Description：

The Bently Nevada 31000-00-00-15-051-01-02 Proximity Probe Housing Assembly is part of the 31000/32000 Series externally mounted proximity probe housing assemblies, designed for installing proximity probes through machine casings on critical rotating equipment. It provides secure mechanical support for the probe while maintaining accurate positioning for reliable vibration and shaft position monitoring.

This housing assembly is typically used with radially mounted proximity transducers for applications including shaft vibration measurement and Keyphasor® reference monitoring. By providing a protected mounting arrangement, it helps maintain stable probe alignment and supports continuous condition monitoring of rotating machinery.

When installed together with an approved proximity transducer system and appropriate intrinsically safe (I.S.) barriers, this housing assembly can be used in intrinsically safe hazardous area applications. It is suitable for environments such as oil and gas facilities, petrochemical plants, and power generation equipment where hazardous area certification requirements apply.

Product Applications

Oil and Gas: Used for monitoring bearing vibration and axial displacement in large centrifugal and reciprocating natural gas compressors, preventing impeller impact on the casing under high-speed rotation.

Power Generation: In steam turbine generator sets of thermal or nuclear power plants, this protective enclosure protects sensors monitoring rotor thermal expansion, axial creep, and oil film oscillation.

Petrochemicals: Used in various large pumps and compressors (e.g., cracked gas compressors, quenching pumps, and high-pressure feedwater pumps) in oil refineries and ethylene plants.

Metallurgy and Heavy Industry: Blast furnace blowers, large exhaust fans, and rolling mill drive chains.
