我厂研制成功的用发光二极管进行焊条偏心坐标显示的“TH-2型电焊条偏心检测仪”,通过在生产中实际使用,收到了比较满意的效果。特别适用于在粉尘多、振动大、温度高、生产速度快的焊条生产线上使用。目前在我国焊条厂中广泛使用流水线生产,生产率较高,一般达到15根/秒左右。这就要求焊条偏心指示器必须有在1/15秒内完成指示的能力。一般的电动指示仪表根本无法达到这么快的反应速度。然而,使用晶体管驱动的、响应时间小于10毫微秒的磷砷化镓发光二极管(LED)就
The “TH-2 Electrode Displacement Detector”, which has been successfully developed by our factory, uses LED for electrode eccentricity display. Through the actual use in production, it has received satisfactory results. Particularly suitable for dust, vibration, high temperature, the production speed of the electrode production line used. Currently widely used in China’s electrode assembly line production, high productivity, generally reach 15 / s or so. This requires that the electrode eccentricity indicator must have the ability to complete the indication within 1/15 seconds. General electric indicating instrument simply can not achieve such a fast response speed. However, the use of transistor-driven phosphorescent gallium arsenide light-emitting diodes (LEDs) with response times of less than 10 nanoseconds
