電極式液位開關(guān)控制器常見原理：電極式液位開關(guān)控制器是利用液體之導(dǎo)電性來偵測液位高低。桶槽內(nèi)裝的物質(zhì)一旦觸及極棒，便會導(dǎo)電因而檢出信號，紹興防爆音叉液位開關(guān)生產(chǎn)廠家。經(jīng)控制器的信號放大后，再輸出一接點(diǎn)信號，供使用者做液位的控制。電極式液位開關(guān)控制器產(chǎn)品特點(diǎn) 1、適用于控制任何導(dǎo)電液體之液面。（禁止使用于揮發(fā)性液體） 2、具有突波保護(hù)功能，可有效防止突波干擾 3、可做多點(diǎn)控制，控制位置可由使用者需要訂制 4、電極頭使用低交流電壓，可避免電解作用，紹興防爆音叉液位開關(guān)生產(chǎn)廠家，并可延長使用壽命 5，紹興防爆音叉液位開關(guān)生產(chǎn)廠家、具有兩只指示燈，可顯示供水及排水狀態(tài)電容式液位開關(guān)是采用偵測液位變化時(shí)所引起的微小電容量(通常為PF)差值變化。紹興防爆音叉液位開關(guān)生產(chǎn)廠家</p><div style="width:100%;text-align: center;"><img style="max-width:

style="text-indent:25px">音叉式液位開關(guān)是一種新型的液位開關(guān)。它是利用音叉振動的原理設(shè)計(jì)制作的。它是在音叉液位開關(guān)的感應(yīng)棒底座，透過壓電晶片驅(qū)動音叉棒，并且由另外一壓電晶片接受振動訊號，使振動訊號得以循環(huán)，并且使感應(yīng)棒產(chǎn)生共振。當(dāng)物料與感應(yīng)棒接觸時(shí)，振動訊號逐漸變小，直到停止共振時(shí)，控制電路會輸出電氣接點(diǎn)信號。由于感應(yīng)棒感度由前端向后座依次減弱的自然原理，所以當(dāng)桶槽內(nèi)物料與桶周圍向上堆積，觸及感應(yīng)棒底座〈后部〉或排料時(shí)，均不會產(chǎn)生錯誤訊號。簡單的說，音叉在壓電晶體激勵下產(chǎn)生機(jī)械振動，這種振動具有一定的頻率和振幅。當(dāng)音叉被液體或固體浸沒時(shí)，音叉的振動頻率和振幅將發(fā)生變化。這個(gè)頻率變化由電子線路檢測出來并輸出一個(gè)開關(guān)量。</p><p style="text-indent:25px">電極式液位傳感器原理電極式是早的液位控制方式，其控制原理很簡單：因?yàn)樗菍?dǎo)體，有水的時(shí)候兩個(gè)電極間導(dǎo)電，交流接觸器吸合。但是電極在水中會分解而且會吸附很多雜質(zhì)。如果不及時(shí)清理，電極就會失去作用，這是電極式液位傳感器固有的缺陷。電極式液位傳感器的制造非常簡單，有人將導(dǎo)線外皮撥開，插到水里就可以做成電極式液位控制器。所以電極式液位控制器造價(jià)很低，價(jià)格便宜，但使用壽命很短。當(dāng)然，如果采用不銹鋼做電極，硬度較強(qiáng)，分解得就會慢一點(diǎn)。如果表面再處理光滑一些,電鍍一下，吸附的雜質(zhì)就會少一些，使用壽命就會長一點(diǎn)。但是無論怎么做，其品質(zhì)都不可能超過干簧管。二、UQK液位控制原理干簧管將電極觸點(diǎn)密封在玻璃管內(nèi)，接近磁鐵，觸點(diǎn)就會吸合。所以人們在浮球里放一塊磁鐵和上、下兩個(gè)干簧管，通過導(dǎo)線將浮球固定于水池中，這就是UQK的液位控制方式。當(dāng)水池?zé)o水的時(shí)候，浮球下垂，磁鐵在下限干簧管處，故下限干簧管吸合。電子式液位開關(guān)工作電壓是DC5V-24V。</p><div
