随着造纸工业的迅速发展,传统的二位式液控器已不能完全满足生产需要。例如保尔池液位检测、锅炉水位的检测与控制等,它们对液控器的功能、寿命提出了更多的要求。目前,实现这些要求的方案较多,相比之下,采用CMOS电路设计的液控器则更为简单。本文介绍的全集成化数量液控器(以下简称液控器)由6块CMOS数字电路与3块模拟电路组成,具有价廉、低耗、多功能、安装使用方便的优点,广泛应用于对各种导电液体的检测与控制。在造纸行业
With the rapid development of the paper industry, the traditional two-position liquid controller can not fully meet the production needs. For example, the detection of Pillow liquid level, the detection and control of boiler water level, etc. put forward more requirements on the function and life span of the liquid controller. At present, there are many solutions to meet these requirements. In contrast, the liquid controller with CMOS circuit design is simpler. This article describes the fully integrated quantity of the liquid controller (hereinafter referred to as the liquid controller) consists of six CMOS digital circuits and three analog circuits, with the advantages of low cost, low power consumption, multi-function, easy installation and use, widely used in Various conductive liquid detection and control.
