FIELD: oil products inspection.
SUBSTANCE: indicator has self-excited oscillator, capacitive pick-up provided with thermo-sensitive resistor, scaling amplifier. Commuting cascades are connected to output of scaling amplifier. Number of cascades equals to number of brands of inspected petrol. Any cascade has two-level comparator and AND-NOT gate. Light-emitting diodes are used as indictors which are connected to outputs of all cascades.
EFFECT: simplified design of circuit diagram.
