Chain-Code

     Check the chain code from a series of equal weight roller and its connection device, belt running, the roller in situ rotation on the belt, chain code can simulate the weight of the material on the weighing system of force, by calculating the corresponding theoretical weight And the belt scale shows the value compared to achieve the belt scale calibration. This calibration approach closer to the state of physical operation, combined with the use of Sai Mo belt scale material coefficient, can replace the physical check.
