The 24701-16-05-033-04-02 is a 24701 series proximity probe housing assembly manufactured by Bently Nevada. This assembly is primarily used for mounting eddy current probes externally on rotating machinery, providing physical protection and allowing for external clearance adjustment without shutting down the machine.
O-rings
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.
