style="text-indent:25px">射頻導納液位計：又名電容液位計，是不同廠家的不同叫法。基本原理：是利用電容器兩極板間的電介質(zhì)變化導致的電容變化來計算液體（也就是電介質(zhì)）的高度。當一個罐體確定、液位計裝好后，兩個極板的間距也就隨著確定了，那么電容值的主要影響因素就是電介質(zhì)（即被測液體），電介質(zhì)對電容的影響體現(xiàn)在本身的介電常數(shù)上，介電常數(shù)大的對應的電容值就高，介電常數(shù)小的對應的電容值就低。電容液位計能測量兩種不同介質(zhì)%的前提條件就是兩種介質(zhì)的介電常數(shù)有足夠大的差別，并且不互容，能夠出現(xiàn)明顯的分層。比如水（介電常數(shù)82）和油（介電常數(shù)一般在2左右）電容液位計要實現(xiàn)較為準確的測量必須進行現(xiàn)場實際標定，測單一介質(zhì)的時候空罐標零點，滿介質(zhì)標量程；用來測界面時要用介電常數(shù)低的介質(zhì)滿罐標零點，再用介電常數(shù)高的介質(zhì)滿罐標量程。</p><p 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計制作的。它是在音叉液位開關(guān)的感應棒底座，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)，并且使感應棒產(chǎn)生共振。當物料與感應棒接觸時，振動訊號逐漸變小，直到停止共振時，控制電路會輸出電氣接點信號。由于感應棒感度由前端向后座依次減弱的自然原理，所以當桶槽內(nèi)物料與桶周圍向上堆積，觸及感應棒底座〈后部〉或排料時，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)生機械振動，這種振動具有一定的頻率和振幅。當音叉被液體或固體浸沒時，音叉的振動頻率和振幅將發(fā)生變化。這個頻率變化由電子線路檢測出來并輸出一個開關(guān)量。振動音叉開關(guān)能真正地免受流量、氣泡、湍流、泡沫、振動、固體含量、沾敷、液體特性以及產(chǎn)品變化的影響。</p><div

style="text-indent:25px">射頻導納物位計分連續(xù)和點位（開關(guān)）兩種：在連續(xù)測量中，分單桿和雙桿(在大量程時多用單纜和雙纜），單桿用于外殼導電的（金屬等）設備，雙桿的（其中有一桿是參考電極）主要用于外壁絕緣（如地下水泥池，煤倉）的場合。測量桿又分帶絕緣層和不帶絕緣層的：帶絕緣層的用在導電介質(zhì)（如水）的場合，不帶絕緣層的用在絕緣介質(zhì)（如煤粉）的場合。輸出終為4-20MA電流信號。點位（開關(guān)量）輸出的，測量桿采用五層同心技術(shù)，中心桿，絕緣層，外面安裝螺紋，層層絕緣，克服掛料問題。輸出終為繼電器接點。液位測量是物位、壓力、流量、溫度、分析儀器五大類中的細分之一。徐州感應式液位開關(guān)批發(fā)</p><p
