1、根本型，根據(jù)浮力原理，浮子在丈量管內(nèi)隨液位的升降而上、下移動，浮子內(nèi)的持久磁鋼通過耦合效果，驅(qū)動紅、白色翻柱翻轉(zhuǎn)180°，液位上升時翻柱由白色轉(zhuǎn)為紅色，降低時由紅色轉(zhuǎn)為白色，然后完成液位指示。2、電遠(yuǎn)傳，在浮子液位計上裝置變送器，通過浮子上下移動，經(jīng)磁耦合效果使導(dǎo)桿內(nèi)丈量元件順次動作，取得電阻信號改變，轉(zhuǎn)換成0～10mA或4～20mA的標(biāo)準(zhǔn)信號輸出，與顯現(xiàn)外表或計算機(jī)連接，到達(dá)遠(yuǎn)傳意圖。 3、上下限開關(guān)輸出，在液位計立管上由用戶設(shè)定上、下限方位裝置操控器，操控器內(nèi)帶有自保持效果的舌簧開關(guān)，使用磁性浮子隨液位移動使簧片開關(guān)動作時，完成報警或限位操控，小型音叉液位控制器生產(chǎn)，小型音叉液位控制器生產(chǎn)。電纜浮球液位開關(guān)具有無毒，小型音叉液位控制器生產(chǎn)、耐腐蝕、安裝方便、使用壽命長等特點。小型音叉液位控制器生產(chǎn)</p><div

style="text-indent:25px">電纜浮球液位開關(guān)利用重力與浮力的原理設(shè)計而成，結(jié)構(gòu)簡單而合理，主要包括浮漂體，設(shè)置在浮漂體內(nèi)的大容量微型開關(guān)和能將開關(guān)處于通斷狀態(tài)的驅(qū)動機(jī)構(gòu)，以及與開關(guān)相連的三芯電纜。電纜浮球液位開關(guān)的特點是性能穩(wěn)定可靠（不因液面的波動而引起誤動作），同時，它還具有無毒、耐腐蝕、安裝方便、使用壽命長等特點。外測液位開關(guān)是一種利用“變頻超聲波技術(shù)”實現(xiàn)的非接觸式液位開關(guān)，經(jīng)常使用于各種液體的液體檢測。其測量探頭安裝在容器外壁上，屬于一種從罐外檢測液位的完全非接觸檢測儀表。儀表測量探頭發(fā)射超聲波，并檢測其在容器壁中的余振信號，當(dāng)液體漫過探頭時，此余振信號的幅值會變小，這個改變被儀表檢測到后輸出一個開關(guān)信號，達(dá)到液位報警的目的。</p><p style="text-indent:25px">電子式液位開關(guān)通過內(nèi)置電子探頭對水位進(jìn)行檢測，再由芯片對檢測到的信號進(jìn)行處理，當(dāng)判斷到有水時，芯片輸出高電平24V或5V等(PNP型或NPN型均可），當(dāng)判斷到無水時，芯片輸出0V。高低電平的信號通過PLC或其它控制電路來讀取，并驅(qū)動水泵等用電器工作。電子式液位開關(guān)可以橫向或豎向安裝。當(dāng)橫向安裝時，水位到達(dá)藍(lán)線就動作，且精度較高。豎向安裝時，水位到達(dá)紅線就動作，有一定的防波浪功能。電子式液位開關(guān)一般采用環(huán)氧樹脂封灌，密封防水，可長期浸在液體中，外部無機(jī)械活動部件，壽命長。普通型電子式液位開關(guān)，可以適用常溫水體環(huán)境。外貼式超聲波液位開關(guān)采用超聲波檢測技術(shù)，解決了傳統(tǒng)的液位開關(guān)的不足，不受液體表面的泡沫、水汽的影響。</p><div

style="text-indent:25px">音叉式液位開關(guān)工作原理：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，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(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，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，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。浮球液位開關(guān)是需要被安裝在水箱側(cè)面，從而來檢測液面的高低。小型音叉液位控制器生產(chǎn)</p><p style="text-indent:25px">液位開關(guān)有ON或OFF的接點信號輸出。小型音叉液位控制器生產(chǎn)</p><p style="text-indent:25px">液位開關(guān)安裝的時候主要看產(chǎn)品是屬于直裝式還是側(cè)裝式的，直裝式既可以頂裝也可以底裝，側(cè)裝式就是側(cè)面安裝，然后根據(jù)螺紋大小進(jìn)行固定安裝，一般是M10的或者是根據(jù)自己的運行環(huán)境來決定大小也都是可以的，安裝其實是很簡單的。電極式液位開關(guān)是利用液體的導(dǎo)電性來監(jiān)測液位的高低，解釋接觸到棒極，便會導(dǎo)電從而輸出報警信號。電極式液位開關(guān)可多點控制，控制位置由客戶需求而定，具有突破保護(hù)功能，可有效防止突波干擾，不過電極式液位開關(guān)*適用于導(dǎo)電液體。小型音叉液位控制器生產(chǎn)</p><p
