The 31000-00-00-15-047-01-02 is a Bently Nevada 31000 series Proximity Probe Housing Assembly designed for mounting proximity probes through machine cases, typically utilized in radial vibration or Keyphasor reference measurement applications.
API 670 Compliant
High Waterproof/Dustproof Rating
Multiple Agency Approvals
According to the standard configuration of this model code, 31000 specifies the base proximity probe housing assembly. The first -00 indicates no probe is included, and the second -00 indicates no probe connector option is selected. The -15 denotes the fitting option (typically defining specific conduit entry threads). The -047 specifies the precise sleeve length of 4.7 inches. The -01 designates the standoff adapter length option, and the trailing -02 indicates the Selection of Multiple Hazardous Area Agency Approvals.
The main housing structure is constructed from polyphenylene sulfide (PPS) thermoplastic, while the remaining assembly elements are made of stainless steel. The assembly provides external access to the internal probe cavity and extension cable, permitting gap adjustment or component replacement without machine disassembly. This configuration fully complies with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings and is certified for designated hazardous area installations.

Fossil Fuel Power Generation
Protecting externally mounted bearing vibration probes from high-temperature ambient air while providing a 4.7-inch penetration channel to reach the internal shaft target.
Petrochemical Refineries
Encasing proximity probes in an IP66 rated enclosure to isolate electrical connections from hazardous process gases and corrosive chemicals present in the atmosphere.
Oil and Gas
Allowing online adjustment and external replacement of speed or phase reference probes without shutting down the pipeline or dismantling the turbine casing.
Nuclear Power Facilities
Providing an API 670 compliant structural mounting barrier that isolates sensitive vibration sensors from harsh mechanical impacts and ambient environmental stresses.
Iron and Steel Mills
Shielding the internal proximity probe and its coaxial cable connectors from heavy iron dust particles and excessive ambient heat radiated by nearby blast furnaces.
When performing online adjustments, strictly follow safety protocols to prevent pressurized oil or gas leaks from the bearing housing. After tuning the 4.7-inch sleeve penetration depth, inspect the O-ring position and keep the internal coaxial cable free-moving without synchronous rotation or sharp bends to avoid core torsion failure. Tighten the 3/4-14 NPT mounting thread strictly to the 35 N·m specification. Secure the M25 cable fitting and lock unused conduit ports with the included metal plugs to maintain the NEMA 4X and IP66 environmental seals.
Model 31000-00-00-15-047-01-02 belongs to the Bently Nevada 31000 series proximity probe housing assemblies for machinery condition monitoring. This hardware is mounted directly onto the casing surface of large industrial rotating machinery, including high-pressure pumps, steam turbines, and large compressors, to provide external physical protection, environmental sealing, and an insertion depth adjustment channel for non-contacting proximity probes.
It is an externally mounted proximity probe housing assembly.
What metal is used for the internal probe sleeve of 31000-00-00-15-047-01-02?
