Steam Turbine and Compressor Monitoring
In power generation and petrochemical facilities, steam turbines and centrifugal compressors require continuous vibration monitoring. The 31000-16-05-00-068-03-02 housing protects the 3300 XL 8 mm probe from moisture, dust, and physical impact, ensuring uninterrupted data collection. Its wide temperature range (-51°C to +105°C) accommodates both cold startup and hot operating conditions.
Hazardous Area Installations
With CENELEC EN50014 certification for electrostatic dissipation of plastic material in hazardous areas, this housing is suitable for environments where flammable gases or dusts may be present. The conductive fiber-filled PPS material prevents static charge buildup, reducing ignition risk.
Outdoor and Washdown Environments
The Type 4X and IP66 ratings mean the housing resists hose-directed water and corrosion.

Installation and Setup Guidance
When installing the 31000-16-05-00-068-03-02, ensure the mounting thread (3/4-14 NPT) is properly engaged with the mating port. The fittings option includes a 3/4-14 NPT plug, a reducer to 1/2-14 NPT, and a cable seal grip with grommets for cable diameters from 1/8 to 3/8 inches. Use the provided grommet that matches your cable size to maintain the IP66 seal. Tighten the retaining nut to the recommended torque of 29.4 N·m (260 in·lb) to ensure a secure, leak-free joint.
Maintenance and Reliability
Periodically inspect the Neoprene O-rings and cable seal grommets for signs of wear or cracking, especially after exposure to extreme temperatures or chemicals. The stainless steel outer sleeve and retaining chain resist corrosion, but verify that all exterior screws remain tight. The housing is not designed to withstand internal or external pressure; if your application requires pressure testing, contact the custom design department.
Robust Protection for Critical Vibration Monitoring
When machine health depends on accurate proximity probe measurements, the enclosure protecting that probe must withstand extreme conditions. The Bently Nevada 31000-16-05-00-068-03-02 provides a sealed, impact-resistant housing for 3300 XL 8 mm probes, ensuring reliable operation in the harshest industrial environments.

Selection Guide and Purchasing Advice
When selecting a replacement or new proximity probe housing, verify that the probe option (16 = 3300 XL 8 mm) and penetration depth (068 = 6.8 in) match your existing probe assembly.
