摘要
】根据铂热电阻不平衡电桥测温的原理,进行了测温误差分析,利用最小二乘法,给出了一组多项式公式。很好地解决了铂热电阻不平衡电桥法测温方案中的非线性误差,并在实际应用中得到验证。
This paper presents the error analysis and correction method for temperature measurement of a platinum thermistor with Unbalanced Voltmeter Bridge. On the basis of the principle of Least Square Method, several polynomials were given and had been tested by experiments. This method was proven to be simple and valuable.
