【Abstract】 In this paper a method of solving the problem in which there are more temperature measuring parameters than the regulators can deal with are presented. The curreut powred regulating circuit and the bridge regulating circuit are introducted. By making a comparison between the two we conclude that the structure of bridge regulating circuit is simpler but the current powred circuit has considerable strong point on which the influence of the resistance of the conducting wire of the function is eliminated.更多还原
