Epro CON021+PR6423/01C-010 Eddy Current Vibration Sensor Kit

Product Description

The CON021 + PR6423/01C-010 system from Emerson EPRO is a matched eddy current measurement solution developed for continuous shaft monitoring in high-speed rotating machinery. It integrates a signal conditioning module with a non-contact proximity probe to deliver stable measurement of vibration, displacement, and shaft position under demanding operating conditions.

The architecture is intended for turbine supervisory systems and compressor condition monitoring, where consistent signal fidelity and fast dynamic response are required for protection logic and predictive diagnostics.
