光电管防干扰问题的分析与对策

Phototube Anti-Interference Analysis and Countermeasures

光电管是各类检测器件中非常重要的器件,其通断状态容易受某些外来因素(非障碍物)如太阳光线、浓度较高的粉尘、塑料纸及一些易漂浮的物品等的干扰,这些非障碍物中的存在可能导致光电管的误开关,影响设备的自动运转,给工作带来一定的影响。因此如何避开或防止这些因素的干扰,找出可行性措施和对策,是保持设备正常运转非常关键的。从工作中的经验出发,对影响光电管误开关最常见的因素阳光、粉尘、漂浮物进行了分析,并提出消除这些干扰的相应对策,从而减少了工作中由于光电管的误开关而产生的失误。

photoelectric cell is a very important detect device,its state easily influenced by some external factors such as sunlight,high concentration of dust,polythene sheet and some easy floating objects,the interference and obstacles in the photoelectric tube may result of the switch and equipment to automatic operation of work brings certain effect.So how to avoid or prevent these factors,to find feasible measures and policy is important to maintain the equipment function properly crucial,the work experience on a photoelectric of the affected by the most common factor in the sun,dust,floater was analyzed and made out the interference of the corresponding countermeasures in order to reduce the mistake caused by the photoelectric wrong switch.
