工作原理：浮筒液位計(jì)是根據(jù)阿基米德定律和磁耦合原理設(shè)計(jì)而成的液位測(cè)量儀表，儀表可用來測(cè)量液位、界位和密度，負(fù)責(zé)上下限報(bào)警信號(hào)輸出。**于測(cè)量壓力容器內(nèi)液位，同四個(gè)基本部分組成：浮筒、彈簧、磁鋼室和指示器。 </p> <p> 應(yīng)用范圍：用于石油、化工、冶金、電力、醫(yī)藥、食品、造紙等行業(yè)液體的測(cè)量與過程控制。 </p> <p> 使用限制：一般的液態(tài)介質(zhì)都是可以測(cè)量的，但局限于小量程，大量程的浮筒液位計(jì)運(yùn)輸、安裝非常不方便，其他的費(fèi)用非常高，所以特別大量程的現(xiàn)場(chǎng)不建議使用浮筒液位計(jì)，超過5M基本上就沒有人做了 </p> <p> 精度等級(jí)：±0.5%FS </p> <p> 優(yōu)點(diǎn)：測(cè)量精度高； </p> <p> 智能化：利用HART通訊協(xié)議的該儀表使用戶容易存取過程操作的信息； </p> <p> 高靈敏：能反應(yīng)過程的小變化： </p> <p> 扭力管采用優(yōu)化的熱處理工藝，具有優(yōu)良的溫度和時(shí)間穩(wěn)定性； </p> <p> 結(jié)構(gòu)堅(jiān)固，耐腐蝕 </p> <p> 應(yīng)用面廣，適用性強(qiáng)。 </p> <p> 缺點(diǎn)：安裝，運(yùn)輸不方便，如果液罐過高則不適用。上海80HZ調(diào)頻雷達(dá)料位計(jì)供貨廠高溫磁翻板液位計(jì)適合在高溫高壓的液體里面進(jìn)行測(cè)量的，液位介質(zhì)比較高溫度可達(dá)450度。</p><div style="width:100%;text-align:

液位開關(guān)，顧名思義，就是用來控制液位的開關(guān)。從形式上主要分為接觸式和非接觸式。非接觸式的如電容式液位開關(guān),接觸式的例如:浮球式液位開關(guān)、電極式液位開關(guān)、電子式液位開關(guān)。電容式液位開關(guān)也可以采用接觸式方法實(shí)現(xiàn)。 </p> <p> 液位開關(guān)種類及原理 </p> <p> 浮球液位開關(guān) </p> <p> 浮球液位開關(guān)結(jié)構(gòu)主要基于浮力和靜磁場(chǎng)原理設(shè)計(jì)生產(chǎn)的。帶有磁體的浮球（簡稱浮球）在被測(cè)介質(zhì)中的位置受浮力作用影響：液位的變化導(dǎo)致磁性浮子位置的變化。浮球中的磁體和傳感器（磁簧開關(guān)）作用，產(chǎn)生開關(guān)信號(hào)。 </p> <p> 音叉液位開關(guān) </p> <p> 音叉液位開關(guān)的工作原理是通過安裝在基座上的一對(duì)壓電晶體使音叉在一定共振頻率下振動(dòng)。當(dāng)音叉液位開關(guān)的音叉與被測(cè)介質(zhì)相接觸時(shí)，音叉的頻率和振幅將改變，音叉液位開關(guān)的這些變化由智能電路來進(jìn)行檢測(cè)，處理并將之轉(zhuǎn)換為一個(gè)開關(guān)信號(hào)，達(dá)到液位報(bào)警或控制的目的。為了讓音叉伸到罐內(nèi)，通常使用法蘭或者帶螺紋的工藝接頭將音叉開關(guān)安裝到罐體的側(cè)面或者頂部。 </p><p> 電磁式液位開關(guān) </p> <p> 優(yōu)點(diǎn)：電子式有過壓保護(hù)功能；電磁式漏電電流保護(hù)可到300MA、分?jǐn)喾秶嗉?jí)、應(yīng)用量大。 </p> <p> <span style="font-size:12px;">電子式液位開關(guān)</span> </p> <p>

<p> 射頻導(dǎo)納液位開關(guān) </p> <p> 優(yōu)點(diǎn)： </p> <p> 1.通用性強(qiáng)：可測(cè)量液位及料位，可滿足不同溫度、壓力、介質(zhì)的測(cè)量要求，并可應(yīng)用于腐蝕、沖擊等惡劣場(chǎng)合。 </p> <p> 2.防掛料：獨(dú)特的電路設(shè)計(jì)和傳感器結(jié)構(gòu)，使其測(cè)量可以不受傳感器掛料影響，無需定期清潔，避免誤測(cè)量。 </p> <p> 3.免維護(hù) ：測(cè)量過程無可動(dòng)部件，不存在機(jī)械部件損壞問題，無須維護(hù)。 </p> <p> 4.抗干擾：接觸式測(cè)量，抗干擾能力強(qiáng)，可克服蒸汽、泡沫及攪拌對(duì)測(cè)量的影響。 </p> <p> 5.準(zhǔn)確可靠：測(cè)量量多樣化，使測(cè)量更加準(zhǔn)確，澤良不受環(huán)境變化影響，穩(wěn)定性高，使用壽命長。 </p> <p> 6.適用范圍：化工、油田、水及污水處理、造紙、制藥、電廠、冶金、水泥、糧食等行業(yè)。

1、浮力式：根據(jù)浮球或浮標(biāo)隨液位的高低而產(chǎn)生上下位移或浸于液體中的浮筒隨液位變化而引起浮力變化的原理。 </p> <p> （1）恒浮力（鋼帶、碼帶） </p> <p> （2）變浮力（浮筒） </p> <p> 原理如圖，浮筒隨液位變化產(chǎn)生浮力，浮筒本身的重力與浮力產(chǎn)生不平衡力，經(jīng)杠桿2傳至扭力管3，而扭力管產(chǎn)生轉(zhuǎn)角變形由心軸4傳出，經(jīng)推板5傳到霍爾片6產(chǎn)生電勢(shì)可被檢測(cè)。 </p> <p> 2、差壓式液位計(jì) </p> <p> 原理：容器內(nèi)的液位改變時(shí)，液柱產(chǎn)生的靜壓也相應(yīng)的變化。 </p> <p> H=PB-PA/gρ </p> <p> 3、電容式物位計(jì) </p> <p> 如圖圓柱形電容器，由兩個(gè)相互絕緣的同軸圓柱極板內(nèi)電極和外電極組成，在兩筒之間充入電介質(zhì)時(shí)，液位和兩極板直接電容成正比。 </p> <p> 4、超聲波物位計(jì) </p> <p> 聲波在液體、氣體、固體內(nèi)傳播時(shí)有一定的速度，當(dāng)聲波穿越介質(zhì)時(shí)會(huì)被吸收而衰減，氣體吸收強(qiáng)，衰減比較大，固體吸收弱，衰減也小，聲波穿過不同密度介質(zhì)界面時(shí)會(huì)有反射，超聲波物位計(jì)就是根據(jù)聲波從發(fā)生到接收反射回波的時(shí)間間隔與物位成正比的原理來測(cè)量的。電磁超聲波液位計(jì)有一系列優(yōu)良特性,可以解決其它超聲波液位計(jì)不易應(yīng)用的問題,如臟污流、腐蝕流的測(cè)量。山西雷達(dá)液位計(jì)價(jià)格</p><p
