RFA - Ribbon Filament Transducers

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.


Tension Transducers Capabilities

  • Measure tension of any narrow ribbon or filament
  • Small, versatile and easy-to-install
  • Special wheels are available
  • Load Ratings from 10 - 150 lbs (45 - 665N) with wide operating range

Ideal for wire, plastic, rubber, metal, glass, composite or other flexible substrate. Three standard wheels available--one for ribbon (specify width), one for filament, or the adapter model for custom requirements. Three mounting styles available: "S" (standard), "FL" (flange), and "PB" (pillow block).

HOW IT WORKS

Tension is measured by high performance strain gages 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 to a machine frame and may be connected to an indicator or controller for display or automatic control of web tension.

Three standard wheels are available: one for ribbon, one for filament, and an adapter wheel for custom requirements. The three mounting styles available are single bolt, flange, and pillow block.
