Abstract
Датчик для измерения электропроводимости, предпочтительно имеющий конструкцию с парой магнитных сердечников с обмоточным проводом первичной обмотки, намотанной вокруг общего элемента обоих сердечников, и обмоточным проводом вторичной обмотки вокруг неиспользуемой совместно секции каждого сердечника. Когда часть одного сердечника погружена в жидкость и ток подают на первичную обмотку, измерения, снимаемые на вторичной обмотке, позволяют определить электропроводимость жидкости. Аналогичная конструкция может быть использована для измерения уровня жидкости и определения полного сопротивления.
