The new sensor system by combining of a piezoelectric thin-film multilayer ultrasonic element and an electromagnetic induction coil could be driven from 20cm far exceeding the sensor by using a drive equipment which consists of an electromagnetic induction coil and a high power electric transmitting device, as a result of electromagnetic induction coil specification optimization. Then there was no change in the detection sensitivity, when the high temperature experiment up to 400 degrees is conducted and only a coil's is heated. Next, when a piezoelectric thin film type ultrasonic sensor was heated simultaneously, the sensitivity fell down, but the sufficient receiving signal intensity was obtained. Next, it was possible to successfully receive a guided wave by electromagnetic induction method by attaching a piezoelectric transducer at regular intervals on test the pipe to circumferential direction to detect the through-holes of 10mm diameter.

通过优化电磁感应线圈的规格，利用电磁感应线圈和大功率电发射装置组成的驱动装置，将压电薄膜多层超声元件和电磁感应线圈相结合，实现了远超传感器20 cm的驱动。然后，当进行高达400度的高温实验并且仅加热线圈时，检测灵敏度没有变化。接着，当同时加热压电薄膜型超声波传感器时，灵敏度下降，但获得足够的接收信号强度。接下来，通过在圆周方向上测试管道时以规则间隔附接压电换能器以检测10mm直径的通孔，可以通过电磁感应方法成功地接收导波。
