论述了导电式水位检测计的工作原理。在水池的不同深度分别插入电极 ,由于水的导电性 ,这些电极会随着水深的变化 ,分别呈现绝缘或导通状态。电极将检测结果表示为不同的电压信号 ,从而显示水位高低并在水满时报警 The working principle of the conductive water level detector is discussed. The electrodes are inserted at different depths of the pool. Due to the conductivity of the water, these electrodes exhibit insulation or on-state, respectively, as the water depth changes. The electrodes represent the test result as a different voltage signal, which shows the level of the water level and alarms when the water is full
