Eddy current bridge converter and analysis of its experimental frequency characteristics

The article deals with a block diagram of the experimental setup for the study of the basic properties of the eddy current transducer (ECT). As an ECT study results, it shows the frequency characteristics of the ECT at five different gaps between the ECT and the control object (СO). An analysis of the frequency characteristics identified three main working area of the ECT. Also in the article are presented depending on the output voltage ECT of the gap between the probe and the CO, at a fixed frequency of the supply voltage. According to the research conclusions are formulated.
