摘要
论述了热电阻测温时因工作电流随热电阻阻值变化所带来的误差,提出了软件技术可以补偿这种误差。根据已设计定型的转换电路完成一个新的修正分度表输入内存,可在全量程范围实现较高转换精度。
The error caused by current changing along with the resistance varying of RTDs in RTD temperature measurement can be compensated by software. By storaging a new modified scale into the memory in accrdance with the result from a proven converting circuit, high converting accuracy in full scale range can be accomplished.
