FIELD: electric measurement technology; electric current measurements. ^ SUBSTANCE: proposed current-to-pulse-frequency converter has reference-voltage supply whose output is connected to one input of electronic commutator, integrating capacitor, and threshold element. Electronic commutator is built of four electronic switches connected into bridge circuit with integrating capacitor and threshold element inputs connected across two opposite terminals of bridge; direct and inverting outputs of threshold element are connected to control inputs of electronic commutator whose other input functions as converter input; direct output of threshold element functions as converter output. ^ EFFECT: enhanced precision of conversion. ^ 1 cl, 2 dwg |
