Magnetostrictive Expansion Liquid Level Meter

Product Overview

When the magnetostrictive liquid level meter sensor works, the circuit part of the sensor will stimulate a pulsed current

on the waveguide wire, which will generate a pulsed current magnetic field around the waveguide wire when it

propagates along the waveguide wire. The sensor is equipped with a float outside the measuring rod, which can be

moved up and down along the measuring rod as the liquid level changes. Inside the float there is a set of permanent

magnetic rings. When the pulse current magnetic field meets the magnetic field of the magnetic ring generated by the

float, the magnetic field around the float changes so that the waveguide wire made of magnetostrictive material

generates a torsional wave pulse at the position of the float, which travels back along the waveguide wire at a fixed

velocity and is detected by the detection mechanism. By measuring the time difference between the pulse current and

the torsion wave, the location where the float is located, i.e. the liquid level, can be precisely determined.

检出机构检出。通过测量脉冲电流与扭转波的时间差可以精确地确定浮子所在的位置，即液面的位置。

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

在浮子内部有一组永久磁环。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

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，此浮子可以沿测杆随液位的变化而上下移动。

磁致伸缩液位计传感器工作时，传感器的电路部分将在波导丝上激励出脉冲电流，该电流沿波导丝传播时会
