Because the spandex tension lfuctuates in the process of sewing for self-adhesive spandex, the quality of fabric is seriously affect-ed. Introduction was made to the importance of self-adhesive spandex. Based on the bridge working principle, this paper developed a resistance tension tester with the output of 0~5V standard signal. With demands of detection of weak signals for organzine tension, this paper designed the ampliifer circuit and the iflter circuit and tested by tiny signals. The results show that the tester is perfect in use.
