Turbomachinery Vibration Monitoring Solution – Bently Nevada 31000-27-05-15-040-03-02 | 3300 Series
Where This Product Is Used
The Bently Nevada 31000-27-05-15-040-03-02 Proximity Probe Housing Assembly is engineered for continuous, non-contact shaft vibration and position measurement in rotating machinery. Typical deployment environments include:
- Steam and gas turbines in power generation plants
- Centrifugal and axial compressors in oil & gas processing
- Boiler feed pumps and large industrial pumps
- Gearboxes and expanders in petrochemical facilities
- Marine propulsion shafting systems
- High-speed spindles in precision manufacturing
This housing assembly secures and aligns the proximity probe tip at the precise radial or axial gap required by API 670 machinery protection standards, ensuring measurement integrity under high-temperature, high-vibration plant conditions.

Why Engineers Specify This Model
- Drop-in OEM replacement – exact dimensional match to original Bently Nevada 3300 Series installations; no re-machining of bearing housings required.
- API 670 compliant geometry – housing maintains the critical probe-to-shaft gap tolerance (±0.025 mm) demanded by machinery protection standards.
- Corrosion-resistant construction – stainless steel body withstands lube-oil, process gas, and steam environments.
- Plug-and-play with 3300 XL monitors – direct compatibility with Bently Nevada 3300/16 and 3500 series monitoring racks without signal conditioning changes.
- Reduced downtime risk – pre-assembled and factory-tested; ready for installation without field calibration of the housing itself.

Application-Specific FAQ
Q: Is the 31000-27-05-15-040-03-02 compatible with the Bently Nevada 3500 monitoring system?
A: Yes. The 3300 Series probe and housing assemblies are fully compatible with the 3500 rack when used with the appropriate Proximitor sensor. Verify the gap voltage range matches your monitor card input specification.
Q: Can this housing be used for axial position measurement as well as radial vibration?
A: The housing configuration (radial vs. axial) is determined by the suffix digits in the part number. The -03-02 suffix in this model indicates a specific orientation — confirm against your OEM installation drawing before ordering for axial duty.
Q: What is the recommended probe gap for this assembly?
A: Standard Bently Nevada 8 mm probes are gapped to approximately 1.0 mm (–10 VDC output at mid-range). Always verify against the specific Proximitor sensor calibration sheet supplied with your system.
Q: Do you provide a Certificate of Conformance?
A: Yes. A CoC is available upon request for all orders. Traceability documentation can be provided for critical service applications.
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 2–6 weeks depending on source availability. Contact us for real-time stock status.
