| Abstract: | The influence of a variety of parameters on the linear of the thermometer in the design of the unbal-anced bridge are theoretically analyzed using Matlab software and Origin software. The thermometer was de-signed to obtain 0~100℃range.It was found that it has a good linear relationship between the output voltage of unbalanced bridge and temperature. |
