Sažetak
Systems for low-frequency electromagnetic measurement of metal tube properties (inner diameter, wall thickness and electromagnetic properties) require one or more exciter/pick-up coil pairs. It is essential to model how changes in coil separation and excitation waveform affect the sensitivities to the tube properties. Furthermore, a model, if employable in inverse procedures, would also enable model-based measurement of the tube properties. We present exact analytical model of magnetic field distribution of an exciter coil within the tube. We compare model predictions and previously published results of finite element analysis and experiments. This comparison confirms the applicability of the model in model-based measurements.
