21000-16-10-00-077-03-02 Bent1y Nevada 21000 Housing Assembly

Product Overview

The 21000-16-10-00-077-03-02 is a specialized external mounting assembly designed to facilitate the installation of proximity probes in machinery where internal mounting is impractical or inaccessible. By providing a rigid, explosion-proof enclosure, this housing ensures that the 3300 XL 8mm probe maintains precise gap alignment against the target shaft. It effectively shields the sensor from mechanical damage, environmental contaminants, and hazardous atmosphere exposure, making it a critical component for radial vibration and axial thrust measurements in high-pressure pumps and steam turbines.
