Web Tension Transducer handles narrow webs or filaments.

Press Release Summary:



VNW Very Narrow Web tension transducer measures process tension in narrow web or ribbon (up to 6 in. wide) or filament. It can be installed on process machinery for unwind/payoff, rewind/take-up or intermediate zone applications. Tension is measured by high-output silicon strain gages housed internally on dual cantilevered transducer beam. Six different mounting styles are offered to accommodate space constraints and various machine frames.

Versatile VNW (Very Narrow Web) Tension Transducer


(ROCHESTER, NH, USA--November 27, 2001) The new VNW (Very Narrow Web) transducer from Dover Flexo Electronics (DFE) is a compact tension-sensing device for measuring process tension in narrow web or ribbon (up to six inches wide) or filament.

Employing a design that combines the robust beam housing of DFE's popular shaft-end transducers with a choice of mounting styles and wheel options from RFA-style cantilevered transducers, DFE has developed a versatile new cantilever-mount tension transducer. The functional advantage of the new VNW device over other cantilevered transducers is that the shaft insertion depth can be adjusted (+/- 0.25 inch) for easier alignment of the wheel with the web. The company offers the transducer for a highly competitive base price.

The VNW can be installed on process machinery for unwind/ payoff, rewind/ take-up, or intermediate zone applications. Tension is measured by high-output silicon strain gages housed internally on a dual cantilevered transducer beam. The transducer output signal is amplified by a DFE indicator or automatic controller for tension measurement or complete closed-loop tension control.

To accommodate space constraints and a variety of machine frame conditions six different mounting styles are offered. All ribbon and filament wheels are optional accessories. The wheels are shaft-mounted with the shaft inserted into the transducer's face coupling and secured by set screws. Pictured is the VNW transducer with piloted flange mount and 6-inch width ribbon wheel.
