Abstract
Electronic circuit for dimension-measuring device with magneto-resistive electrodes supplying at least one feed voltage for feeding a network of magneto-resistive electrodes and a measuring circuit comprising two differential inputs connected to the network. The measuring circuit uses a rough counter and a fine interpolation circuit for determining from the two sinusoidal input signals received the position of the sensor along the scale. The feed circuit periodically reduces the supplied electric feed voltage so as to temporarily lessen the dissipation of energy in the magneto-resistive electrodes.
