关于液位自控装置,许多报刊都有介绍,但检测液位的电极多数使用金属,电极上加有交、直流电,长期使用中容易被腐蚀;在高温环境中,甩极间绝缘也将受到影响,这些因素会影响装置的可靠性。而使用干簧管作液位检测元件,则可解决上述问题。 装置的电路原理如附图所示。在附图中容器的下
About liquid level control device, many newspapers have introduced, but the detection of liquid level electrode most of the use of metal, the electrode plus AC, DC, long-term use of easily corroded; in high temperature environment, throw rejection will also be affected , These factors will affect the reliability of the device. The use of reed switches for liquid level detection components, you can solve the above problems. The circuit of the device is shown in the attached figure. In the figure below the container
