摘　　要：热电阻温度测量中 ,热电阻的非线性、不平衡电桥的非线性及引线电阻都会给测量带来误差 .本文采用铂电阻改进型实用有源线性化桥路克服了上述误差 。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.

关 键 词：热电阻 温度测量 有源电桥 误差 全补偿方法 铂电阻
