Abstract

Guided waves can be used for the thickness measurement of a stainless steel vessel. Commonly used piezoelectric transducers for guided wave generation are often not suitable because of potential couplant contamination. Therefore, a non-contact electromagnetic acoustic transducer (EMAT) was used in this study for non-contact measurement. A sample stainless plate with four different thicknesses was made for the study. A direct and an indirect measurement method based on the relationship between the peak frequency shift and the thickness change were developed. Great accuracy for the thickness measurement was realised.
