基于压力传感器实现的液位控制系统的设计

Based on a pressure sensor to achieve the level control system design

文章介绍一种基于压力传感器实现的液位控制器的设计方法,该控制器以单片机为核心,通过外围硬件电路来达到实现控制的目的。可根据需要设定液位控制高度,同时具备报警、高度显示等功能,由于增加了气体压力传感器,使其具有与液面不接触的特点,可用于有毒、腐蚀性液体液位的控制,具有较高的研究价值。该控制器不仅可用于学校进行教学研究,还可用于生产实际,是目前比较缺少的一种产品。

A single-chip microcomputer-based controller to achieve the level of the design method, the single-chip controller as the core, through the external hardware control circuit to achieve the control.It can set level control height, at the same time have functionality of alarm and displaying a high degree, due to an increase of gas pressure sensor, so it will have characteristic of no contact with the liquid surface, can be used for level control of toxic, corrosive liquid and have high research value. The controller can be used not only for teaching and research schools, but also for the reality of production and is a scarce product.
