More in line with the law of network formation and maintain good flexibility in planning more scientific and ? 、感器故障判断 1、 故障机理 ? 从传感器的结构,感温头和传感线的密封性非常重要,外界微小的水分入侵即会造成参数的变化,因此感温头一般都做了三层密封处理,一是感温元件与焊点涂装防水绝缘材料,二层硅树脂或其他材料,三层封装头树脂帽内灌环氧树脂或玻璃封装,确保密封效果,并且对引线的材料有较高要求,必须采用耐寒线材,低温性能良好。 ? 传感线使用耐寒线,在低温下长时间冷热循环环境下不产生裂纹,如产生裂纹水分即会沿导线渗入感温元件引起参数变化。 ? 传感器感温元件焊点断裂变形 ? 传感线中间断、接触不良 ? 插接件接触不良 2、故障表现:传感器在正常工作时一般很少发生故障,是低故障率元件,除非在安装工艺和操作未按规定要求处理、使用前感温头受剧烈撞击,引线或感温头密封有裂纹产生、超高温超高电压使其内部元件损坏。但发生故障时通过主控板的检测会进行故障提示,显示报警状态或显示F1到F5 F1----冷藏蒸发器传感器短路或断路 F2----环境 传感器短路或断 路 F3----冷藏空间传感器短路或断路 F4----冷冻传感器短路或断路 F5----负7度传感器短路或断路 leading role, strengthening the capacity of regional radiation.
