The Bently Nevada 31000-28-05-15-032-03-02 is a Proximity Probe Housing Assembly manufactured by Baker Hughes as part of the 31000/32000 series for externally mounting eddy-current proximity probes on industrial rotating machinery. It is specifically recommended for installations where proximity probes must pass through thin-walled or compact machine casings to monitor internal rotating components, and is typically used for radially mounted transducers measuring vibration, thrust position, or Keyphasor timing in space-constrained environments.

Use of a Proximity probe housing allows external access tothe proximity probe and its extension cable, permitting gapadjustment or probe replacement without disassembly of themachine. The 31000/32000 Proximity Probe Housing Assemblyis made of polyphenylene sulfide (PPS), an advanced, highstrength, thermoplastic with excellent corrosion resistance.Other elements of the housing assembly are made ofcorrosion-resistant stainless steel. The housing can beordered with installed 3300 XL Proximity Probes and a varietyof conduit fittings.

The 31000-28-05-15-032-03-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 31000-28-05-15-032-03-02 ordering code decodes as follows: 31000 designates the inch-based (imperial) housing series; 28 specifies a compact probe configuration (typically a reduced-diameter probe variant optimized for installations with limited internal clearance); 05 indicates a 0.5-meter (20-inch) total probe cable length; 15 denotes a 1.5-inch (38.1 mm) standoff adapter that spaces the housing body away from the machine surface; 032 specifies a 3.2-inch (81.3 mm) probe penetration depth; 03 includes the conduit fitting package with two plugs, one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT stainless steel reducer, and a cable seal grip with grommets for three cable size ranges; and 02 designates a 3/4-14 NPT mounting thread. This configuration is ideal for installations in small bearing housings, pump casings, motor end-bells, and compact gearbox frames where shallow wall thickness and external obstructions require a short penetration depth combined with a standoff extension.
  • Steam Turbines:Radial vibration, thermal growth & rotor stability at bearings
  • Gas Turbines:High-speed dynamics & eccentricity during startup/operation
  • Industrial Turboexpanders:Stability in high-velocity gas expansion
  • Centrifugal Compressors:High-frequency rotor vibration & aerodynamic loading anomalies
  • Axial Compressors:Radial displacement for large multi-stage rotors
  • Boiler Feed Pumps:Avoid bearing failure in critical power plant pumps

Install the Outer Sleeve: Thread and secure the outer sleeve assembly directly into the pre-tapped 3/4-14 NPT machine casing port.
Insert the Probe Sleeve & Set the Gap: Slide the internal probe sleeve down into the casing. Use a digital voltmeter connected to the Proximitor sensor to measure the DC voltage output, adjusting the physical position until you hit the required target electrical gap (typically around -10 VDC for a standard 3300 XL center-range calibration).

FAQs

  • What is 31000-28-05-15-032-03-02?+
    The Bently Nevada 31000-28-05-15-032-03-02 is a configurable Proximity Probe Housing Assembly used to safely secure and protect externally mounted eddy-current proximity sensors in rotating machinery
  • What materials are used to construct the housing?+
    The housing assemblies are primarily made from industrial-grade plastics (such as polyphenylene sulfide) or stainless steel, to withstand the harsh environmental and mechanical conditions found in bearing housings
  • Can I use the 31000 housing to measure shaft axial position?+
    No. For measuring shaft axial position with dual proximity probes, Bently Nevada recommends using the 21022 housing instead
  • Can the housing be used in hazardous environments?+
    Yes. The 31000 housing is designed with country- and product-specific approvals (such as BASEEFA and CSA) to withstand significant impacts and electrostatic dissipation in hazardous areas.
