Abstract
A two-wire displacement converter for converting minute mechanical displacements to a DC output signal requiring no precision components yet providing a highly accurate output signal. A pair of first and second AC-excited reactive elements is provided, at least one of which has an impedance which varies in response to the mechanical displacement. DC signals proportional to the impedances of the first and second impedance elements are supplied to a differential amplifier, which produces an output signal having a magnitude related to the difference between the first and second current signals, and thus indicative of the amount of mechanical displacement. A current regulator circuit maintains a sum of a third current signal through a third reactive impedance element having a fixed impedance and at least one of the first and second current signals at a predetermined, fixed value.
