一、涡流式液位检测的概况 结晶器液位检测与控制对于连铸自动化的意义是非常重大的。以节能、高效为最终目的,各钢铁生产大国竞相开展了这一领域的研究工作。 涡流式液位检测是近年来开发较为成功的方法之一。图1是它的检测原理图。标准振荡器产生的高频电流通过由检测线圈和温度补偿线圈组成的反馈放大器,流入检测线圈产生一个高频磁场。当此
First, the profile of eddy current level detection Mold level detection and control for the meaning of continuous casting automation is very important. With the goal of saving energy and increasing efficiency, the major steel producing countries competed in this field. Eddy current level detection is one of the more successful methods developed in recent years. Figure 1 is its test schematic. The high-frequency current generated by the standard oscillator passes through a feedback amplifier consisting of a sense coil and a temperature compensation coil, and flows into the sense coil to generate a high-frequency magnetic field.
