Bently Nevada 31000-28-05-00-037-03-02 Proximity Probe Housing

Technical Specifications Breakdown

Key parameters for the 31000-28-05-00-037-03-02 are listed below for quick reference:

Real-World Applications in Harsh Environments

Typical installations include steam turbine bearing housings, compressor casings, and pump stations in oil refineries or chemical plants. The Type 4X and IP66 ratings ensure the assembly resists hose-directed water and corrosive atmospheres, while the glass-reinforced PPS with conductive fibers provides electrostatic dissipation in hazardous areas.

Installation and Setup Guidance

When installing, ensure the 3/4-14 NPT mounting thread is properly engaged. The assembly 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. Use the recommended retaining nut torque of 29.4 N·m (260 in·lb) to maintain the seal. The housing is not designed to resist internal or external pressure; contact the custom design department if pressure testing is required.

Maintenance and Reliability

Periodically inspect the Neoprene O-ring between the sleeve and housing for signs of wear or compression set. Verify the Viton O-ring inside the probe case remains intact. The AISI 304 stainless steel sleeve and retaining chain, plus AISI 303 outer sleeve and screws, offer corrosion resistance. The housing has been certified by BASEEFA to withstand two separate 4 Joule impacts at -39°C and at 115°C, and CSA verified a 7 Joule impact at room temperature.

Robust Protection for Critical Vibration Monitoring

For maintenance engineers overseeing rotating machinery, the Bently Nevada 31000-28-05-00-037-03-02 proximity probe housing delivers a rugged, sealed enclosure designed to withstand harsh industrial environments. This housing assembly is purpose-built for use with 3300 XL 8 mm probes, providing reliable differential pressure sealing between the probe tip and the main body.

Selection Guide and Purchasing Advice

For maintenance teams standardizing on Bently Nevada 3300 XL 8 mm probes, this housing provides a complete solution with a 0.5 m cable and 3.7 in probe penetration. The standoff adapter option is not included (00), so order separately if needed. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
