Bently Nevada 31000-16-05-00-036-03-00 – Eddy Current Proximity Probe Housing Assembly | 3300 Series Platform
The Bently Nevada 31000-16-05-00-036-03-00 is a precision-engineered proximity probe housing assembly designed for the industry-standard 3300 Series continuous vibration monitoring platform. Engineered to protect and position eddy current probe tips with micron-level repeatability, this housing assembly is the mechanical backbone of reliable shaft displacement and vibration measurement in rotating machinery. Procurement engineers specify this exact part number when replacing worn housings, commissioning new monitoring loops, or upgrading legacy installations to maintain OEM-grade measurement integrity.
Product Positioning: This is a direct OEM-equivalent housing assembly — not an aftermarket substitute. The 31000-16-05-00-036-03-00 is sourced from verified Bently Nevada supply channels and is fully compatible with 3300 Series extension cables, proximitors, and monitoring rack cards. It is the preferred choice for facilities operating under API 670 machinery protection requirements.

- Petrochemical & Refining: Reactor agitator shaft monitoring; high-temperature process pump bearing clearance measurement.
- LNG & Offshore Platforms: Marine-grade corrosion resistance makes this housing suitable for humid, salt-laden environments where standard carbon steel housings fail prematurely.
- Pulp & Paper / Heavy Industry: High-speed roll and dryer section shaft monitoring where continuous uptime is critical.
- OEM Machine Builders: Integrated into new turbomachinery skids requiring pre-certified vibration monitoring loops.
Engineering Advantages
- OEM Dimensional Accuracy: Machined to Bently Nevada factory tolerances — ensures the probe tip sits at the correct gap distance without field shimming or recalibration.
- 316 SS Construction: Superior resistance to H₂S, chlorides, and process condensate compared to standard 304 SS or carbon steel alternatives.
- Integral Armored Cable: Factory-terminated coaxial cable eliminates field-splice failure points — a leading cause of false vibration trips.
- IP67 Sealing: Withstands wash-down, steam cleaning, and temporary immersion — critical for petrochemical and food-grade environments.
- Drop-in Replacement: Identical form, fit, and function to the original OEM part — no re-engineering of mounting brackets or cable routing required.
- API 670 Ready: Meets the mechanical protection standard for critical and essential machinery — accepted by insurance underwriters and plant safety auditors without additional documentation.
System Architecture & Signal Flow
The 31000-16-05-00-036-03-00 housing assembly is the first element in a three-component eddy current measurement chain:
- 1. Probe Housing Assembly (this part) → Positions the eddy current tip at the target shaft surface. The 316 SS housing threads into the bearing housing bracket and locks with a jam nut. The integral 0.9 m cable routes to the junction box.
- 2. Extension Cable → A 3300 XL Series extension cable (ordered separately by length) connects the probe to the proximitor module. Total system cable length must match the proximitor calibration range.
- 3. Proximitor / Oscillator-Demodulator → Converts the eddy current signal to a DC voltage proportional to gap distance. Output feeds the 3500 Series rack monitor or DCS analog input card.
Signal integrity depends on maintaining the correct total cable length (probe + extension). Mixing cable lengths from different calibration sets will shift the linear range and introduce measurement error — always verify the system calibration sheet before ordering.
Sourcing & Quality Verification
- Source: Procured through verified Bently Nevada / Baker Hughes authorized distribution channels.
- Inspection: Each unit undergoes incoming inspection including dimensional check, continuity test, and insulation resistance verification before shipment.
- Documentation: Certificate of Conformance (CoC) and test report available upon request — standard for API 670 installations requiring traceability.
- Shelf Life: Stored in climate-controlled warehouse; ESD-safe packaging for coaxial connector protection.
- Counterfeit Risk: Bently Nevada proximity probes are a known target for counterfeit parts. Konmask.com sources exclusively from traceable supply chains — we do not purchase from grey-market brokers.
Procurement Process
- Step 1 — Verify Part Number: Confirm 31000-16-05-00-036-03-00 against your system calibration sheet and existing probe housing label. Check cable length suffix matches your extension cable set.
- Step 2 — Request Quote: Contact support@konmask.com or call +0086 19859288691 with your required quantity and delivery timeline.
- Step 3 — Documentation: Specify if CoC, material traceability report, or third-party inspection is required at time of order — not after shipment.
- Step 4 — Shipping: Standard lead time: 3–7 business days ex-stock. Express DHL/FedEx available for shutdown-critical orders. Export documentation (HS Code 9031.80) prepared for international shipments.
- Step 5 — Installation Support: Konmask technical team can advise on gap setting procedure, system calibration verification, and proximitor compatibility — contact us before installation if uncertain.
Technical FAQ
Q: Is the 31000-16-05-00-036-03-00 compatible with the Bently Nevada 3500 Series monitoring rack?
A: Yes. The probe housing assembly is compatible with the 3500 Series rack when paired with the correct extension cable and proximitor. The 3500 rack accepts the standard 200 mV/mil output from this probe system.
Q: What is the difference between the 31000 and 32000 series housing assemblies?
A: The 31000 series uses a standard M10 thread mount; the 32000 series uses a larger M14 thread for higher-vibration or larger bearing housing applications. Verify your bracket thread before ordering.
Q: Can I use a longer extension cable to reach a remote junction box?
A: Only if the total system cable length (probe + extension) matches the proximitor calibration. Bently Nevada proximitors are calibrated for specific total lengths (e.g., 5 m, 9 m). Exceeding the calibrated length shifts the linear range. Contact us to confirm compatibility.
Q: Does this housing require recalibration after installation?
A: The housing itself does not require calibration — it is a passive mechanical component. However, the complete probe system (probe + extension + proximitor) should be gap-calibrated per Bently Nevada procedure TN-13 after installation or replacement.
Q: What is the lead time for urgent shutdown orders?
A: In-stock units ship within 24 hours via express courier. Contact support@konmask.com immediately for shutdown-critical requirements — we maintain emergency stock of common Bently Nevada probe assemblies.
