Synopsis

This paper deals with investigations to determine the layer thickness of electrically conductive coatings on electrically conductive and ferromagnetic steel substrates. For this purpose, an eddy current sensor system with well-known analytical model for ideal conditions is used. Based on this, different coil setups are examined and compared with regard to sensor positioning. A robustness analysis against parameter fluctuations is carried out.
