摘 要: 自粘性弹力布在缝编生产过程中由于氨纶丝张力的波动,严重影响织物的质量。介绍了自粘性弹力布张力测试仪的重要性,基于电桥工作原理研发了输出为0 ~ 5 V 标准信号的电阻应变式张力测试仪。针对经丝张力微弱信号的检测要求,设计了信号放大电路和滤波电路,并进行实际测试。结果表明该测试仪取得了良好的使用效果。

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
