This study checks the high-temperature durability of the electromagnetic acoustic transducer (EMAT) for pipe wall inning. We inserted EMAT into the oven and measured the 10mm thickness specimen by EMAT about two years. Measurement was carried out by two kinds, a pulse echo method and a pulse echo resonance method. And igh-temperature durability was checked by both of the measuring methods. Compared with the pulse echo method, the ulse echo resonance method of measurement accuracy was better. The filter pro...
