Bently Nevada 31000-16-05-15-040-02-02 English Proximity Probe Housing Assemblies

Description

The 31000-16-05-15-040-02-02 is a robust English Proximity Probe Housing Assembly designed for machinery vibration and position monitoring, specifically configured for use with 3300 XL 8 mm probes. This assembly allows for secure, external mounting of proximity probes through the machine case, enabling gap adjustment or probe replacement without the need to disassemble the machinery. The housing is constructed from polyphenylene sulfide (PPS), a high-strength thermoplastic known for its excellent corrosion resistance, while metallic components are crafted from stainless steel for durability in harsh industrial environments. This specific configuration includes a 0.5 meter probe cable length (Option 05), a 15-unit standoff adapter length, and a 40 mm probe penetration depth (Option 040). The assembly provides environmental and mechanical protection for the transducer, ensuring long-term signal integrity for radial vibration measurements. It is compliant with API 670 standards for externally mounted proximity probe housings and is compatible with various conduit fittings (Option 02: two M25 fittings, one plug) and mounting threads (Option 02: 3/4-14 NPT).

Installation Guidelines

Ensure the outer sleeve is correctly installed into the machine case before fitting the housing. Adjust the probe gap through the probe sleeve. When utilizing M25 fittings, ensure conduit connections are sealed properly to maintain environmental protection ratings. The 31000 housing provides environmental and mechanical protection only and is not an explosion-proof assembly; for hazardous area applications, ensure it is installed with appropriate intrinsically safe barriers and approved transducer systems.

Compliance and Certifications

Complies with American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings. Suitable for intrinsically safe hazardous area applications when installed with approved transducers and I.S. barriers.
