磁敏雙色液位計(jì)為什么只顯示紅色呢?

    不亮的原因很有可能是里面的電子感應(yīng)元件故障所導(dǎo)致的只顯示紅色。磁磁敏雙色液位計(jì)是根據(jù)浮力原理和磁性耦合作用原理工作。當(dāng)被測(cè)容器中的液位升降時(shí),液位計(jì)主導(dǎo)管中的浮子也隨之升降,浮子內(nèi)的永久磁鋼通過(guò)磁耦合作用傳遞到現(xiàn)場(chǎng)顯示盒內(nèi)高精度電子感應(yīng)元件,觸發(fā)相應(yīng)的數(shù)字電路,使LED雙色發(fā)光管轉(zhuǎn)換顏色,無(wú)液全紅,滿(mǎn)液全綠,紅綠交界處就是容器內(nèi)的實(shí)際液位,從而實(shí)現(xiàn)液位的現(xiàn)場(chǎng)指示,氣紅液綠,一目了然;加裝限位開(kāi)關(guān)實(shí)現(xiàn)液位報(bào)警與控制,加裝變送器實(shí)現(xiàn)數(shù)字信號(hào)輸出供顯示與控制。
