This multiplexing circuit arrangement includes a multiple of sensor pairs connected in two arms of an electric bridge circuit across which a differential amplifying circuit is coupled for sensing the difference in signal at each pair of sensors. The pairs of sensors are connected one pair at a time by means of an FET (field-effect transistor) multiplexing switching arrangement.
