Bently Nevada 31000-28-10-00-165-02-02 Probe Housing
The 16.5-inch approved 8 mm housing execution with two conduit fittings and one plugged port.
Key Information
31000-28-10-00-165-02-02 combines a multiple-approval 3300 XL 8 mm probe, 1.0 m lead, no standoff and 16.5-inch penetration in a Bently Nevada 31000 housing. Its E02 package supplies two 3/4-14 NPT fittings and one plug, while the F02 code provides the 3/4-14 NPT machine mounting thread.
This part differs from 31000-28-10-00-165-01-02 only in the fitting package, but that difference changes the conduit arrangement and available ports. The long sleeve still requires support near the probe.
Functions
- Provides two hardline-conduit connections for a long through-case probe installation.
- Protects and positions a multiple-approval 8 mm probe.
- Allows external adjustment without placing the electronics at the machine target.
- Maintains environmental sealing through the PPS housing, cover, O-rings and fittings.
- Supports an intrinsically safe measurement chain when installed with approved associated apparatus.

| Pressure Boundary | Not designed for internal or external pressure |
Installation
- Use both conduit fittings only where the wiring architecture genuinely needs separate routes or pass-through access.
- Provide rigid support close to the probe and confirm that it cannot contact rotating or moving components.
- Verify plug, fitting and cover seals after conduit loads are applied.
- Coordinate the probe approval with the barrier, field cable and monitor input documentation.
- Record final gap, support condition and conduit loading during commissioning.
Lifecycle
- Compare both conduit routes for moisture paths and mechanical loading during inspection.
- Check the sleeve support before changing probe position because the long assembly can be sensitive to support movement.
- Keep the pressure-containment plan separate from the environmental enclosure rating.
- Retain the exact E02 suffix so a single-fitting E01 housing is not supplied by mistake.
FAQ
When is 31000-28-10-00-165-02-02 preferable to the E01 version?
Choose the E02 build when two hardline-conduit connections are required by the field wiring plan; do not substitute it merely because both housings share the same penetration.
What clearance should be checked for 31000-28-10-00-165-02-02?
Confirm internal probe-tip clearance, sleeve-support space, external cover removal and bend room for both conduit entries.
How should sleeve-support movement be ruled out on 31000-28-10-00-165-02-02?
Inspect mechanical fastening, compare static gap before and after conduit loading, and review slow-roll data for a resonance or offset introduced by the support.
Can 31000-28-10-00-165-02-02 contain a process leak?
The housing is not a rated pressure vessel; the user must design containment and safe leak control for the process application.
Which documents avoid an approval mismatch for 31000-28-10-00-165-02-02?
Provide the complete probe label, certificate revision, barrier or isolator data, cable parameters and area-classification drawing.
