This picture is temperature control circuit of transistor temperature sensor.In this circuit,the voltage and tempreature between the base and emitter is inversely proportional.RP2, R3 ,r4-g9 and it consititute bridge road together.A1 amplifies the unbalanced voltage of the bridge road.A1 outputs 100 mV votlage u when the temperature changes 1 ℃.Please adjust RP2 and when the temperature is 0℃,A1 outputs 0V.Please adjust RP2 and when the temperature is 1℃,A1 outputs 100mV.
