Installation and Setup Guide

Mount the housing using the 3/4-14 NPT thread. Ensure the standoff adapter (1.5 in) is correctly positioned for probe penetration of 6.5 in. The assembly includes a dome cover, threaded ports for conduit connections, and O-rings. For explosion-proof installations, order the housing with E:00, E:01, E:02, or E:04 options. Always follow the manufacturer’s manual for torque specifications and wiring.

Maintenance and Reliability Tips

Regularly inspect the O-rings and thread seal for wear. Verify the probe cable integrity and connector protector condition. The aluminum body and stainless steel sleeve resist corrosion in harsh environments. Periodically check the mounting thread for tightness. For safety-rated equipment, follow the manufacturer’s safety manual for inspection intervals.

Compatibility and Integration

The 21000 housing assembly works with Bently Nevada proximity probes and monitoring systems. It is designed for reverse mount probes and accepts optional conduit fittings. The CSA Type 4 enclosure ensures dust and water ingress protection. For integration, consult the system’s compatibility documentation.
