摘要
介绍如何利用单片机对热电偶测量装置中对热电偶的非线性,冷端温度的补偿,以及运算放大器零漂和数值转换关系Av实时测出的处理方法,提高了温度控制领域中温度的测量精度。
This article introduces how to deal with the thermocouple non-lineation in the thermocouple temperature survey using the single-chip microprocessor. It also deals with the compensation of the cold end temperature, the ze-ro drift of the operational amplifier and the management method of the gain rectifying.
