Industry Applications for the 31000 Housing
The Type 4X and IP66 ratings ensure reliable operation in wet or dusty environments, while the wide temperature range supports outdoor installations in extreme climates. The housing is certified to withstand hose-directed water, making it suitable for washdown areas in food processing or chemical plants.

Installation and Setup Guidance
When installing the 31000-16-05-35-026-03-02, ensure the mounting thread (3/4-14 NPT) is properly engaged. The retaining nut should be torqued to 29.4 N·m (260 in·lb). The fittings option includes two plugs, one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT SST reducer, and a cable seal grip with grommets for cable sizes from 1/8 to 3/8 inches. Verify that the O-ring between the sleeve and housing is properly seated to maintain the seal.
Maintenance and Reliability
The housing is designed for long-term reliability with corrosion-resistant stainless steel components. The glass-reinforced PPS housing provides high impact strength, certified to withstand 4 Joule impacts at extreme temperatures. Periodic inspection of the O-ring and cable seal is recommended to preserve the IP66 rating. The housing is not designed to resist internal or external pressure; contact the custom design department if pressure testing is required.
Robust Protection for Critical Vibration Monitoring
When machinery uptime depends on accurate vibration data, the enclosure protecting your proximity probe must withstand harsh conditions. The Bently Nevada 31000-16-05-35-026-03-02 is a 31000 Proximity Probe Housing engineered for reliability in demanding industrial environments. This housing assembly is designed to seal differential pressure between the probe tip and the housing main body when used with a 3300 XL 8 mm probe, ensuring consistent measurement integrity.

Selection Guide and Purchasing Advice
When selecting a proximity probe housing, consider the probe type, cable length, standoff adapter, and penetration depth. The 31000-16-05-35-026-03-02 is configured for a 3300 XL 8 mm probe with a 0.5 m cable, 3.5 in standoff, and 2.6 in penetration. This combination is well-suited for standard vibration monitoring applications. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
