Bently Nevada 21000-16-05-25-020-04-02 Proximity Probe Housing Assemblies

Description

The 21000-16-05-25-020-04-02 is a Bently Nevada proximity probe housing assembly designed for the secure mounting and protection of eddy-current transducer probes. This assembly provides a robust mechanical interface between the vibration probe and the machine case, ensuring accurate shaft position and vibration measurements in demanding industrial environments.

This specific configuration, featuring Option 16 (Assembly/Material), Option 05 (Conduit Fitting), and Option 25 (Probe Hole), facilitates the integration of standard 3300 and 7200 series proximity probes. The housing acts as an environmental barrier, shielding the probe from lubricants, moisture, and mechanical damage while maintaining the precise air gap required for accurate signal transmission to the Proximitor sensor.

Features

• Designed for 3300 and 7200 series proximity probe integration
• Option 16 material construction for mechanical stability in machine monitoring applications
• Integrated conduit fitting (Option 05) for secure cable routing and protection
• Protects probe sensing tip from mechanical impact and environmental contaminants
• Maintains precise probe-to-target gap for eddy-current measurement integrity

Applications

• Rotating machinery vibration and axial position monitoring
• Fluid film bearing protection
• Compressors, steam turbines, and gas turbines
• Harsh industrial environments requiring sealed probe installation

Installation Guidelines

Ensure the probe housing is mounted perpendicular to the target shaft. Use appropriate thread sealant for the conduit fitting to prevent moisture ingress. Verify that the probe is installed with the correct air gap according to the transducer datasheet. Ensure all grounding and shielding requirements are met for the signal cable to minimize electromagnetic interference.
