Product Introduction
The Epro PR6423/010-010-CN eddy current sensor, combined with the CON021/914-100 converter, forms a robust proximity measurement system widely used in critical industrial monitoring applications. Developed by Epro, a trusted name under Emerson, this 8mm eddy current sensor is tailored for non-contact measurement of shaft displacement, vibration, and axial position in rotating machinery. With its superior durability, high-temperature tolerance, and seamless integration into vibration monitoring systems, it ensures accurate and real-time data for predictive maintenance and machine protection strategies.
This system is typically employed in turbines, compressors, pumps, and gearboxes in industries such as oil & gas, power generation, and petrochemical manufacturing.
