摘要
文中对铂电阻的测温电路进行了原理分析,并利用契比雪夫定理进行最佳逼近的参数优化设计方法,确定测温电路中元件参数,简化了电路调试过程,提高了测量的精度。
Platinum-resistance has been applied in temperature measurement system very widely.The theory of measurement circuit has bend analyzed.Then all parts' parameters are optimized by Chebykshev theorem,one of optimal approximation theories.So the debugging process is simplified and the measurement precision was improved.
