Rail investigating ultrasonic transducer |
摘要 |
An ultrasonic railhead investigating apparatus is described wherein a side looking transducer is used with a lens to focus the beam in a manner whereby rail defects in the sides of rail head are more readily detected. In one form of the invention a side rail investigating transducer is provided with a curved emitting surface and so located as to place the focused acoustic beam between a side of the rail and the rail center. The curved emitting surface can be part of a cylindrical surface aligned parallel with the longitudinal axis of the rail or a spherically shaped emitting surface to provide a conically shaped beam for investigating the side of a rail.
