An electromagnetic acoustic transducer (EMAT) is presented for excitation and detection of linear polarised shear waves at normal incidence with the use of a horizontal magnetisation of the specimen. The sound field is optimised for the measurement of the wall thickness of steel plates and pipe joints. Special focus is on determining the remaining wall thickness in case of metal loss (e.g. general corrosion, pitting corrosion). If metal loss is present at the transducer-near side, it is not possible to determine the remaining wall thickness because the lift-off of the EMAT sensor caused by the wall thickness reduction may lead to a complete loss of the ultrasonic signal. In order toensure reliable measurement for this case, the EMAT techniq...
