out-of-limit

An apparatus is designed to detect liquid level limit in transparent with a laser beam across the transparent vessel at the set liquid level.

设计了一种透明容器液位越限报警装置,该装置利用光电检测方式工作:激光器照射透明容器的设定报警液面位置,光线穿越容器出射到光电二极管上 设定位置液体的有无将改变该液位的折射率,从而改变光线的出射角,引起光电二极管接收光强的变化,检测电路侦测到这种变化,接通本地及遥控装置进行报警 经实验证明该装置工作可靠,灵敏度高,可应用于医疗及工业液位控制
