Product Description
u The Emerson PR6423/002-000 CON021 (commonly referred to as the EPRO PR6423) is a high-performance, linear eddy current displacement sensor engineered for non-contact, continuous measurement of rotating machinery. Operating on high-frequency eddy current principles, it accurately monitors static parameters (such as shaft position and eccentricity) and dynamic parameters (such as radial vibration) without physical contact.
u As a core component of Emerson's globally recognized EPRO series, this sensor is purpose-built to comply with stringent API 670 standards. It is typically paired with the CON021 signal converter for precise signal linearization and temperature compensation, converting raw impedance changes into standard signals for integration into machinery protection platforms like the Emerson CSI 6500 or AMS 6500.
