PRINCIPLE OF MAGNETOSTRICTION

The principles of magnetostriction are used to create a reliable position measurement system for use in industrial environments. Inside the sensor, a torsional strain pulse is induced in a specially designed magnetostrictive waveguide by the momentary interaction of two magnetic fields. One field comes from a magnet located inside a float which moves up and down inside the KMLG magnetic level gauge chamber. The other field is generated from a current pulse which is applied to the waveguide. The interaction between these two magnetic fields produces a strain pulse which travels at sonic speed along the sensor waveguide until the pulse is detected at the head of the transducer. The position of the moving float magnet is precisely determined by measuring the elapsed time between the application of the current pulse and the arrival of the strain pulse. As a result, a reliable position measurement system is created that is capable of providing an accurate and repeatable measurement.

磁致伸缩原理

磁致伸缩原理用于创建用于工业环境的可靠位置测量系统。在传感器内部，通过两个磁场的瞬时相互作用在专门设计的磁致伸缩波导中感应出扭转应变脉冲。一个磁场来自位于浮子内部的磁铁，该浮子在磁性液位计室内上下移动。另一个场由施加到波导的电流脉冲产生。这两个磁场之间的相互作用产生一个应变脉冲，该脉冲沿着传感器波导以声速传播，直到在换能器的头部检测到该脉冲。通过测量电流脉冲的施加和应变脉冲的到达之间经过的时间来精确确定移动浮子磁铁的位置。因此，创建了一个可靠的位置测量系统，能够提供准确和可重复的测量。
