Epro CON021+PR6423/011-110-CN Eddy Current Sensor System

Product Description

The CON021 + PR6423/011-110-CN package from Emerson EPRO is a calibrated eddy current measurement system developed for continuous monitoring of shaft dynamics in rotating equipment. This configuration integrates a signal converter with an 8 mm proximity probe, enabling accurate, non-contact measurement of displacement, vibration, and shaft position.

The converter unit processes raw sensor signals into stable analog outputs, making the system suitable for machinery protection systems and condition monitoring platforms in critical industrial environments.
