OVERVIEW<\/strong><\/p>\n

Tank level alarm LS-2\u00a0intended for level alarming of electrically conductive fluid\u00a0\u00a0(petrol-water, oil-water). When set level is reached, controller is switching relay (NO and NC relay contacts can be used).<\/p>\n

LS2 operation principle is based on\u00a0resistance measuring\u00a0of electrically conductive fluid. Sensor contains two\u00a0Stainless Steel\u00a0electrodes,\u00a0when electrodes flood – measuring circuit resistance is changing and LS-2 switching to alarm mode.<\/p>\n

Set of Level alarm LS-2 contains 1 or 2 sensors (by default one), distribution box, wire\u00a0for sensor and control unit.<\/p>\n
