各液位開關(guān)優(yōu)缺點(diǎn)及技術(shù)指標(biāo) </p> <p> 浮球液位開關(guān) </p> <p> 優(yōu)點(diǎn)：浮球開關(guān)不含導(dǎo)致故障發(fā)生和波紋管、彈簧、密封等部件。而是采用直浮子驅(qū)動(dòng)開關(guān)內(nèi)部磁鐵，浮球開關(guān)的簡捷的杠桿使開關(guān)瞬間動(dòng)作。浮子懸臂角限位設(shè)計(jì)，防止浮子垂直。 </p> <p> 浮球液位開關(guān)是一種結(jié)構(gòu)簡單、使用方便、安全可靠的液位控制器。它比一般機(jī)械開關(guān)速度快、工作壽命長;與電子開關(guān)相比，它又有抗負(fù)載沖擊能力強(qiáng)的特點(diǎn),一只產(chǎn)品可以實(shí)現(xiàn)多點(diǎn)控制。易于維護(hù)。使用于造船、造紙、印刷、發(fā)電機(jī)設(shè)備、石油化工、食品工業(yè)、水處理、電工、染料工業(yè)、油壓機(jī)械等方面。 </p> <p> 缺點(diǎn)：浮球開關(guān)是簡單的被動(dòng)器件，并且不具有自檢查功能，因此建議對(duì)其進(jìn)行定期檢查與維護(hù)，山東導(dǎo)波雷達(dá)液位計(jì)供貨商。浮球或浮筒物位計(jì)是活動(dòng)部件，因此用在更濃或黏稠液體中時(shí)會(huì)被弄臟。測量精度較差，黏度<0.8mpa*s時(shí)不能工作。對(duì)容器內(nèi)壓力、密度、介電常數(shù)有要求、安裝需停產(chǎn)，山東導(dǎo)波雷達(dá)液位計(jì)供貨商、清罐、開孔、動(dòng)火，山東導(dǎo)波雷達(dá)液位計(jì)供貨商。雷達(dá)式液位計(jì)為非接觸式液位計(jì)，可測壓力容器的液位。山東導(dǎo)波雷達(dá)液位計(jì)供貨商</p><div

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原理設(shè)計(jì)生產(chǎn)的。帶有磁體的浮球（簡稱浮球）在被測介質(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，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> 雷達(dá)物位計(jì)已成為物位測量儀表市場上的主流產(chǎn)品，主要分為雷達(dá)物位計(jì)和導(dǎo)波雷達(dá)物位計(jì)。 </p> <p> 雷達(dá)物位計(jì)發(fā)射功率很低的極短的微波通過天線系統(tǒng)發(fā)射并接收。雷達(dá)波以光速運(yùn)行。運(yùn)行時(shí)間可以通過電子部件被轉(zhuǎn)換成物位信號(hào)。一種特殊的時(shí)間延伸方法可以確保極短時(shí)間內(nèi)穩(wěn)定和精確的測量。即使存在虛假反射的時(shí)候，較新的微處理技術(shù)和軟件也可以準(zhǔn)確地分析出物位回波。通過輸入容器尺寸，可以將上空距離值轉(zhuǎn)換成與物位成正比的信號(hào)。儀表可以空倉調(diào)試。在固體測量中的應(yīng)用可以使用K-頻段的高頻傳感器。由于信號(hào)的聚焦效果非常好，料倉內(nèi)的安裝物或倉壁的粘附物都不會(huì)影響測量。在形形色色的傳感器大軍中，液位計(jì)占有重要的地位，它是我們生產(chǎn)生活的安全保障。</p><div

界面：兩種互不相溶的物質(zhì)的界面位置。 </p> <p> 物位測量儀表 </p> <p> 1、測液位的儀表：玻璃管（板）式、稱重式、浮力式（浮筒、浮球、浮標(biāo)）、靜壓式（壓力、壓差）、電容式、電感式、電阻式、超聲波式、激光式、微波式等 </p> <p> 2、測量界面的儀表：浮力式、差壓式、電極式、超聲波式等 </p> <p> 3、測量料位的儀表：重錘探測式、音叉式、超聲波式、激光式、放射性式等雷達(dá)液位計(jì)記錄脈沖波經(jīng)歷的時(shí)間，電磁波的傳輸速度為常數(shù)，算出液面到雷達(dá)天線的距離，知道液面的液位。山東導(dǎo)波雷達(dá)液位計(jì)供貨商</p><p style="text-indent:25px">導(dǎo)波雷達(dá)液位計(jì)的基礎(chǔ)是電磁波的時(shí)域反射原理，微波脈沖不是通過空間傳播，而是通過金屬導(dǎo)波桿傳播；山東導(dǎo)波雷達(dá)液位計(jì)供貨商</p><p> 浮球液位計(jì) </p> <p> 1、工作原理 </p> <p> 浮球液位計(jì)結(jié)構(gòu)主要是基于浮力和靜磁場原理設(shè)計(jì)生產(chǎn)的。帶有磁體的浮球在被測介質(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，使串連入電路的元件（如定值電阻）的數(shù)量發(fā)生變化，進(jìn)而使儀表電路系統(tǒng)的電學(xué)量發(fā)生改變。也就是使磁性浮子位置的變化引起電學(xué)量的變化。通過測量電學(xué)量的變化來反映容器內(nèi)液位的情況。 </p> <p> 2、特點(diǎn)及適用場合 </p> <p> 2.1結(jié)構(gòu)簡單、使用方便 </p> <p> 2.2性能穩(wěn)定、使用壽命長、便于安裝維護(hù) 幾乎可以適用于各種工業(yè)自動(dòng)化過程控制中的液位測量和控制，可以運(yùn)用于石油加工、食品加工、化工、水處理、制藥、電力、造紙、冶金、船舶和鍋爐等領(lǐng)域中的液位測量、控制與檢測。山東導(dǎo)波雷達(dá)液位計(jì)供貨商</p></p><br /><p>文章來源地址:
