Measurement of yarn tension and its on-line monitoring

Abstract

Yarn tension in winding zone of dref-III machine has been measured by interfacing the Rothschild tensiometer with computer. A software in Qbasic has been developed for on-line measurement of yarn tension. The yarn tension variation during yarn forming in dref-III friction spinning by placing the sensor at the appropriate place has also been evaluated. It is observed that in certain zone where the tension variation is very high, it is convenient to use the software by changing the resolution of AD card. The average tension increases with the increase in spinning drum speed and the on-line graphical representation of the same can be obtained by computer programming using the Qbasic language.
