As a core external mounting component within Bently Nevada machinery protection architectures, this housing features a threaded dome cover that screws into the aluminum housing body, threaded ports for conduit connections, O-rings, and a thread seal to safeguard internal transducer assemblies.\u003c\/p\u003e\n\u003cp\u003eThis specific configuration \u003cstrong\u003e21000-00-00-00-000-00-02\u003c\/strong\u003e is supplied without an internal probe pre-installed (Probe Option 00) and without a probe cable (Cable Option 00), allowing customized field integration of compatible Bently Nevada reverse mount proximity probes. It is built without a standoff adapter (Standoff Adapter Option 00) and features a standard minimum probe penetration configuration (Penetration Option 000). The assembly is supplied without conduit fittings (Fittings Option 00) and incorporates a 3\/4-14 NPT mounting thread (Mounting Thread Option 02) with 5 to 7 full machined threads to ensure high structural mounting strength and stiffness on machine casings. Fully compliant with API 670 standards for externally mounted proximity probe housings, it provides robust environmental protection and mechanical support in industrial machinery protection and condition monitoring applications.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-Metal Aluminum Body Structure\u003c\/strong\u003e:
