Abstract	K thermocouple which acts as energy converters is widely used in the process of industrial control and data acquisition. It can achieve the conversion between temperature signals and output voltages. The static characteristics of calibration should be carried out and analyzed based on the nonlinear relations between sensor's input and output. According to the principle of least squares fit, the system adopts a straight-line approach to linear. This paper introduces a polynomial fitting design scheme which can achieve dynamic connection of the electromotive force and temperature variation. This design makes use of n-polynomial approximation to nonlinear curve, whose coefficients are determined by the least squares polynomial equation, and conveys the corresponding algorithm value to the function of polynomial fit. his electronic document is a “live” template.
