Garanyuk I. Quantum magnetometric converter of direct current

The paper is devoted to elaboration of direct current measurement converters with the frequency output for the current in the range 10 mA-10A, constructed on the basis of quantum magnetometric con-verters, and investigation of their metrological characteristics. Galvanic input separation of some types of converters allows to provide current conversion in high-voltage circuits. Mathematical model of magnetometric converter based on Sz-signal , which allows to model dynamic pro-cesses in measurement converters and current stabilizers on their basis, has been elaborated. Single chan-nel current converter metrological characteristics have been studied, major factors, limitating conversion accuracy, have been discovered, and ways of accuracy increase have been proposed. External magnetic fields influence on differential measurement current converter has been investigated. Current converter and stabilizer, experimental examination of which proved relative error of 0.005% in the current range 10 mA-10A, have been built.
