Epro PR6423/10R-111 8mm Eddy Current Sensor

The Epro PR6423/10R-111 is an 8mm eddy current sensor, specifically designed for non-contact vibration and axial displacement measurement in rotating machinery such as turbines, compressors, pumps, and motors. Manufactured by EPRO, a brand under PHOENIX CONTACT, this sensor is a part of the PR6423 series — a widely adopted and reliable family of probes used in condition monitoring systems for industrial applications.

This probe operates based on the eddy current principle, which allows it to accurately detect the position and movement of metallic targets without physical contact. It is typically used in conjunction with CON011 or CON021 converters and compatible monitoring systems like MMS6000, MMS8000, and Bently Nevada monitors.

The PR6423/10R-111 is tailored for rugged environments, providing excellent thermal stability, corrosion resistance, and long-term operational reliability. With a standardized probe tip diameter of 8mm, this model ensures high-precision measurements and is suitable for general-purpose industrial machine protection.
