| 摘 要： | 为了减小热电偶温度传感器的非线性输出误差，介绍了一种分段线性化补偿原理，给出相应的补偿电路和电路分析。实验结果表明：经补偿后在（0-1000）℃范围内，其电压-温度系数约为0．041mV／℃，非线性误差优于0．4％。

| Abstract: | In order to decrease nonlinearity output errors of thermocouple sensors, a sort of piecewise linearization method for signal compensation is provided, including its working principle, the circuit and circuit analysis . The laboratory results show that the voltage-temperature factor is about 0.041 mV/℃ and nonlinearity output error is less than 0.4% during 0-100 degree centigrade of temperature compensation range after compensation processing |
