1 原控制电路工作原理简介我公司1996年从德国引进一套窑外分解水泥工艺生产线,所用设备全为进口产品,其原用射频导纳液位计电路如图1。其控制分中央控制室通过计算机接受信号,发出指令且由用户程序控制的集中控制和转换到现场的机旁控制2种方式。 1 original control circuit principle of work Brief introduction Our company introduced from Germany in 1996 a set of kiln decomposition cement production line, the equipment used for all imported products, the original RF admittance level gauge circuit shown in Figure 1. The control of the central control room through the computer to accept the signal, issued by the instructions and controlled by the user program centralized control and converted to the scene machine-side control in 2 ways.
