Emerson Epro CON021 + PR6424/000-110 Eddy Current Sensor System

Description

The Emerson Epro PR6424/000-110 sensor combined with the CON021 signal converter forms a high-accuracy, non-contact eddy current measurement system. It’s designed for radial and axial shaft displacement monitoring, particularly in critical rotating machinery such as turbines, compressors, and motors. This pairing is widely used in predictive maintenance, machine protection, and condition monitoring systems across energy, petrochemical, and heavy industries.
