All Dover transducers have rugged stainless steel and aluminum construction for reliability and corrosion resistance. Several of our transducer products are not listed in this site. So, if you don't see a transducer that fits your needs exactly, please call or e-mail us. We also manufacture custom transducers to fit almost any tension measurement application.
Model C Tension Transducer
The industry standard tension transducers (sometimes called 'load cells'). These units, which contain high-accuracy semi-conductor strain-gauge sensors, are installed in pairs on idler roller shaft ends. Each roll-shaft transducer assembly can be mounted in a preferred web path location on your dual-frame web machine. Five standard mounting styles available for every machine configuration.
NW Narrow Web Tension Transducer
The Narrow Web tension transducer, now available in 3 standard roll diameters, combines a bearing-mounted idler roll and two tension sensing elements in one package. The most convenient direct tension-sensing devices you'll find anywhere for tension measurement and control on presses and machines with cantilevered narrow web rolls. Perfect for tag and label machinery.
Tension Roll® Transducer
Users are delighted with the precision performance and robust reliability of the TR Tension Roll® transducer, a unique sensing device for accurately measuring process web tension in any substrate. DFE Tension Roll® transducers and dead-shaft idler rolls are combined in one integral unit.
STR Segmented Tension Roll Transducer
The Segmented Tension Roll transducer is a specialty idler roller that measures tension on multiple individual web strands in a slitting and rewind environment.
Ribbon Filament Transducer
The RFA Ribbon Filament Transducers are designed to measure tension in any moving ribbon, filament, or very narrow web. Ideal for wire, plastic, rubber, metal, glass, composite or other flexible substrate.
VNW Very Narrow Web Transducer
The VNW (Very Narrow Web) transducer is a compact tension sensing device for measuring process tension in narrow web (up to six inches wide), ribbon or filament. The VNW transducer combines the robust and versatile design of DFE's time-proven Model C shaft-end transducers with a choice of mounting styles and wheel options from the RFA -style cantilevered transducers.
LT - Low Tension Transducer
Strong, compact low tension transducers that convert filament or web tension into a D.C. voltage proportional to tension. Typically used in filament winding, fiber processing and materials' applications that require tension control at very low levels.
Model F Heavy Duty Transducer
For those measurement applications with a high load (heavy tension) on the substrate and idler rolls in the web path, the Model FH or FV are the tension sensing tools to use. The F transducer is DFE's current generation tension sensors, used in pairs, for mounting 'under pillow-block' on machines with the idler roll shaft ends mounted in pillow-block bearings.
*CE-marked DFE Transducers are certified to conform with CE Requirements when used as accessories intended for use with CE-marked DFE electronics products (amplifiers, indicators).
