| Abstract: | Based on the principle of positive feedback, two new approaches to non-linearity compensation for platinum resistor in temperature measurement, which are called the series expansion - based approach and the minimum pseudo relative error-based approach respectively,are put forward, and analytical expressions of optimal parameters are also given in this paper. It has been shown in practical applications that the methods proposed in the paper not only are correct, practical and precise, but also make it convenient for platinum resistor to be applied to measurement and control systerns. |
