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, O-rings, a reverse mount proximity probe, a thread seal, optional conduit fittings, and an optional standoff adapter.

The use of a proximity probe housing allows external access to the proximity probe and its extension cable, making it easier to adjust the gap or replace the probe without needing to disassemble the machine.

The sleeve length is determined by the location where the probe and housing will be installed. The probe lead must be longer than the sleeve. If the sleeve length exceeds 304 mm (12 inches), additional sleeve support is required to reduce vibrations from unsupported long sleeves. A probe support/oil seal (P/N 37948-01) is available for long sleeves passing through an inner bearing housing, or a custom sleeve support can be provided by Bently Nevada or the customer.
