实现运输机运输自动化,其中一个重要问题是如何监视转载点是否有煤粉堵塞现象、皮带是否跑偏、皮带上有无物料;而这通常是通过各种动作原理与结构的传感器(3Ⅲ—乙,KC—乙,PKCΠ,KC—乙各型)以及与传感器相似的开关钮装置来实现的。 采用各种不同型式的传感器,会给维护带来困难,同时还要补充必要数量的备件与部件。应用接触式动作原理,会降低传感器的工作可靠性。采用无触点动作原理,并具有足够 One of the most important issues is how to monitor whether there is clogging of pulverized coal at the transfer point, whether the belt runs away from the conveyor belt, whether there is any material on the belt or not, and this is usually measured by various sensors and sensors of movement principle and structure (3Ⅲ-B, KC-B, PKCΠ, KC-B each type) and sensor similar to the switch button device to achieve. Using a variety of different types of sensors can make maintenance more difficult, while still adding the necessary number of spare parts and components. Application of contact action principle, will reduce the reliability of the sensor. Using non-contact action principle, and has enough
