Tension Transducers
|
|
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.
|
|
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® transducers and dead-shaft idler roll are combined
in one integral unit.
|
 |
The RFA Ribbon Filament Transducers are designed to measure tension
in any moving ribbon, filament, or very narrow web.
|
 |
These
transducers, used in pairs, quickly convert a simple metal tube into
a
tension-sensing idler roll.
|
|
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
|
 |
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.
|
 |
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. The model F transducer has taken the place of DFE's previous line of UPB-style 'Under Pillow-Block' transducers.
