  • PPS (Polyphenylene Sulfide) Housing Construction
  • API 670 Standard Compliance
  • Intrinsically Safe Hazardous Area Capability
  • NEMA 4X and IP66 Environmental Protection
The 31000-26-05-00-040-01-02 is a proximity probe housing assembly from the Bently Nevada 31000 series, manufactured by Bently Nevada (Baker Hughes). It is configured in English units with a 3300 XL 8 mm probe with connector and multiple hazardous area approvals, 0.5 meter probe cable, no standoff adapter, 4.0 inch probe penetration, one 1/2-14 NPT plug, and 1/2-14 NPT mounting thread.

The assembly consists of an aluminum housing body with a 304 stainless steel probe sleeve. The 4.0 inch probe penetration positions the probe tip at the required distance from the target surface, with no standoff adapter providing direct mounting to the machine case. The total sleeve extension from the mounting surface is 4.0 inches (101.6 mm), which is within the self-supporting range and does not require additional sleeve support.

The housing includes a dome cover that screws into the housing body, threaded ports for conduit connections, O-ring seals, a thread seal, and a single 1/2-14 NPT plug fitting. The 1/2-14 NPT mounting thread is machined with approximately 5–7 full threads to increase mounting strength and mechanical stability.

The 31000-26-05-00-040-01-02 Bently Nevada Proximity Probe Housing Assembly (English Version) may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.
The housing is rated as a CSA Type 4 enclosure, providing protection against dust and water ingress. It complies with the American Petroleum Institute (API) 670 Standard for externally mounted proximity probe housings.
The adjustment range for probe penetration is ±13 mm (±0.5 in), allowing field adjustment of the probe-to-target gap without disassembling the machine. The assembly allows external access to the proximity probe and its extension cable, enabling gap adjustment or probe replacement without disassembling the machine.

Mount the Outer Sleeve: Thread the outer sleeve of the housing assembly into the machine's 3/4-14 NPT tapped casing hole. Tighten it to the specified mechanical torque to prevent process leaks.
Insert the Probe Sleeve: Slide the probe sleeve through the outer sleeve.Set the Insertion Depth & Gap: Adjust the probe until it achieves the correct physical distance (gap) from the target surface (typically the rotating shaft).
Lock the Position: Slide the mechanical retainer under the retaining nut and tighten the nut securely to lock the probe's position in place.

Technical notes

The 31000-26-05-00-040-01-02 is designed to seal differential pressure between the probe tip and the housing main body when used with a 3300XL 8mm probe. The sealing material internal to the probe case consists of a Viton O-ring, while the O-ring between the sleeve and the housing is a Neoprene O-ring. The 31000 allows external access to the proximity probe and its extension cable, permitting gap adjustment or probe replacement without disassembly of the machine, which significantly reduces maintenance downtime and improves operational efficiency.
