| 中文摘要 | 介绍了差动涡流式连铸结晶器钢水液位仪的基本原理及构成。仪器可测量0～150mm的钢水液位变化。传感器的核心部分为1个发射线圈和2个接收线圈。信号放大单元采用差动调幅原理,提高了信噪比,扩大了量程。针对结晶器钢水液位测量的特殊性,放大信号再经信号处理单元的若干环节处理成可靠的、适于钢水液位控制的4～20mA线性隔离输出信号。; Presented the basic principle and architecture of the differential eddy-current type continuous-casting mould molten steel level meter. It can measure the molten level meter range of 0～150*!mm. The core of its sensor is made up of one transmitter coil and two receiver coils. The signal amplifier increased signal-to-noise ratio and expanded measurement range by adopting the differential and amplitude-modulating principle. Several parts of the signal processing unit process this amplified signal to linear isolated 4～20*!mA output that is reliable and available for molten steel level control. |
