Designing, producing, progaming of electronic devices
OVERVIEW
Tank level alarm LS-2 intended for level alarming of electrically conductive fluid (petrol-water, oil-water). When set level is reached, controller is switching relay (NO and NC relay contacts can be used).
LS2 operation principle is based on resistance measuring of electrically conductive fluid. Sensor contains two Stainless Steel electrodes, when electrodes flood - measuring circuit resistance is changing and LS-2 switching to alarm mode.
Set of Level alarm LS-2 contains 1 or 2 sensors (by default one), distribution box, wire for sensor and control unit.
