Eddy-Current System for Testing Inner Diameter of Pipes

Resumo

We propose a method for eddy-current testing of the inner diameter of electroconductive pipes. The design of an eddy current transducer is described, as well as an algorithm for converting measurement information signals and the block diagram of a system for testing the inner diameter of pipes that allows testing under conditions of significant radial displacements of the eddy current probe inside the pipe. The effectiveness of the proposed engineering solutions is evaluated.
