我院光电系郑兆翁教授研制成一台ED-1000系列涡流式羽飞探测仪.该仪器属非接触式精密测量仪.其主要功能是:可以广泛用于探测金属罐、管、板及旋成体的壁厚度和腐蚀、伤痕、沙眼、夹杂物、晶格损伤等,并允许在一定厚度隔绝层之外测量;能探测焊缝质量,测出焊接的不良程度;探测金属与探头的距离,在一定范围内精确度可达百分之一毫米.它适用于军工、石油、化工、机械、航空、航天、造船、矿业、地质、电子、建工等各行各业.
Professor Zheng Zhaoweng of our institute has developed a ED-1000 series eddy current feather detector, which is a non-contact precision measuring instrument whose main functions are as follows: It can be widely used to detect metal cans, tubes, plates and spin forming bodies Wall thickness and corrosion, scars, trachoma, inclusions, lattice damage, etc., and allows a certain thickness of the insulation layer outside the measurement; to detect the quality of the weld, to determine the welding of the poor; detection of metal and probe distance, in a certain Accuracy within the range of 1%. It is suitable for military, petroleum, chemical, mechanical, aviation, aerospace, shipbuilding, mining, geology, electronics, construction and other industries.
