Beschreibung
Zusammenfassung:	An apparatus and method for determining a tension in a target strand (11) , e.g. a yarn is disclosed. The method and apparatus provides a non-contact way for determining tension in any type of elongate element simply and efficiently by means of an optical ssensing head (14), e.g. of the CD linear array type. L'invention concerne un appareil et un procédé pour déterminer la tension dans un fil cible. Le procédé et l'appareil de l'invention utilisent une manière simple et efficace, ne nécessitant pas de contact, pour déterminer la tension dans un type d'élément allongé.
