磁致伸缩液位计信号拾取方法的研究与实现

摘要

Based on comparing some methods to detect torsion wave signals,an appropriate signal pick-up technology-piezoelectric ceramics was proposed,including the design of adaptive circuit to deal with torsion wave attenuation.%采用磁致伸缩液位变送器对几种扭转波信号的检测方法进行比较,给出一种简便的信号拾取技术——压电陶瓷法,同时设计自适应电路解决了扭转波衰减的问题.
