Bently Nevada 21000-28-05-20-044-04-02 Proximity Probe Housing Assemblies

Description

The 21000-28-05-20-044-04-02 is a 21000-series proximity probe housing assembly designed for the industrial mounting of eddy-current proximity transducers. This assembly provides the necessary mechanical interface between the proximity probe and the machine casing, protecting the transducer while ensuring consistent alignment with the measured shaft or target. The housing assembly integrates multiple configuration options to accommodate specific installation requirements, including probe thread size, mounting orientation, and conduit connection types. This unit is constructed for use in industrial environments requiring environmental protection for the probe lead and connector, effectively isolating the sensor from potential contaminants or moisture within the machine housing.

Features

• Designed for 21000-series transducer integration
• Stainless steel construction for environmental resistance
• Configured with specific probe mounting adapter and conduit interface
• Enables precise gap adjustment and locking of the proximity probe
• Protects probe connections from mechanical stress and external elements

Applications

• Industrial rotating machinery protection systems
• Steam and gas turbine vibration monitoring
• Compressor and pump axial position and radial vibration measurements
• Hydroelectric generator shaft monitoring
• High-temperature or harsh industrial machinery environments
