FIELD: measurement technology, construction, power engineering, food industry. SUBSTANCE: level gauge includes electric motor with reduction gear, drum, lead-and-line in the form of rope with weight, transducer of turn of drum, electromagnetic latch, controller, elements of loading of electric motor in the form of resistor and diode connected in series and linked in parallel to winding of electric motor, current pickup of electric motor and limiter of travel of load. First input of controller is connected to output of transducer of angle of turn of drum, second input of controller is connected to current pickup, first output of controller is connected via winding of electric motor to current pickup, second output of controller is connected to electromagnetic latch. Controller incorporates pulse counter, timer, indicator, comparator and control unit. EFFECT: increased functional reliability. 1 cl, 1 dwg
