Description：

To externally mount proximity probes, use one of these all-metal Proximity Probe Housing Assemblies:

21000 aluminum probe housing assembly

24701 stainless steel probe housing assembly

The 21000, 24701, and 164818 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion prooffor hazardous areas.

You can order hazardous area approvedproximity probes with 21000 aluminum and24701 stainless steel housings for intrinsicallysafe applications. Both housings are certifiedas CSA Type 4 enclosures and are fullycompliant with the American PetroleumInstitute's (API) 670 Standard for externallymounted proximity probe housings.

Product Applications

Oil and Gas/Petrochemical Plants: Used for bearing vibration monitoring in refinery cracking compressors, liquefied natural gas (LNG) pumps, and high-power motors. Its robust explosion-proof certification ensures safe operation in flammable and explosive gas environments.

Coal and Hydropower Plants: Monitors axial displacement and radial vibration of core steam turbine generator units, gas turbines, and large feedwater pumps to prevent catastrophic shutdowns due to equipment imbalance or misalignment.

Large Metallurgical/Steel Plants: External protection for sensors in high-pollution, high-temperature, and high-vibration areas such as blast furnace blowers and rolling mill main drive systems.
