倍加福P+F电极式液位测量仪

倍加福P+F电极式液位测量仪
详细介绍:

测量原理

导电液体的很普遍。一旦液体达到固定高度的电极时,液体使两个电极(或者容器与电极之间)之间的DC自由交变电流电路闭合,电流的突变产生一个开关信号。 可以很好的检测酸、碱和水溶液。非抗腐蚀材质的探头不能检测强腐蚀性液体。易燃液位如燃料、汽油和溶剂是非导电的,不适用于该测量原理。

工作模式

两个电极被安装在受检测的导电液体表面,当液位上升到一定位置两根电极接触到液体,导通的继电器通过两根电极和液体产生一个开关信号。 液体最小导电率必须为10μS/cm。这些情况下除了纯溶剂外,必须是典型的导电液体,如水、酸和碱。 如果需要多个开关点,就用相关的多杆电极。为避免液体中的电气影响,被测电流用无直流信号的交流电,这由电极开关放大器或变换器产生。 分界面液位检测用这种方法测量既经济又方便,特别是用于原油和汽油分界面,水和非导电液体分界面。
