Product Information:

The 31000-00-00-15-047-01-02 is an industrial-grade external eddy current probe housing assembly in the Bently Nevada 31000 series. As a core protective component for modern rotating machinery condition monitoring, it is designed for external installation on high-value equipment such as steam turbines, compressors, large fans, and pump sets, providing a highly flexible physical seal barrier for internal non-contact displacement sensor probes.

The innovative design of the 31000-00-00-15-047-01-02 allows maintenance personnel to adjust the internal probe's measurement gap or replace the probe directly from outside the machine without disassembling the bearing housing or stopping the machine, significantly improving plant operation and maintenance efficiency. Unlike the traditional metal 21000 series, this assembly uses Baker Hughes DAM+3 core material and custom parameters.

The 31000-00-00-15-047-01-02 type protective cover is constructed from advanced polyphenylene sulfide (PPS) high-strength conductive fiber thermoplastic material, while the internal sleeve and exposed screws are made of 304/303 stainless steel, offering excellent mechanical impact resistance and resistance to industrial chemical corrosion.

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 31000-00-00-15-047-01-02 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).

In asset protection and predictive maintenance architectures within large industrial plants, this protective enclosure, when properly assembled in the field and secured to the probe, provides robust environmental protection for sensitive internal sensing components. While not an explosion-proof hard enclosure, it can be safely deployed in intrinsically safe hazardous areas when used with certified sensor systems and intrinsically safe barriers. Its overall design fully complies with American Petroleum Institute (API) 670 standards. The signal cable securely led from the enclosure ultimately connects to a preamplifier and integrates with the Bently Nevada 3500 mechanical protection system, widely used in industries such as power, petrochemicals, and heavy metallurgy, ensuring absolute stability and data accuracy of underlying physical monitoring signals in high-temperature, high-vibration, and high-humidity environments. 

Technical notes

The 31000-00-00-15-047-01-02 is the proximity probe housing assembly for Bently Nevada's 31000 series external eddy current probes. Its body is made of non-metallic glass fiber reinforced polyphenylene sulfide (PPS) conductive thermoplastic (with a matching 304 stainless steel sleeve). The overall design conforms to API 670 standards and has NEMA 4X and IP66 industrial dust and water resistance ratings. Furthermore, it is CENELEC certified for electrostatic dissipation, exhibiting excellent shock and corrosion resistance in harsh environments ranging from -51°C to +105°C. The core technical feature of this model lies in its flexible and customizable "explosion-proof housing" configuration, which does not include probe hardware: the probe option does not include the eddy current probe (-00) and probe cable (-00), but comes with a 1.5-inch high base extension adapter (-15) to avoid external obstruction from the machine housing; a stainless steel sleeve provides a 4.7-inch probe penetration depth (-047); electrical interface accessories include a 3/4-14 NPT connector and two plugs (-01). The entire assembly is secured to the machine via a 3/4-14 NPT thread (-02) on the bottom, providing lightweight yet robust physical and electrical sealing protection for field-customized reverse-mounted eddy current probes (such as the 3300 XL 8mm).
