HR-YKA系列浮球式液位控制器適用于石油、化工、紡織印染、環(huán)保、民用建筑等各種敞口或密閉容器內(nèi)各種介質(zhì)的單點或多點液位的控制和報警。儀表結(jié)構(gòu)簡單、安裝方便、價格低廉

結(jié)構(gòu)原理
    液位開關(guān)主要由浮球、導(dǎo)桿、干簧管開關(guān)和接線盒等組成。根據(jù)測量介質(zhì)的不同，接液材質(zhì)有不銹鋼、PP、PTFE等。隨著液位上下變化，導(dǎo)桿外的浮球沿導(dǎo)桿上下移動，當(dāng)接近干簧管開關(guān)時，通過磁性耦合，浮球內(nèi)的永久磁鋼吸合導(dǎo)桿內(nèi)的干簧管開關(guān)，發(fā)出開關(guān)通斷信號。常開簧片開關(guān)處于磁場中時接通，處于磁場外時呈斷開狀態(tài)。常閉簧片開關(guān)處于磁場中時斷開，處于磁場外時呈接通狀態(tài)。兩種簧片開關(guān)工作狀態(tài)如下圖所示：
