Product Information:

The Bently Nevada 31000-00-00-15-050-02-02 is a high-strength, non-metallic eddy current probe external mounting protective housing assembly designed and manufactured by Bently Nevada (a brand under Baker Hughes). As a core physical external protection component in rotating machinery condition monitoring and protection loops, it is typically securely mounted on the housings of high-value equipment such as industrial steam turbines, centrifugal compressors, and heavy-duty fans.

The Bently Nevada 31000-00-00-15-050-02-02 allows field maintenance personnel to safely adjust, calibrate, or completely replace internal sensors directly from outside the equipment without disassembling bearing housings or shutting down the equipment, providing a highly available field physical hard-shell barrier for continuous vibration and displacement monitoring of large turbine equipment.

In terms of industrial applications and reliability, the 31000-00-00-15-050-02-02 meets high standards of industrial protection and HazLoc hazardous area compliance specifications. This product has passed CSA 4X and IP66 all-weather dustproof, waterproof, and high-pressure spray certifications.

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 31000-00-00-15-050-02-02 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).

Its main body is precision-manufactured using conductive PPS material, which contains conductive fibers. This material not only has superior resistance to acids, alkalis, and salt spray corrosion compared to traditional metal casings, but also meets the stringent explosion-proof specifications of the EU CENELEC (EN50014 standard) regarding electrostatic dissipation of plastic materials in hazardous areas. Internally, neoprene O-rings ensure perfect physical airtightness, completely preventing high-temperature oil mist leakage from the machine's bearing housings, fully complying with the American Petroleum Institute (API) 670 standard recommendations.
