In article raise questions of synthesis of equivalent equivalent circuits the eddy current sensors of movements according to frequency characteristics of an immitance of a bipolar chain of the sensor . Possibility of increase of informative ability of VD is shown. The technique of synthesis of an equivalent circuit and example of construction optimum on sensitivity of a measuring chain of quasidifferential VD of movements is given. The offered technique of synthesis of a two-element equivalent circuit of VD allowed to determine not informative parameter and to eliminate it by means of the circuitry decision and thus to lower overall dimensions of VD.
