Bently Nevada 31000-28-05-00-059-02-02 – Proximity Probe Housing Assembly | 3300 XL Series Platform
Engineering Background: The Bently Nevada 31000 and 32000 Series Proximity Probe Housing Assemblies are purpose-engineered mechanical enclosures designed to mount, protect, and precisely position eddy-current proximity probes in rotating machinery monitoring systems. These assemblies are integral to the Bently Nevada 3300 XL continuous monitoring platform — the industry benchmark for turbomachinery protection in power generation, oil & gas, and petrochemical facilities.
Product Positioning: Part number 31000-28-05-00-059-02-02 is a field-proven housing assembly that ensures probe tip-to-target gap accuracy, mechanical rigidity under vibration, and environmental sealing in demanding industrial environments. It is fully compatible with Bently Nevada 3300 XL proximity transducer systems and integrates directly with existing cable and extension assemblies without modification.

- Reduced Downtime: Pre-assembled and factory-verified; ready for immediate installation during planned or emergency maintenance windows.
- Long Service Life: Corrosion-resistant materials rated for continuous operation in hydrocarbon, steam, and high-humidity environments.
System Architecture & Signal Flow
The 31000-28-05-00-059-02-02 housing assembly positions the eddy-current probe tip at the correct standoff distance from the rotating shaft or target. The probe generates a high-frequency electromagnetic field; shaft displacement modulates the field, producing a voltage signal proportional to gap distance. This signal passes through the extension cable to the Bently Nevada 3300 XL proximitor/driver, which conditions and transmits the measurement to the monitoring rack (e.g., 3500 Series) for real-time vibration, position, and eccentricity analysis.

Technical FAQ
Q: Is this assembly compatible with the Bently Nevada 3500 monitoring rack?
A: Yes. The 31000/32000 series probe and housing assemblies are designed to interface with 3300 XL proximitors, which feed signal to 3500 Series monitoring racks via standard Bently Nevada cabling.
Q: What is the correct installation gap for this probe housing?
A: The nominal gap is typically 1.0–1.5 mm (–10 to –15 VDC output), but always refer to the specific machine OEM documentation and Bently Nevada calibration procedures for your application.
Q: Can I use this housing with non-Bently Nevada probes?
A: Not recommended. The housing thread and tip geometry are optimized for Bently Nevada 31000/32000 series probes. Using third-party probes may compromise measurement accuracy and system certification.
Q: Do you offer expedited shipping for plant shutdowns?
A: Yes. Contact [email protected] or call +0086 19859288691 to arrange priority freight.
Q: Is a datasheet or dimensional drawing available?
A: Yes, available upon request for qualified procurement engineers. Contact our technical team with your project details.
