Vibration Monitoring Solution – Bently Nevada 31000-30-05-15-049-03-02 | 3300 Series Proximity Probe Housing Assembly
Where This Product Is Used
The Bently Nevada 31000-30-05-15-049-03-02 Proximity Probe Housing Assembly is a precision eddy-current sensing component engineered for continuous, non-contact shaft vibration and position measurement in rotating machinery. It is deployed in the most demanding industrial environments where uptime is non-negotiable:
- Steam & Gas Turbines – Radial vibration and axial position monitoring on HP/LP turbine shafts in power generation plants.
- Centrifugal Compressors – Real-time shaft orbit tracking in petrochemical and LNG compression trains.
- Pumps & Fans – Continuous displacement monitoring in critical process pumps and induced-draft fans.
- Gearboxes – Gear mesh frequency analysis and shaft eccentricity detection.
- Marine Propulsion Systems – Shaft alignment verification and vibration surveillance on vessel drive trains.
- Nuclear & Fossil Power Plants – Safety-critical machinery protection per API 670 requirements.

Application-Specific FAQ
Q: Is the 31000-30-05-15-049-03-02 compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. When paired with the correct 3300 XL Proximitor driver and extension cable, this probe integrates directly with the 3500 series rack without additional signal conditioning.
Q: Can this probe be used in hazardous (Zone 1 / Zone 2) areas?
A: ATEX/IECEx-certified variants are available. Confirm the suffix code on your part number or contact us to verify the appropriate certification for your installation.
Q: What is the recommended gap voltage for initial setup?
A: Bently Nevada recommends a nominal gap voltage of –10 VDC (±0.5 V) for the 8 mm probe in a standard 3300 XL system. Refer to the system TDI for machine-specific settings.
Q: Do you supply calibration certificates?
A: Yes. A factory certificate of conformance is included with each unit. Third-party calibration reports can be arranged upon request.
Q: Can I order a single unit or do you require minimum quantities?
A: Single-unit orders are accepted. Volume pricing is available for orders of 5 units or more.
