Industry Applications for the 31000 Probe Housing
The Type 4X and IP66 ratings ensure protection against hose-directed water and corrosive environments, making it suitable for outdoor and washdown areas. The glass-reinforced PPS housing with conductive fibers meets CENELEC EN50014 for electrostatic dissipation in hazardous locations.

Installation and Setup Guidance
When installing the 31000-28-05-70-066-00-02, ensure the mounting thread (3/4-14 NPT) is properly engaged. The recommended torque for the retaining nut is 29.4 N·m (260 in·lb). The housing is not designed to resist internal or external pressure, and probes are not pressure tested prior to shipment. Verify the probe cable length (0.5 in) and standoff adapter (7.0 in) match your application requirements.
Maintenance and Reliability
The stainless steel sleeve and retaining chain (AISI 304) and outer sleeve (AISI 303) provide corrosion resistance. The Neoprene O-ring between sleeve and housing should be inspected periodically for wear. The housing impact strength is certified by BASEEFA to withstand 4 Joule impacts at extreme temperatures (-39°C and +115°C) and 7 Joule at room temperature (CSA verified).
Robust Protection for Critical Vibration Monitoring
The Bently Nevada 31000-28-05-70-066-00-02 is a proximity probe housing assembly designed to seal differential pressure between the probe tip and housing main body when used with a 3300 XL 8 mm probe. This configuration includes a 0.5-inch probe cable length, a 7.0-inch standoff adapter, and 6.6-inch probe penetration. The mounting thread is 3/4-14 NPT. It is built for demanding industrial environments where reliable vibration monitoring is essential.

Compatibility and Integration
This housing is designed specifically for use with the 3300 XL 8 mm probe. The Viton O-ring inside the probe case ensures a reliable seal. For applications requiring pressure seal testing, contact Bently Nevada's custom design department.
Selection Guide and Purchasing Advice
When ordering the 31000-28-05-70-066-00-02, confirm the probe option, cable length, standoff adapter, and penetration length match your machinery train requirements. AutoDCSTech stocks this Bently Nevada housing assembly. Please verify current lifecycle status and availability before ordering.
