This study presents the design of an eddy current sensor for accurately measuring the insulation thickness of steel strip armored cables. The sensor utilizes the LDC1612 technology and operates on a non-contact measurement principle, eliminating potential measurement errors associated with contact sensors due to wear and tear. By integrating a laser distance meter, the system achieves precise measurements while ensuring the integrity of the cable insulation. This paper provides a comprehensive description of the sensor's design concept and impl...
