概要

Abstract: An electromagnetic acoustic transducer (EMAT) design using an air-cored solenoid coil as a pulsed electromagnet is proposed for high-temperature non-contact monitoring, and prototype probe is evaluated through performance test in the range from room temperature to 700°C. The coil generates a biasing magnetic field that enables the device to overcome the Curie temperature limitations of conventional EMATs. Pulsed echo measurements of carbon steel are performed at high temperatures, and verify EMAT operation at higher temperatures.
