Features:

  • Through-case mounting design with 3.7-inch probe penetration allows external gap adjustment and probe replacement without machine disassembly.
  • PPS thermoplastic housing with stainless steel components provides excellent corrosion resistance for long-term durability in harsh industrial environments.
  • Versatile cable entry options include a seal grip with three grommet sizes, a 3/4-14 NPT fitting, a stainless steel reducer, and two plugs for flexible field wiring.
The 31000-28-05-00-037-03-02 is specifically designed for applications where the probe must be mounted through the machine casing—a common requirement for radial vibration and Keyphasor measurements on large rotating equipment. Its through-case design provides external access to the probe and extension cable, allowing technicians to adjust probe gap or replace the probe entirely without disassembling the machine.

The 31000-28-05-00-037-03-02 is constructed from materials chosen for long-term reliability in harsh industrial conditions. The main housing is molded from polyphenylene sulfide (PPS), an advanced thermoplastic with excellent resistance to chemicals, moisture, and temperature extremes.

The 31000-28-05-00-037-03-02 is equipped with a comprehensive set of fittings to accommodate a variety of field installation scenarios. The included cable seal grip comes with three grommet sizes, covering the most common cable diameters encountered in industrial wiring.

The 31000-28-05-00-037-03-02 Bently Nevada English Proximity Probe Housing Assemblies may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Radial Vibration Monitoring: Mounted on a fluid thin-film bearing housing, it measures the dynamic vibration of the shaft.
  • Keyphasor: Monitors the keyways on the shaft, providing speed and phase signals.
  • Typical Equipment: Key industrial equipment such as steam turbines, compressors, pumps, motors, and generators.
  • Industry Standards: Fully compliant with API 670 standards for externally mounted probe enclosures.
  • Protection Rating: The enclosure is NEMA 4X and IP66 certified, providing protection against hose jets and corrosive environments.
  • Hazardous Area Certification: The built-in probe has multi-national explosion-proof certifications (defined by code 28), and the enclosure material is CENELEC EN50014 electrostatic dissipation certified, suitable for hazardous areas.
  • Probe Compatibility: This model comes pre-installed with a 3300 XL 8 mm probe, replacing or upgrading older 7200 series probe systems.
  • System Integration: Requires the 3300 XL Proximitor sensor. Since the probe cable is 0.5 meters, a 4.5-meter or 8.5-meter extension cable is typically required to form a standard 5-meter or 9-meter system.
  • Shell Material: Constructed from glass fiber reinforced polyphenylene sulfide (PPS) and stainless steel, offering excellent chemical resistance.
Description
The 31000-28-05-00-037-03-02 is built for through-case mounting of proximity probes, allowing external access for gap adjustment and probe replacement without machine disassembly. Its 3.7-inch probe penetration provides ample reach through machine casings for radially mounted transducers used in vibration and Keyphasor measurements.

This assembly is designed to accept 3300 XL 8 mm probes with multiple approvals, making it suitable for a wide range of industrial applications. The included cable seal grip accommodates three cable size ranges (1/8 to 3/16 in, 1/4 to 5/16 in, 5/16 to 3/8 in), providing flexibility for field wiring without requiring additional adapters. 

The 31000-28-05-00-037-03-02 includes a 3/4-14 NPT fitting and a stainless steel reducer to 1/2-14 NPT, allowing compatibility with a variety of conduit systems. The two plugs provide sealing options for unused ports, ensuring the housing maintains its environmental protection when not fully populated. 

With its combination of corrosion-resistant materials, flexible cable entry options, and through-case mounting capability, the 31000-28-05-00-037-03-02 is particularly well-suited for radial vibration and Keyphasor measurements on steam turbines, compressors, and generators.
