Abstract: A measuring-transducer circuit arrangement suitable for two-line telemetering systems comprises a bridge circuit, a current regulator, a comparator circuit including a reference element and a reference-voltage resistor for controlling the regulator, and a measuring amplifier. The current regulator and the reference element are in series with a diagonal of the bridge circuit.

Abstract: A measuring transducer circuit arrangement comprises a bridge circuit across one diagonal of which the transducer and a measuring amplifier are connected, and the other diagonal of which has a current regulator connected to one terminal adjacent to a compensating resistor in the bridge and a further resistor connected to the other terminal. The current regulator is controlled in dependence on the voltage across the further resistor to maintain this voltage constant.
