| Abstract: | In temperature measurement of the thermal resistor, the nonlinearity of thermal resistor, lead resistor and unbalanced bridge may produce errors. In this paper, a kind of improved practical active linear bridge circuit with platinum resistor is used to eliminate the error mentioned above, and the precise temperature measurement can be made. |
