【Abstract】 In light of the status quo and existing problems of level measurement in the pulverized coal bunker of coal-fired boiler,a new measurement theory that uses multiple segment capacitor,continuous perpendicular permutation and bus driving is presented in this paper.Based on the theory,an on-line monitoring system with high accuracy,high reliability and high cost performance for material level measurement is developed.The applications of this system in more than sixty thermal power plants have achieved good results,being appropriate to popularize in thermal power plants.更多还原
