THE STATE AND DEVELOPMENT TRENDS OF EDDY CURRENT SENSORS

Background. The relevance of the topic is due to the variety of applications and designs of eddy current sensors. The information contained in the article corresponds to the current state of methods and means of technical measurements and reflects the latest achievements of science and technology in the field under consideration. The purpose of the work is an analytical review of modern types, description of applications and consideration of trends in the development of eddy current sensors. Materials and methods. Using the eddy current method of non-destructive testing, it is possible to assess the condition and mechanical properties of materials, determine the thickness of the layer, identify defects in the form of discontinuities, measure the distance between fast-moving objects, etc. Results and conclusions. The eddy current method of non-destructive testing has tangible advantages over other methods, namely: accuracy of the results obtained, multiparameterization, non-contact, weak influence of environmental factors, automation.
