Description：

The Bently Nevada 21000-34-05-00-015-04-02 is an aluminum Proximity Probe Housing Assembly used to mount and protect externally installed proximity probes in machinery vibration and shaft position monitoring systems. It provides a stable installation point for the probe while allowing maintenance personnel to perform probe adjustment or replacement without dismantling the machine casing.

The 21000 Series is available with CSA explosion-proof certification for hazardous industrial locations. When combined with approved Bently Nevada proximity probes, the housing can be used in intrinsically safe installations where equipment must comply with hazardous-area regulations.

The required sleeve length depends on the installation depth between the machine casing and the monitoring point. The probe lead must always be longer than the sleeve to allow proper installation and cable routing. For sleeve lengths exceeding 304 mm (12 inches), additional mechanical support is recommended to minimize vibration of unsupported sleeve sections and maintain probe stability during operation.
