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.
