| Abstract: | The relationship between input and output of pressure sensors is usually expressed through linear curve,but it is not a linear relationship. The least square method is used to simulate the nonlinearity of pressure sensors＇ input and output,and the methods for these uncertainty calculations and evaluations were derived to improve measure accuracy. |
