SHANG Yu-pei ,SHI Lin-suo ,ZHANG Zhen-ren (Dept. of Mech. and Elec. Engi.,Second Artillery Engineering College , Xi'an 710025,China)  
WT5”BZ]The nonlinearity of sensor is improved with the hardware circuit when the A class industrial Pt100 temperature sensor is used to measure temperature, and on the basis of improving the nonlinearity a polynomials is given by the principle of least square method.A good result with the method in the viscosity designedh as been obtained by us.
