Product Introduction
The Epro PR6423/005-030-CN+CON021 is a high-precision 8mm Eddy Current Sensor designed for industrial applications requiring accurate measurement of displacement, vibration, and position. The sensor combines the PR6423/005-030-CN measurement head with the CON021 signal conditioning unit, providing a complete system for reliable monitoring of critical machinery.
The sensor operates on the eddy current principle, detecting changes in electrical impedance caused by variations in distance between the sensor tip and conductive targets. These changes are converted into stable, proportional electrical signals by the CON021 unit, allowing for real-time feedback and precise control. The compact 8mm sensor head allows installation in confined spaces without compromising measurement integrity.
This sensor is widely used in applications where non-contact measurement is essential, minimizing wear and maintenance requirements while providing consistent performance under harsh industrial conditions, including high vibration, electromagnetic interference, and wide temperature variations.
