Testing double current bridges for resistance measurements
Adam Idźkowski, Jarosław Makal · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2005
A new type of circuit-bridge supplied unconventionally by two current sources will be discussed. An idea of this circuit has been suggested in some publications by Zygmunt Warsza under a name: double current bridge. The bridge conditioner makes possible to operate with the resistive sensors and to measure one, two or four parameters at one time. In this paper the relations between the arm currents and voltages of DC current supply bridges will be simulated. Also a sensitivity and a nonlinearity of these circuits will be discussed.
