The paper proposes a modification of the method using eddy currents to measure the resistance of thin layers of conductors. The object of research is the coating of glass substrate for use in construction. The proposed method allows performing measurements at selected points in large glass panes without damage layer. Developed test procedures and way how to calculate the impedance of a layer base on resonance curves. In addition, the author has proposed a means to verify the results obtained by means of model tests specifically shaped layers test. An extensive analysis of errors and methods of measurement of uncertainty with regard to the results obtained in the modeling were also carried out, as well as actual measurements. The sensor working in serial resonance provides high sensitivity and an increase in the resistance to interference from external factors, which are extremely important for the use of the equipment in industrial conditions. Designed and manufactured measurement system allows you to move the sensor away from a thin layer to a distance of 5 mm, and in the case of layers with high conductivity up to 20 mm. The obtained results confirmed assumptions of the pre-thesis work and the usefulness of the method developed to measure the resistance of thin layers derived from ion technologies.
