The subject of this master’s thesis is the development of the eddy current rotary probe for tube testing. One must conduct a research of existing solutions to the problem as well as research of submitted patents for rotary probes. List of needed functions and solutions for all the listed functions serve as a basis for generating concepts. This master’s thesis is conducted in association with INETEC and is a basic concept used for further development of their eddy current probe. A 3D model was constructed to generate necessary views as well as technical drawings.
