现代检测系统以及诸如细导线、玻璃丝光纤、毛细管和单螺旋线这类产品的成型工艺过程控制系统的发展,由于测量准确度低、局部定域性不够和现有一次变换器速率不高而受到阻碍。分析表明,基于光电子法的交换器配合某些计算装置后,就会较其它的一次变换器具有更多的优点:可以进行不接触测量;对外 The development of modern inspection systems and molding process control systems for such products as fine wire, glass fiber, capillary and single helix has been hampered by poor measurement accuracy, inadequate local localization and low rate of existing primary converters Hinder Analysis shows that the optoelectronic-based switch with some computing devices, it will have more advantages than other converters: can make non-contact measurement; external
