LESSON 50

总结确认“直径”、“深度”、“摆动”等测量相关单词

接掉了来，下面对话的例。

I'd like to check the outer diameter of the screw, but I wonder if the reflected light from the metal surface causes sensor malfunctions. Screws that have less than ten milimeter in diameter are not good and the tolerance should be within 0.2mm. Do you have any good ideas?: 我想在生产线上辨别螺丝的外径，但是担心金属面的反射光会使传感器发生误动作。直径10毫米以下的螺丝为NG，公差应该是0.2 mm，有没有好办法？

How about using a fiber sensor that has a 0.1mm diameter beam spot? You set the beam spot on the edge of the outer diameter of the screw, and then if the beam returns the screw is good but if the beam doesn't return the screw is not good. Even if the object has a metal surface, a thru-beam type sensor that has a narrow beam spot can detect the object properly.: 试着使用光点直径为0.1 mm的光纤传感器怎么样？将光点设在接近螺丝外径处，如果光线返回则OK，不返回则为判定为错误。即使测量目标是金属面，只要使用小光点的透过型传感器，就能稳定地检测到哦。
