The 31000-28-05-40-040-02-02 is an industrial-grade plastic probe housing assembly. It serves as a vital mechanical support and protective component for eddy current sensor systems. This assembly is typically applied to the exterior of bearing housings or casings of large rotating machinery.
Holds a Type 4X environmental protection certification
Certified with an IP66 rating for dust and water resistance
The housing is constructed from glass-fiber reinforced polyphenylene sulfide
The 31000/32000 Proximity Probe Housing Assemblies are recommended when mounting proximity probes through the machine case and are typically used for radially mounted transducers, whether vibration or Keyphasor measurements. Use of a Proximity probe housing allows external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without disassembly of the machine.
The 31000/32000 Proximity Probe Housing Assembly is made of polyphenylene sulfide (PPS), an advanced, high strength, thermoplastic with excellent corrosion resistance. Other elements of the housing assembly are made of corrosion-resistant stainless steel. The housing can be ordered with installed 3300 XL Proximity Probes and a variety of conduit fittings.
The 31000/32000 Proximity Probe Housing Assembly is fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings. When installed in conjunction with an approved transducer system and appropriate I.S. barriers, the 31000/32000 Proximity Probe Housing Assembly can be used in intrinsically safe hazardous area applications.

Petrochemical Processing
Houses vibration sensors on large agitators, mixers, and extruders to ensure continuous polymer production.
Hydropower Generation
Protects displacement sensors on massive hydro-turbine main shafts and thrust bearings against water mist.
Nuclear Power Plants
Safeguards vibration monitoring probes on main feedwater pumps and reactor coolant pumps outside containment.
Wind Energy
Encases proximity sensors on main shafts and main gearboxes of utility-scale wind turbines to track mechanical wear.
During installation, the face of the internal eddy current probe must remain perpendicular to the measured shaft surface to avoid cross-interference or measurement errors, and the system retaining nut must be tightened precisely to 29.4 N·m (260 in·lb) to secure the sealing and locking reliability of the housing under mechanical vibration.
The 31000-28-05-40-040-02-02 is built with an AISI 304 stainless steel probe sleeve, an AISI 303 stainless steel outer sleeve, and an AISI 304 stainless steel retaining chain. Neoprene O-rings are utilized at key interfaces to guarantee durable static and dynamic sealing.
How to use products like 31000-28-05-40-040-02-02?
Mount it onto a drilled and tapped hole on the bearing housing or machine case via its 3/4-14 NPT thread. Position the internal probe toward the shaft surface, adjust the probe gap using the external sleeve, lock it in place, and route the cable out through the conduit fittings.
Can 31000-28-05-40-040-02-02 be used in hazardous or explosive areas?
Yes. Its conductive plastic housing meets CENELEC EN50014 standards for electrostatic dissipation, and the integrated probe itself carries multiple international explosion-proof certifications.
