Secondly, the 21000-16-05-00-105-03-02 ensures stable probe positioning. Besides, it protects sensitive probes from dust, moisture, and mechanical impact. Thirdly, the assembly complies with API 670 standards for machinery protection systems. Meanwhile, CSA-approved versions support explosion-proof applications in hazardous areas.
Technical Insights
The housing assembly accepts 3300 XL 8mm proximity probes. Additionally, it includes a 0.5 m probe sleeve length. The aluminum body weighs approximately 1.1 kg without fittings. Furthermore, threaded ports accommodate 3/4-14 NPT conduit connections. The design also supports reverse-mount probe configurations. Meanwhile, the housing maintains CSA Type 4 enclosure certification. Therefore, it suits turbine, compressor, and pump monitoring applications.
Installation & Maintenance
Firstly, verify the mounting surface is clean and flat. Moreover, inspect all threaded ports for damage. Then, thread the housing into position using specified torque values. Besides, apply anti-seize compound to stainless steel threads. Next, insert the proximity probe gently into the housing. After that, set the nominal gap to 1.0 mm (40 mils) using a calibrated voltmeter. Finally, lock the probe with the jam nut. During maintenance, check seal integrity and cable condition. Furthermore, verify gap voltage stability during scheduled outages.
