Electromagnetic Ultrasonic Transducer and On-Line Inspection System Comprising Same |
| 摘要 |
The present disclosure provides an electromagnetic ultrasonic transducer and an on-line inspection system including the transducer. The electromagnetic ultrasonic transducer includes a detection bottom surface and a stopper connected to a sidewall of the electromagnetic ultrasonic transducer; wherein the stopper extends towards the detection bottom surface; a bottom surface of the stopper is lower than the detection bottom surface; a distance “d” between the bottom surface of the stopper and the detection bottom surface is in a range 0 mm<d≦1 mm; the bottom surface of the stopper contacts a surface of an object to be detected in a working state of the electromagnetic ultrasonic transducer. |
