A Simple Adjustment Method of Sweep Rate in Analogue Ultrasonic Testing Instrument

摘要: 在模拟式超声探伤仪扫描速度的调节中, 通常都采用对不同声程处反射回波的反复调节来实现, 比较繁杂。介绍一种依据时基扫描线对反射回波等比缩放原理的方法, 通过分别对不同声程处反射回波的1次调节即可得到所需扫描速度。这种方法简便、高效且准确可靠。

Abstract: In an analogue ultrasonic testing instrument, a sweep rate is usually achieved by repeatedly adjusting echoes that reflected from different sound ways. It is rather complicated. A method based on the principle of time base sweep line geometric scaling of the reflection echoes was presented, and the sweep rate could be realized by adjusting echoes that reflected from different sound ways one time respectively. The method was simple, efficient, accurate and reliable.
