Thermistor electronic thermometer circuit diagram


Posted on Feb 4, 2014

The thermistor RT and R1, R2, R3 and RP1 form a temperature measurement bridge. When temperature is at 20 ?, using R1, R3 and adjusting RP1 can allow bridge to keep balance. When temperature rises, the resistance of the thermistor RT reduces, the bridge in an unbalanced state, the imbalanced voltage output by bridge is amplified by operational amplifier, th..
