• A reverse mount proximity probe
• A probe sleeve of optional length
• A dome cover that screws into the body of the housing

The 21000, 24701, and 164818 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas. You can order hazardous area approved proximity probes with 21000 aluminum and 24701 stainless steel housings for intrinsically safe applications. Both housings are certified as CSA Type 4 enclosures and are fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.

Bently Nevada 21000-00-00-00-019-03-02 features conduit outlet fittings that include one 3/4-14 NPT metal plug, one reducer fitting, and one cable seal grip, utilizing a 3/4-14 NPT base mounting thread. This component serves as an external rigid protective enclosure for the rotating machinery condition monitoring sensor and is fixed to the bearing housing or machine casing wall. The internal hollow cavity and stainless steel sleeve are used for the subsequent installation of a separately purchased reverse-mount 8 mm proximity probe. This configuration allows for the matching of compatible 3300 or 3300 XL series sensors based on the actual static gap and measuring range of the rotating shaft at the site. Following a rigid connection through the 3/4-14 NPT base thread, external mechanical stress is isolated from the probe inside the housing.
