Epro CON021+PR6424/013-140 Eddy Current Sensor

Product Description

The PR6424/013-140 + CON021 system by Emerson Epro is a precision-engineered eddy-current measurement solution for continuous monitoring of shaft movement in rotating equipment. It combines a compact proximity probe with a dedicated signal converter to deliver stable and accurate measurements of vibration, displacement, and shaft position.

The probe operates on a non-contact electromagnetic principle, eliminating mechanical wear while ensuring high repeatability. The CON021 module processes the raw signal, applying amplification and filtering before providing standardized outputs suitable for integration with PLC, DCS, and condition monitoring platforms such as Emerson AMS.

This system is optimized for use in electrically noisy and mechanically demanding industrial environments.
