This assembly facilitates the external mounting of proximity probes (such as 3300 or 3300 XL 8mm transducers) through machine casings, allowing for external adjustment, servicing, and replacement without requiring access to the internal machinery wet areas. The \u003cstrong\u003e21000 Series\u003c\/strong\u003e housing is built to withstand high-vibration environments, oil-rich atmospheres, and extreme temperatures typical of heavy industrial installations.\u003c\/p\u003e\n\n\u003cp\u003eThe configurator code \u003cstrong\u003e21000-34-05-00-030-03-022\u003c\/strong\u003e defines the exact combination of probe cable fittings, conduit threads, mounting threads, sleeve lengths, and reverse-mount probe options required to interface with the target machine casing.
