Bently Nevada 31000-16-05-35-026-03-02 English Proximity Probe Housing Assemblies

Description

The 31000-16-05-35-026-03-02 is a Bently Nevada proximity probe housing assembly, configured specifically for the 3300 XL 8 mm proximity probe system. This assembly is designed to provide mechanical and environmental protection for proximity probes mounted through machine cases, facilitating radial vibration and position measurements. Constructed from polyphenylene sulfide (PPS), this housing offers superior corrosion resistance while allowing external access to the transducer for gap adjustments or probe replacements without requiring machine disassembly.

This specific configuration includes a 3.5-inch standoff adapter and a 2.6-inch probe penetration depth, utilizing a 3/4-14 NPT mounting thread. It is supplied with an M20 conduit fitting and two plugs, ensuring compatibility with standard industrial cable and conduit systems. This housing assembly adheres to API 670 standards for externally mounted proximity probe housings.

Installation Guidelines

Ensure that the machine casing is properly affixed to the bearing to maintain an accurate relative vibration signal. Install the outer sleeve into the machine case, then insert the probe sleeve to adjust the probe gap. The housing design permits full external access, allowing the user to reconnect probe cables and tighten housing cover captive screws after installation. Always verify thread engagement and seal unused holes with the provided plugs to maintain environmental integrity.

Compliance and Certifications

The 31000 series housing assemblies are compliant with the American Petroleum Institute (API) 670 Standard. When installed with an approved Bently Nevada transducer system and appropriate safety barriers, the assembly is suitable for use in intrinsically safe hazardous area applications.
