FIELD: measurement technology. SUBSTANCE: electrocapacitive converter to measure levels of liquids incorporates dielectric plate 1 carrying printed electrodes 2 of measurement part on its outer layer and printed electrodes 3 of second measurement part located in same layer of dielectric plate. Electrodes 2 first measurement part are made in the form of trapezia and electrodes 3 of second measurement part are fabricated in the form of trapezia complementing trapezia of electrodes of first measurement part to form constant summary width. Trapezia of electrodes of first measurement part have summary area equal to that of trapezia of second measurement part. In addition converter is fitted with common electrode which surfaces form permanent clearances with reference to dielectric plate and electrodes. Dielectric plate with electrodes and common electrode are manufactured in the form of cylinders placed uniaxially. EFFECT: provision for usage of secondary converters designed for pickups based on differential capacitor, unification of systems of devices. 1 cl, 1 dwg |
