Bently Nevada 21000, 24701 and 164818 Probe Housing Assemblies provide mechanical mounting and protection for proximity probes installed through machinery casings. The 21000 uses an aluminum housing and the 24701 a stainless steel housing; both incorporate a stainless steel probe sleeve, removable dome cover, seals and threaded conduit ports. The 164818 provides a compact configuration for restricted spaces, with selectable cap height, sleeve length and connection threads. Probe options include 3300 XL 8 mm, 11 mm and NSv types, depending on the selected assembly. For the 21000 and 24701, adjustable probe penetration and optional standoff adapters accommodate different installation depths. These assemblies provide access to the probe and its cable during installation and maintenance, with dimensions selected around casing geometry and probe clearance.
