The 24701-28-05-00-038-04-02 Proximity Probe Housing Assembly operates to shield sensors in harsh machinery environments. This configuration specifies a 3.8-inch probe penetration depth and is supplied as a housing assembly without a pre-installed sensor, consisting of a dome cover that screws into the body of the housing, a probe sleeve, and conduit fittings.
Essential conduit fittings
A probe sleeve of optional length
A dome cover that screws securely into the housing body
The 24701-28-05-00-038-04-02 complies with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings and features a CSA Type 4 rating for environmental protection against moisture and dust. The externally mounted configuration enables proximity probe and extension cable access, allowing gap adjustment or probe replacement without machine disassembly.

Oil & Gas
Installed on long-distance pipeline compressor stations and offshore crude transport pumps to protect probes measuring shaft radial vibration, preventing early bearing and seal failures.
Petrochemical and Refining Industry
Utilized on hydrocracking compressors and catalytic cracking fans in refineries to monitor axial thrust displacement in hazardous locations, preventing rotor-to-stator friction.
Thermal Power Generation
Applied to steam turbines, main generators, and boiler feed pumps to protect sensors under high-temperature steam environments while tracking shaft radial runout and eccentricity.
Nuclear Power Generation
Deployed on main steam turbine generators within the conventional island of nuclear plants to provide continuous protection, securing high-reliability data for safety interlocks.
Hydroelectric Power Generation
Configured on hydro-turbine generators to shield against high humidity while measuring shaft runout and axial displacement caused by hydraulic unbalance.
Wind Power Generation
Installed in megawatt wind turbine gearboxes and main bearings, leveraging its CSA Type 4 rating to block humidity and salt spray while tracking axial play.
When installing the 24701-28-05-00-038-04-02 housing, seal all threaded connections with Teflon tape or sealant to maintain the CSA Type 4 and hazardous area explosion-proof ratings. This configuration excludes a pre-installed probe; a reverse mount probe must be selected independently and adjusted to the 3.8-inch penetration depth. Calibrate the initial probe gap via voltage measurement before tightening the dome cover, and utilize flexible explosion-proof conduits at the connections to block oil or dust ingress.
The 24701-28-05-00-038-04-02 is constructed with corrosion-resistant materials and enables external probe replacement and gap adjustment without machine disassembly, while maintaining required explosion-proof and environmental ratings.
It is a Bently Nevada proximity probe housing assembly.
