More Information

Overview Manuals Configuration Review Installation Safety Boundaries Product Applications

Features:

  • External probe access: The housing supports gap adjustment and probe service without machine disassembly.
  • Configured 8 mm sensing path: The assembly includes a multiple-approval probe and 1.0 m cable.
  • Environmental enclosure: Type 4X and IP66 construction protects the installed components when correctly assembled.
The 31000 housing is intended for through-case radial-vibration or phase-reference probe installations.

Its standoff, penetration, fitting set and mounting thread are encoded in the complete assembly number and must be retained at replacement.

The enclosure does not replace process-pressure containment or an explosion-proof housing where those protections are required.

Apter Power can help confirm the Bently Nevada 31000-28-10-15-040-03-02 probe, sleeve geometry, fitting set and machine-case thread before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Probe choice: Confirm the included multiple-approval 3300 XL 8 mm probe matches the monitoring channel.
  • Standoff: Verify the 1.5-inch adapter places the housing outside insulation and other machine obstructions.
  • Penetration: Reconcile the 4.0-inch probe penetration with the machine-case and target geometry.
  • Fittings: Confirm the option 03 plugs, reducer and cable-seal grip suit the planned conduit route.
  • Outer sleeve: Install the 3/4-14 NPT sleeve in the prepared machine-case opening using the approved sealing practice.
  • Probe gap: Insert the probe sleeve, set the electrical gap and secure the retainer before final cable routing.
  • Housing closure: Seal unused holes and tighten the cover hardware while preserving cable bend radius.
  • Sleeve support: Add support near the probe where combined standoff and penetration exceed the documented limit.
  • Pressure boundary: Do not treat this assembly as pressure-rated or explosion-proof containment.
  • Leak control: The machine design must safely contain liquids or gases if leakage occurs through the probe path.
  • Measurement validity: For radial vibration, verify the machine casing is affixed to the bearing.
  • Axial arrangement: Use the manufacturer-specified alternative housing for dual-probe axial-position measurement.
  • Radial shaft vibration: Provides an externally serviceable probe path through a machine case.
  • Keyphasor reference: Houses the probe used to observe a phase-reference target.
  • API 670 installations: Supports externally mounted proximity-probe housing practice within the documented boundary.
  • Maintenance access: Allows probe adjustment or replacement without opening the monitored machine.
Description
31000-28-10-15-040-03-02 provides an externally accessible Bently Nevada proximity-probe housing for radial vibration or Keyphasor installations through a machine case, allowing probe-gap adjustment or replacement without opening the machine.

The configuration of 31000-28-10-15-040-03-02 includes a multiple-approval 3300 XL 8 mm probe, a 1.0 m cable, a 1.5-inch standoff, 4.0-inch penetration, fitting set 03 and a 3/4-14 NPT mounting thread.

Although 31000-28-10-15-040-03-02 carries Type 4X and IP66 protection, the housing provides mechanical and environmental protection rather than an explosion-proof enclosure, so pressure containment and hazardous-area protection remain system-level responsibilities.

Technical notes
31000-28-10-15-040-03-02 is not an explosion-proof or pressure-rated housing. Install it only where the machine case is fixed to the bearing for valid relative-vibration measurement, contain any process leakage by design, support long sleeves, and use housing 21022 instead for dual-probe axial-position arrangements. Tighten the retaining nut to the published torque.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can 31000-28-10-15-040-03-02 be treated as an explosion-proof enclosure because it has hazardous-area probe approvals?
No. The assembly provides mechanical and environmental protection only. Use the manufacturer-specified explosion-proof housing where the area design requires that enclosure type.
A radial-vibration reading from 31000-28-10-15-040-03-02 changes with casing movement. What installation condition matters?
Confirm the machine casing is affixed to the bearing. Relative shaft vibration cannot be interpreted correctly if the probe housing moves independently of the bearing reference.
Does 31000-28-10-15-040-03-02 include the proximity probe or only the empty housing?
It includes option 28, a multiple-approval 3300 XL 8 mm probe, plus the 1.0 m cable defined by option 10. Verify the received assembly scope against the full code.
The machine requires two axial probes. Is 31000-28-10-15-040-03-02 the recommended housing?
No. Baker Hughes directs dual-probe shaft axial-position arrangements to housing 21022. Use the correct housing and drawing for that application.
A conduit route needs a 1/2-inch connection. What does fitting option 03 on 31000-28-10-15-040-03-02 provide?
It includes a 3/4-14 NPT fitting, a stainless 3/4-14 to 1/2-14 NPT reducer, two plugs and a cable-seal grip set for the listed cable ranges.
Can 31000-28-10-15-040-03-02 contain process pressure if the probe seal leaks?
No. The user must provide safe liquid and gas containment for a leakage event. The housing is certified for environmental ingress protection, not process-pressure containment.
