特点                                                                                                                              

传感器工作时,传感器的电路部分讲在波导丝上激励出脉冲电流,该电流沿波导丝传播时会在波导丝的周围产生脉冲电流磁场。在传感器测杆外配有一浮子,此浮子内部有一组磁环。当脉冲电流磁场与浮子产生的磁环磁场相遇时,浮子周围的磁场发生改变从而使得由磁致伸缩材料做成的波导丝在浮子所在的位置产生一个扭转波脉冲:这个脉冲以固定的速度沿波导丝传回并由检测机检出。通过测量脉冲电流与扭转波的时间差可以地确定浮子所在的位置,即液面的位置。
