ROCHESTER, NH | Dover Flexo Electronics (DFE) used an animated simulation demonstration to launch the EasyWeb open loop torque controller at CPP EXPO, co-located with PRINT 13. This unit has now joined the company’s line of tension controllers as a lower-cost alternative to the highly precise transducer-based tension controllers for applications that may require less precision.
Unlike company’s tension controllers that take an input signal from tension transducers (load cells), web tension with the new model is maintained by controlling motor or brake torque based on the calculated variation of roll diameter as a roll is wound or unwound. An inertia compensation parameter is provided to obtain greater control of web tension during changes in line speed.
The torque controller can accept input signals from a direct diameter sensor or can calculate diameter using line and roll speed signals.
The simple user interface employs a bright OLED display said to offer easy viewing in any lighting conditions and at steep viewing angles. A large front dial allows fast, easy scrolling and selections through the user menu.
