摘要
详细介绍磁致伸缩原理,深入分析磁致伸缩原理在位移和液位检测中的具体应用,重点讨论磁致伸缩液位传感器的总体结构、波导管的结构、材料的选择以及回波接收的原理并给出了接收装置的方案,分析时间检测原理和方法,提出实现高精度测量传感器的温度补偿和抗干扰措施。通过以上机理分析对传感器的设计和应用提供理论指导。
*'The magnetostrictive principle is introduced,and the magnetostrictive displacement,level sensing principle and the overall structure of the magnetostrictive level sensor are analyzed.Then the structure and the material of the tubular waveguide,the principle of the wavereceiving and the implementation method,the theory of time measuring are discussed,and temperaturecompensate and antidisturbance methods are presented in order to realize high precision measurement.All the theoretic analysis above can provide theoretic guidance for the designing and applying of the sensor.
