關(guān)于工業(yè)儀表的常見故障分析

通過對(duì)工業(yè)儀表儀器故障現(xiàn)象和它產(chǎn)生發(fā)展過程的調(diào)查了解,分析判斷故障原因的方法。一般有以下幾個(gè)方面: 

(1)在正常作用中出現(xiàn)的故障,還是在修理更換元器件后出現(xiàn)的故障; 

(2)有無受到外界強(qiáng)電場(chǎng)、磁場(chǎng)的干擾;

(3)過熱、雷電、潮濕、碰撞等外界情況;  

(4)供電電壓變化情況;  

(5)故障發(fā)生時(shí)有無打火、冒煙、異常氣味等現(xiàn)象;

(6)故障發(fā)生前的使用情況和有無什么先兆;

(7)是否有使用不當(dāng)或誤操作情況;
