摘要
本文根据纺织纤维的含水率对其相对介电常数的影响关系,提出一种纺织纤维含水率快速测量电路的设计方法,利用将电容传感器信号转换成电压信号的集成芯片CAV424构成信号的处理电路,通过A/D采样和单片机处理测出物料中的含水量;测试结果表明,该仪器可替代传统测湿方法,用以更新我国纺织企业的纤维水分测试技术。
The paper discusses a new instrument design method about quickly measuring moisture ratio in textile fibre based on the relation of moisture ratio and its relatively dielectric medium constant. Introduces the integrate circuit CAV424 used for capacitance to voltage signal convert; the test-resuh shows that the instrument can substitute traditional methods to improve fibre moisture testing technique in textile industries in our country.
