1、工作原理浮筒液位計由四個基本部分組成：浮筒、彈簧、磁鋼室和指示器。浸在液體中的浮筒受到向下的重力，向上的浮力和彈簧彈力的復(fù)合作用。當(dāng)這三個力達到平衡時，浮筒就靜止在某一位置。當(dāng)液位發(fā)生變化時，浮筒所受浮力相應(yīng)改變，平衡狀態(tài)被打破，從而引起彈力變化即彈簧的伸縮，以達到新的平衡。彈簧的伸縮使其與剛性連接的磁鋼產(chǎn)生位移。這樣，徐州差壓式超聲波液位計哪家好，通過指示器內(nèi)磁感應(yīng)元件和傳動裝置使其指示出液位。 </p> <p> 2、特點及適用場合 </p> <p> 2.1現(xiàn)場指示、遠傳兼容； </p> <p> 2.2測量范圍大，比較大可達3000mm； </p> <p> 2.3工作可靠，良好的精度和靈敏度； </p> <p> 2.4耐高溫、高壓，耐腐蝕性能強； </p> <p> 2.5現(xiàn)場調(diào)試方便，易于檢查和維護。由于它直觀、穩(wěn)定、可靠性高、因而對連續(xù)生產(chǎn)的煉油、化工中的重要容器、設(shè)備，如塔類、貯罐中間容器等的液位測量都非常適用，徐州差壓式超聲波液位計哪家好，徐州差壓式超聲波液位計哪家好，但不適合高粘度介質(zhì)液位的測量。孔板式超聲波液位計結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長;徐州差壓式超聲波液位計哪家好</p><div

優(yōu)點：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)瞬間動作。浮子懸臂角限位設(shè)計，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，它又有抗負載沖擊能力強的特點,一只產(chǎn)品可以實現(xiàn)多點控制。易于維護。使用于造船、造紙、印刷、發(fā)電機設(shè)備、石油化工、食品工業(yè)、水處理、電工、染料工業(yè)、油壓機械等方面。 </p> <p> 缺點：浮球開關(guān)是簡單的被動器件，并且不具有自檢查功能，因此建議對其進行定期檢查與維護。浮球或浮筒物位計是活動部件，因此用在更濃或黏稠液體中時會被弄臟。測量精度較差，黏度<0.8mpa*s時不能工作。對容器內(nèi)壓力、密度、介電常數(shù)有要求、安裝需停產(chǎn)、清罐、開孔、動火。鹽城雷達料位計生產(chǎn)廠家雷達液位計的天線發(fā)射出電磁波，這些波經(jīng)被測對象表面反射后，再被天線接收；</p><div

工作原理：射頻導(dǎo)納物位控制技術(shù)是種從電容式物位控制技術(shù)發(fā)展起來的，防掛料性能更好，工作更可靠，測量更準確，適用更廣的物位控制技術(shù)“射頻導(dǎo)納”中的“導(dǎo)納”的含義為電學(xué)中阻抗的倒數(shù)，它由阻抗成份，容性成份，感性成份綜合而成，而“射頻”即高頻，所以射頻導(dǎo)納技術(shù)可以理解為用高頻電流測量導(dǎo)納的方法。高頻正鉉振蕩器輸出一個穩(wěn)定的測量信號源，利用電橋原理，以精確測量安裝在待測量容器聽傳感器上的導(dǎo)納，在直接作用模式下，儀表的輸出隨物位的升高而增加。 </p> <p> 使用范圍：適用于在高溫、高壓力、強腐蝕、強粘附、強沖擊、強磨損、粉塵大的環(huán)境下進行測量。高溫、高壓、易燃易爆，有毒，腐蝕等工況下，對液體，漿料，粉末，顆粒，塊狀物等物料，兩液體界面測量：如油水界面等。 </p> <p> 精度等級：±1%FS </p> <p> 優(yōu)點：適應(yīng)性強：采用和特殊抗沖擊、耐磨損探桿護套材料可在高溫、高壓力、強腐蝕、強粘附、強沖擊、強認捐、粉塵大的環(huán)境下可靠工作； </p> <p> 無需維護：由于傳感器結(jié)構(gòu)簡單，無可動部件，所以一經(jīng)投運后就無需維護； </p> <p> 無漂移：不會因為介質(zhì)的溫度或密度變化產(chǎn)生漂移。 </p><p> 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。 </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壓電晶體使音叉在一定共振頻率下振動。當(dāng)音叉液位開關(guān)的音叉與被測介質(zhì)相接觸時，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行檢測，處理并將之轉(zhuǎn)換為一個開關(guān)信號，達到液位報警或控制的目的。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。當(dāng)介質(zhì)內(nèi)出現(xiàn)真空啊、蒸汽含量過高、以及液面泡沫等情況時是不能選用超聲波液位計的；</p><div

工作原理：重錘液位計是一種傳統(tǒng)的液位計。它是利用力學(xué)平衡原理設(shè)計制作的。它是由料位檢測裝置、高精度位移傳動系統(tǒng)、恒力裝置、顯示裝置、變送器裝置以及其他外設(shè)構(gòu)成。當(dāng)被測物上升時探頭發(fā)出卷鋼信號，電機工作工作上卷。當(dāng)被測物不上升時，探頭給電機發(fā)出停止命令。當(dāng)被測物下降時垂錘探頭給電機了出反轉(zhuǎn)放鋼線命令，同時在上下限設(shè)定處報警，同時傳出4－20ＭＡ信號。液位檢測裝置根據(jù)物位的情況帶動鋼帶移動，位移傳動系統(tǒng)通過鋼帶的移動策動傳動銷轉(zhuǎn)動，進而作用于計數(shù)器來顯示液位的情況。
