Bently Nevada offers two all-metal Proximity Probe Housing Assemblies for external mounting of proximity probes: the 21000 aluminum probe housing assembly, and the 24701 stainless steel probe housing assembly. These housings consist of a dome cover that screws into the body of the housing, threaded ports for conduit connections, a probe sleeve of optional length, 0- rings, a reverse mount proximity probe, a thread seal, optional conduit fittings and an optional standoff adapter. Use of a proximity probe housing allows external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without disassembly of the machine.
