摘要
Various embodiments of magnetostrictive transducers (MsTs) for detecting defects in a tubular structure comprise one or more AC coils and one or more magnets. The transducer has a pair of coils (or two coil elements), which are spaced 180 degrees apart relative to the circumference of the tubular structure. Each MsT is selectively operable or configurable so that it may generate either torsional or flexural guided waves.
