Product Information:

The 31000-00-00-15-039-01-02 is an industrial-grade external eddy current probe housing assembly in the Bently Nevada 31000 series. As an indispensable auxiliary hardware component in precision rotating machinery condition monitoring, it is specifically designed for external installation on high-value equipment such as steam turbines, centrifugal compressors, and large industrial fans.

The core design advantage of the 31000-00-00-15-039-01-02 is that field maintenance personnel can safely adjust the internal probe's measurement gap or perform component maintenance directly from the outside of the machine without disassembling the machine's bearing housing or stopping the machine, thus significantly reducing equipment downtime costs and maintenance risks.

Unlike the traditional cast aluminum 21000 series, the 31000-00-00-15-039-01-02 features a main body made of advanced polyphenylene sulfide (PPS) high-strength conductive fiber thermoplastic material, while the internal sleeves and key fasteners are made of 304/303 stainless steel, offering superior resistance to industrial chemical corrosion and mechanical impact.

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 31000-00-00-15-039-01-02 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).

Within a comprehensive plant asset protection and predictive maintenance architecture, this protective enclosure, once properly assembled and secured to the probe in the field, provides a high level of environmental sealing protection for internally sensitive sensing elements. While the polymer enclosure itself is not explosion-proof, it can be safely deployed in intrinsically safe hazardous areas when used with certified probe systems and intrinsically safe barriers.
 
Its overall mechanical construction fully complies with American Petroleum Institute (API) 670 standards. The signal cable safely exiting the enclosure is ultimately connected via an extension cable to a preamplifier and integrated into the Bently Nevada 3500 mechanical protection system. This system is widely used in the power, petrochemical, and heavy metallurgical industries to ensure absolute stability of underlying physical monitoring signals in high-temperature, high-vibration, and high-humidity environments.
