for AISI 4140 steel. Bently Nevada provides target material correction factors for aluminium, titanium, and other alloys — contact us for the applicable correction table.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock situations, typical lead time is 4–8 weeks from the factory. Contact us for current availability.
Q: Do you provide a warranty?
A: Yes. All units carry a 12-month warranty against manufacturing defects. Warranty claims are processed through Konmask.com with full RMA support.
