| 摘 要： | “喷淋水耦合多探头高能超声动态检测系统”能对各种刚性管材各处的壁厚进行高速、连续的探测,系统检测效果取决于对回波信号的处理.文章探讨了利用放大及逻辑运算等电路处理方法来处理回波信号以获得稳定的壁厚脉冲的新方法,采用这种新方法还可以通过计算机检测系统多图形地显示壁厚曲线、超标报警.

| Abstract: | Multi-probe and high energy dynamic ultrasonic testing system with water-spraying coupling can continuously measure wall thickness of various kinds of pipe at high-speed. But testing effect depends on processing of return wave signal. A new method with amplifier and logic operation circuit for processing of return wave signal is discussed to stabilize wall thickness measuring pulse. Multiple wall thickness curve can be displayed on computer screen, and excess standard warning was provided in this new method. |
