The NWI Narrow Web Tension Transducer is highly accurate because it has sensing elements at each end of the idler roll. This arrangement is functionally the same as wide web tension measuring schemes, using two tension transducers and a separate idler roll. The sensing elements measure total web tension accurately regardless of web position on the roll, and regardless of which edge of the web is tight. Constructed of stainless steel and aluminum for excellent corrosion resistance.

A new option of the Narrow Web tension transducer is a built-in, digital, LED tension display at the end of the roll. The base of the NWI roll bolts onto the cantilevered frame of a press or machine at a desired point in the web path and reads out running tension on the LED display during operation. For a machine operator, who must make control adjustments when web tension runs outside acceptable limits, the direct on-roll tension display is convenient and easy-to-read. The Narrow Web tension transducer is covered by DFE's Tension-Free 5-YEAR PRODUCT WARRANTY.
