Constant tension control principle
Release Date:07/01/2016
The working principle of automatic constant tension controller is actual goal tension(that is, measuring tension)measured by two tension detectors compare with the necessary working tension(that is, setting tension)set by manual, if this two compared tension is equal, tension controller does not adjust output ratio, or when this compared tension is not equal, the tension controller will judge the measure tension is greater or less than setting tension and correspondingly decrease or increase the output ratio, so that measuring tension and setting tension can maintain a dynamic balance to achieve constant tension.
