RFA Ribbon Filament Tension Transducer / Load Cell

Patterned after the legendary Model C transducer, the Ribbon Filament Transducer’s cantilevered form factor is ideal for wire, plastic, rubber, metal, glass, composite and other flexible substrates. Three standard wheels are available – ribbon (1-4 inches wide), filament and an adapter wheel which functions as a hub for mounting custom wheels. Three mounting styles are available: Screw, Flange and Pillow-Block.

HOW IT WORKS
Tension is measured by high performance semiconductor strain gauges embedded on a dual cantilevered beam and connected in a full Wheatstone bridge configuration. As the ribbon or filament passes over a rotating wheel assembly coupled to the end of the transducer, the beam deflects slightly in response to tension. This produces a voltage signal proportional to tension. The RFA transducer mounts cantilevered on a machine frame and may be connected to an indicator or controller for display or automatic control of web tension.

For the measurement of web widths wider than 4 inches, see the Narrow Web Transducer.
