This is the electric thermometer circuit composed of LM134. In the circuit, the voltage or current output by LM134 is in proportion to the thermodynamics temperature, which can be read out on the 100μA meter, the test temperature range of the meter is -55一150℃. The power supply can work even when the voltage is under 1V, but when the precision requirement is high, the power supply should be 1.5V. When the power supply voltage is in the range of 1·5-1·2V, the inaccuracy is about 1℃.
