Scan the Belt's Skid without Contact in Pan Steel's Blast Furnace

Double line approach switch can be used as a method of Scanning belt skid.These approach switches use 24 volt d.c.And choose the right diameter,Instead of Scanning the belt's skid with contact,and widely used in Pan steel's belt system.Design approach object,inspect method,process programme,ameliorate them in order to solve new problem,avoid wrong signals stop the belt.Ensure production is the first important,so avoid the damage by belt's skid with contact and the material's excessive accumulate,can ensure the material's supply,reduce the cost of producing and maintenance.
