Abstract

The structure of the secondary converter based on AC-bridge for differential sensor, the vector models of its functioning and the ways to adaptively install a quasi-equilibrium state in which the theoretically possible full mutual compensation of common-mode interference signals from the changes of background of conductivity of the buffer solution, even under non-identical conductometric transducers forming a differential pair are discussed. The mathematical expressions for the calculation of diagnostic parameters of a sensor and the necessary parameters of quasi-equilibrium of a bridge are given. References 15, figures 3.
