This system acts as a protective conduit and enclosure, enabling the installation of proximity probes directly through machinery casings while maintaining seal integrity and environmental shielding.\u003c\/p\u003e\n\n\u003cp\u003eThis specific configuration integrates a \u003cstrong\u003e3300 XL 8 mm\u003c\/strong\u003e proximity probe featuring multiple international hazardous area approvals. With an overall probe penetration depth of 7.3 inches, the assembly installs directly into machine housings via 3\/4-14 NPT threads. The external mechanical layout is constructed with a rugged aluminum body paired with a durable 304 stainless steel sleeve to deliver superior defense against corrosive and high-vibration operating conditions.\u003c\/p\u003e\n\n\u003cp\u003eNote: This component configuration has a direct transition path to updated equivalents, such as the 21000-16-05-00-073-04-02 housing assembly. It remains a key maintenance and replacement part for existing plant instrumentation layouts.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n
