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(dòng)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(dòng)音叉棒，并且由另外一壓電晶片接受振動(dòng)訊號(hào)，使振動(dòng)訊號(hào)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(dòng)訊號(hào)逐漸變小，直到停止共振時(shí)，控制電路會(huì)輸出電氣接點(diǎn)信號(hào)。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(huì)產(chǎn)生錯(cuò)誤訊號(hào)。簡(jiǎn)單的說，音叉在壓電晶體激勵(lì)下產(chǎn)生機(jī)械振動(dòng)，這種振動(dòng)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(dòng)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(cè)出來并輸出一個(gè)開關(guān)量。</p><p style="text-indent:25px">電容式液位開關(guān)是依據(jù)電容感應(yīng)原理，當(dāng)被測(cè)介質(zhì)浸汲測(cè)量電極的高度變化時(shí)，引起其電容變化。它可將各種物位、液位介質(zhì)高度的變化轉(zhuǎn)換成標(biāo)準(zhǔn)電流信號(hào)，遠(yuǎn)傳至操作控制室供二次儀表或計(jì)算機(jī)裝置進(jìn)行集中顯示、報(bào)警或自動(dòng)控制。（1）在使用過程中，如果儀表無(wú)電流輸出，應(yīng)檢查信號(hào)處理器“+”，“-”引出線是否松動(dòng)，脫落，儀表指示表頭固定螺紋及固定柱是否松有動(dòng)，接觸不良。如果出現(xiàn)以上的問題應(yīng)該立即進(jìn)行加固。（2）如果儀表指示為零，用手握金屬工具，如鑷子、螺絲刀等，接觸信號(hào)處理器“傳感器”端子，儀表指示應(yīng)增大，否則表明儀表信號(hào)處理器損壞。此時(shí)要進(jìn)行儀表信號(hào)處理器的更換。（3）如果儀表指示打滿，將信號(hào)處理器“傳感器”引線取下，若儀表指示燈依然打滿，表明信號(hào)處理器損壞，若儀表指示回零，則可能是傳感器絕緣不良。絕緣不好時(shí)應(yīng)該立即更換傳感器。（4）檢查傳感器方法：將傳感器引出線從信號(hào)處理器取下。用500V搖表或500型萬(wàn)用表“x10k”檔測(cè)量傳感器引出線與金屬塔壁間電阻，應(yīng)大于10M歐，否則表明傳感器絕緣不良。液位開關(guān)有ON或OFF的接點(diǎn)信號(hào)輸出。</p><div

1、電容式液位開關(guān)，電容式液位開關(guān)是選用偵測(cè)液位改變時(shí)所導(dǎo)致的細(xì)小電容量(一般為PF)差值改變，并由**的ADA電容檢查芯片進(jìn)行信號(hào)處理(能夠輸出多種信號(hào)通訊協(xié)議，如：IO,BCD, PWM,UART,IIC＆#823;)，然后檢查出水位，并輸出信號(hào)到輸出端。2、浮球式液位開關(guān)，浮球式液位開關(guān)的特點(diǎn)是有一個(gè)帶桿的浮球，跟著液位的改變，浮球聯(lián)動(dòng)的桿跟著改變，然后操控開關(guān)的閉合。工業(yè)上很早就使用浮子丈量水塔中的水位了。浮球液位開關(guān)分為模擬輸出型和開關(guān)量輸出型兩種。模擬量輸出型：磁性浮球隨液位的改變不斷觸發(fā)檢查桿中的磁簧開關(guān),使得傳感器的總電阻發(fā)生改變，該信號(hào)被變送器轉(zhuǎn)換成標(biāo)準(zhǔn)4＆#82320;mA信號(hào)輸出。開關(guān)量量輸出型：液位上升或降低時(shí)，股動(dòng)不銹鋼磁性浮球上下移動(dòng),浮球觸發(fā)檢查桿中的的磁簧開關(guān)，宣布信號(hào)。3、電磁式液位開關(guān)，開關(guān)量輸出型。液位上升或降低時(shí)，股動(dòng)不銹鋼磁性浮球(浮塊)上下移動(dòng)，至報(bào)警方位及時(shí)報(bào)警輸出。并可選溫度開關(guān)量輸出。浮球液位開關(guān)是利用微動(dòng)開關(guān)做接點(diǎn)輸出。自動(dòng)液位控制器購(gòu)買</p><p

style="text-indent:25px">液位開關(guān)安裝的時(shí)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(yùn)行環(huán)境來決定大小也都是可以的，安裝其實(shí)是很簡(jiǎn)單的。電極式液位開關(guān)是利用液體的導(dǎo)電性來監(jiān)測(cè)液位的高低，解釋接觸到棒極，便會(huì)導(dǎo)電從而輸出報(bào)警信號(hào)。電極式液位開關(guān)可多點(diǎn)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。自動(dòng)液位控制器購(gòu)買</p><p
