Abstract: Because the spandex tension fluctuates in the process of sewing for self-adhesive spandex, the quality of fabric is seriously affected.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 0~5 V standard signal. With demands of detection of weak signals for organzine tension, this paper designed the amplifier circuit and the filter circuit and tested by tiny signals. The results show that the tester is perfect in use.
Key words: self-adhesive spandex; tension tester; filtering; signal; amplifying circuit
