Cantilevered Idler Roll with Dual Tension Sensors
Featured Product from Dover Flexo Electronics, Inc.
NW Narrow Web Tension Transducer
The NW Narrow Web Tension Transducer is a specialized bearing-mounted cantilevered idler roll with integrated dual tension sensors for measuring tension in a moving narrow web of paper, film, foil or other material.
Constructed of stainless steel and aluminum for excellent corrosion resistance, the NW transducer can be used as the sensing mechanism in a web tension control or display system in a continuous label, tag, or tape process. It mounts on a single-sided machine frame in the path with the cantilevered idler rolls.
Precision-balanced sensing elements fixed internally at each end of the idler roll deliver a highly accurate tension signal. 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 tighter.
The Narrow Web transducer is available in three roll diameters: NW size 0 is 2.25 inches (57 mm); NW size 1 is 3 inches (76 mm); and the NW size 2 is 3.5 inches (89 mm).
DFE is the natural choice of process and maintenance engineers for upgrading existing machinery with modern, efficient tension control. OEMs and machinery builders choose DFE to incorporate the most reliable, cost-effective tension controls into their machine designs. Consistent quality, product reliability and superior technical support translate into low cost of ownership for all our customers.
Are you measuring process tension on web or flexible substrate?

Our products are used in unwind, rewind, and intermediate applications for any moving continuous material which undergoes an operation such as printing, coating, laminating, treating, metallizing, rewinding, unwinding, slitting, coating or other processes. Tension measurement and control systems for flexible packaging and paper, film and foil converting are our specialty.
We have over 84,000 tension transducers installed in manufacturing facilities everywhere. DFE transducers (sometimes referred to as 'load cells') are the industry standard for direct tension sensing and measurement. We are a recognized leader in tension technology.
