Split D Differential Probe Model Validation Using an Impedance Analyzer (Preprint)

Benchmark and validation studies are presented that quantify the accuracy of computational models. An important factor in these studies is the ability to compare simulated impedance results with experimental data. In a majority of differential benchmark studies the data acquisition is handled by a commercial eddy current instrument which allow for only a relative comparison of the data. In this study a novel data acquisition system allows for the collection of impedance data for differential probes. Details about the data collection, experimental procedure, model construction, and data comparison will be presented.
