摘要
介绍了一种热电偶冷端温度补偿电路，在（－25～55）℃范围内．该电路冷端温度能自动补偿，其误差不超过±0．5℃，且具有放大热电势信号所需要的增益．
A cold-junction compensation circuit of thermistor is described.In the range of (-25~55)℃. it can compensate the temperature of the cold -junction automatically, whose error will be no more than±0.5℃. Furthermore,the gain to emplify the thermo-emf signal can be available.
