磁致伸缩超声波检测器可用于检测直线移动物体的位置,这是通过超声波传播的时间来计量的.它具有非接触计量的优点.由于超声波传播速度随温度变
Magnetostrictive ultrasonic detector can be used to detect the position of a linear moving object, which is measured by the ultrasonic propagation time. It has the advantage of non-contact measurement. As the ultrasonic propagation velocity with temperature changes
