24701-33-05-00-029-04-02 Bently Nevada Proximity Probe Housing Assemblies

Description:

To externally mount proximity probes, use one of these allmetal Proximity Probe Housing Assemblies:
    21000 aluminum probe housing assembly
    24701 stainless steel probe housing assembly
The 21000, 24701, and 164818 Proximity Probe Housing Assemblies consist of the following parts:
    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
    An optional standoff adapter

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.

The 164818 Compact Proximity Probe Housing is also available for applications with space restrictions. Ceramic capped probes are available with the 164818 housing.

Sleeve length is determined by the location in which the probe and housing are installed. The probe lead must be longer than the sleeve. Sleeve lengths longer than 304 mm (12 inches) require additional sleeve support to reduce the vibration associated with unsupported long sleeve lengths.

Bently Nevada offers a probe support and oil seal (part number 37948-01) for long sleeves that must go through an inner bearing housing. We also make custom sleeve supports.
