摘要
针对热电偶冷端补偿问题,提出了2种模拟式补偿方法——电流型模拟集成电路补偿方法和电压型模拟集成电路补偿方法,以及2种数学式补偿方法——查表法和计算法。介绍了这些补偿方法的原理和实现方法,并给出了试验结果,其准确度小于0.02℃。实际应用表明:这些方法简单、实用性强。
According to the problem of compensation of thermocouple, two analog compensation ways——compensation methods of current source analog IC circuit and of voltage source analog IC circuit, and two mathematical compensation ways——table-looking up and calculation methods are described. Their principle and realization methods are introduced, and the experimental results are presented. Its accuracy is less than 0.02℃. The practice shows that the ways are simple and high practicability.
