Product Information:

The 31000-26-05-00-040-01-02 is a fiberglass-reinforced eddy current probe housing assembly in the Bently Nevada 31000 series. As an external protection device for large rotating machinery such as compressors, blowers, and small to medium-sized pump sets, it fully complies with the API 670 industry standard.

The Bently Nevada 31000-26-05-00-040-01-02 allows field engineers to precisely install, adjust clearances, or hot-swap internal proximity probes directly from the outside of the equipment housing when the equipment is not running or under safe maintenance, without requiring extensive disassembly of the housing, thus significantly improving the convenience of daily operation and maintenance.

The Bently Nevada 31000-26-05-00-040-01-02 housing has an IP66/NEMA 4X fully sealed oil and water resistance rating. Because it integrates a 3300 NSv measurement system designed specifically for confined spaces, non-magnetic stainless steel, or small shaft diameters (less than 51 mm), it is widely used in axial and radial vibration and axial displacement monitoring circuits for diaphragm bearing housings in high-speed centrifugal air compressors, refrigeration compressors, and air separators.

Features:

  • Proximity Probe Housing Assemblies
  • 31000 and 32000 Proximity Probe Housing Assemblies
  • The 31000/32000 Proximity Probe Housing Assembly is made of polyphenylene sulfide (PPS)
When proximity probes need to be mounted inside a machine housing, the 31000/32000 type proximity probe housing assembly is recommended. This assembly is typically used for radially mounted sensors, whether for vibration or key phase measurements. Using a proximity probe housing allows for easy external access to the proximity probe and its extension cables, enabling gap adjustment or probe replacement without disassembling the machine.

The 31000/32000 type proximity probe housing assembly is made of polyphenylene sulfide (PPS), an advanced high-strength thermoplastic material with excellent corrosion resistance. Other components of the housing assembly are made of corrosion-resistant stainless steel. Versions of this housing assembly pre-installed with the 3300 XL type proximity probe and various conduit fittings are available by order.

The 31000-26-05-00-040-01-02 Bently Nevada Proximity Probe Housing Assemblies may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 31000/32000 Proximity Probe Housing Assembly is designed to seal differential pressure between the probe tip and the housing main body when used with a 3300 XL 8 mm probe. The sealing material internal to the probe case consists of a Viton O-ring; the Oring between the sleeve and the housing is a Neoprene O-ring. The plastic housing is certified to seal against hose-directed water according to NEMA 4X and IP66 standards but is not designed to resist internal or external pressure.
