| Abstract: | A practical interface Circuit for transducers based-on bridge measurement is described in this paper. The circuit is of such features as constant current power supply for the bridge,high accuracy amplifier in primary stage, operational amplifier in end stage. The amplified bipolar output voltage doubles the resolution. |
