Industry Applications
Steam and Gas Turbine Monitoring
In power generation, the housing's IP66 and Type 4X ratings protect the probe from moisture and dust ingress, ensuring uninterrupted vibration data from turbine bearings. The 3/4-14 NPT mounting thread (Option 02) provides a secure, leak-proof installation in high-pressure steam environments.
Compressor and Pump Protection
For centrifugal compressors in oil and gas facilities, the housing's glass-reinforced PPS material withstands corrosive atmospheres and wide temperature swings (-51°C to +105°C). The included fittings (two plugs, one 3/4-14 NPT fitting, reducer, and cable seal grip) simplify field installation with various cable sizes.
Harsh Environment Reliability
The conductive fibers in the PPS material dissipate electrostatic charges, meeting CENELEC EN50014 requirements for hazardous areas.

Installation & Setup Guidance
Proper installation of the 31000-16-05-00-100-03-02 begins with verifying the mounting thread (3/4-14 NPT) matches the machine port. Apply the recommended torque of 29.4 N·m (260 in·lb) to the retaining nut to ensure a tight seal without damaging the housing. The cable seal grip accommodates cable diameters from 1/8 to 3/8 inches; select the appropriate grommet to maintain the IP66 rating. For hazardous area compliance, ensure the grounding liner is installed and the cover is fastened securely.
Maintenance & Reliability
Periodic inspection of the O-ring (Neoprene) and cable seal grommets is recommended to maintain environmental sealing. Check the retaining chain and sleeve (AISI 304 stainless steel) for corrosion or wear, especially in offshore or chemical processing environments. The housing's robust construction minimizes maintenance intervals, but verify the protective ratings (Type 4X, IP66) remain intact after any service activity.
Robust Protection for Critical Vibration Monitoring
Industrial rotating machinery demands reliable vibration monitoring to prevent catastrophic failures. The Bently Nevada 31000-16-05-00-100-03-02 proximity probe housing provides a rugged, environmentally sealed enclosure for the 3300 XL 8 mm probe, ensuring accurate measurements in the harshest conditions. This component is essential for protecting sensitive eddy-current probes in applications ranging from steam turbines to centrifugal compressors.

Selection Guide & Purchasing Advice
When selecting a replacement or new proximity probe housing, confirm the probe option (3300 XL 8 mm), cable length (0.5 m), and penetration depth (10 in) match your existing system. The 31000-16-05-00-100-03-02 is a complete assembly with all necessary fittings for quick deployment. For lifecycle status and availability, please verify with AutoDCSTech before ordering.
