摘要
介绍了一种性能良好的超声波换能器,在现有纵波探头基本结构的基础上,在内部增加高增益放大电路,并利用线路实现发射和接收的转变。实现了发射探头和接收探头可以互换的功能,避免了在应用中发射和接收探头用错而引起的探头损坏。
Introduction was made to a novel ultrasonic transducer which is upgraded from a basic longitudinal wave detector by adding internal high gain amplifier circuits. Furthermore, receiving and emitting in our detector can be switched using a circuit so the receiver and emitter are interchangeable, avoiding detector damage due to misuse of emitter as receiver.
