EPRO PR6423/003-030-CN | 4-20mA analog | 8mm Eddy Current Sensor Module

The EPRO PR6423/003-030-CN​ is a high-performance 8mm eddy current sensor module designed for critical industrial applications in rotating machinery monitoring. This non-contact sensor utilizes electromagnetic eddy current principles to precisely measure dynamic displacement, position, eccentricity, and speed in steam turbines, gas turbines, compressors, gearboxes, pumps, and fans. The EPRO PR6423/003-030-CN​ features a standard M10×1 threaded installation, making it suitable for conventional industrial scenarios where reliable vibration and displacement monitoring is essential for equipment protection and predictive maintenance.

The EPRO PR6423/003-030-CN​ delivers exceptional measurement accuracy through its advanced eddy current detection technology. The sensor operates by generating an alternating magnetic field that induces eddy currents in the metal target surface, with the attenuation of these currents being proportional to the distance between the sensor and the target. This non-contact measurement principle ensures no mechanical wear and provides long service life, with a sensitivity of 8 V/mm and resolution reaching ±0.5μm, enabling precise monitoring of axial displacement, radial vibration, and shaft eccentricity.
