【Abstract】 Based on the principle of positive feedback,two new approaches to non linearity compensation for platinum resistor in temperature measurement are put forward,namely,the series expansion based approach and the minimum pseudo relative error based approach.Analytical expressions of optimal parameters are also given.It has been shown in practical applications that the methods proposed in this paper are not only correct,precise and practical,but also can make it convenient for platinum resistors to be applied in measurement and control systems.更多还原
