Circuit's Functions It's common that the strain gauge, magnetic resistance components, semiconductor pressure sensor etc. work in bridge way.This circuit uses MA constant current to unbalance the sensor and uses amplifier to receive.Sensor adopts diffused pressur sensor P-3000S-102G and its voltage range is 0~1KG/CM2.
Circuit's Work Principle OP amplifier A1 is constant current output circuit and the magnitude of the current is determined by reference voltage,VZ and sensing resistance.This circuit uses the maximum magnitude of the variable voltage or the OP amplifier output gets saturated,which makes the circuit unstable.
