High speed continuous processing of flat products (plastic film, metal foil or paper) requires tension precision to enable no change in material properties.
Large width products lead to the choice of WAT+S solution, with one transducer at each end and the roll, and misalignment correction by design.
Sensible thin materials such as the multilayers components of Labels requires high tension precision to keep their optimal quality.
Up to 300 mm width, the WAT+N series should be strongly recommended. The cantilever compensation concept enables to fully forget about the exact position of thee product on the cantilever roll, but to get the perfect precision of the applied tension.
Larger width products rather lead to the choice of WAT+S solution.

Filament winding requires high precision in tension for ensuring the expected final properties. Then it leads that close loop control is mandatory for enabling such a precision in the process control.
WAT+N and WAT+F are the perfect force measurement feedback components in the close loop systems for fibers, filaments, and narrow ribbons, when WAT+S is the one to be used to enable precision tension control the undwinding process for wide width of woven composites.

Either for individual cable processing or for large creels of wires, the consistency of quality on the final product usually relies on the tension regulation all along the manufacturing process.
WAT+S is the usual best option for each individual wire or cable measurement (with an added pulley).
When the wire path is not fixed in space (alternate transverse running at the immediate bobbin output, for instance), WAT+N is then the very best solution.
