The 21000 and 24701 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.
