Tension Electronics PFEA113, User Manual Section 3.12.6 Set Wrap Gain 3BSE029382R0101 Rev C 3-23 3.12.6 Set Wrap Gain To be able to present actual web tension on the display, the ratio between web tension and measured force on the load cell must be determined. This ratio is a scaling factor called Wrap Gain. The Wrap Gain depends on the web's wrap angle on the measuring roll and the orientation of the load cells. Therefore, Wrap Gain depends on the actual installation. This gives: T (tension) = Wrap Gain FR (force of web tension in load cell measuring direction) There are two ways to find out the ratio between web tension and measured force on the load cells, by Hanging weights or by Calculation. • With hanging weights (Menu HangWeight) String a rope that follows the web path exactly and apply a known weight. The applied known weight simulates the actual web tension and the electronics measures the resulting force on the load cells caused by the applied weight. When both web tension (T) and the corresponding measure f installation) Load
