Emerson Epro CON021+PR6423/010-100 Eddy Current Sensor System

Description

This system combines the CON021 signal converter with the PR6423/010-100 eddy current sensor, forming a robust solution for non-contact measurement of shaft vibration, position, and displacement. It’s widely deployed in turbomachinery, compressors, pumps, and gearboxes where real-time condition monitoring is critical.
