Tension Controllers are designed to maintain constant tension throughout a vast range of applications and process speeds. The system includes a mini belt wrap capstan, a tension transducer, an AC Drive, AC Motor, and a self-tuning closed-loop Digital PID control system. The Controller provides user access to set the desired tension and displays the actual running tension of the wire. The tension transducer measures the actual running tension of the wire or cable while the controller adjusts the AC motor in order to achieve desire tensions. The progressive multi-stage dampening system reduces tension spikes without inducing secondary oscillations to the wire exiting the capstan wheel. These features all contribute to the elimination of the tension variation due to whipping fluctuations common to dual flyer payoffs.
