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(jìn)行檢測，處理并將之轉(zhuǎn)換為一個開關(guān)信號，達(dá)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。 </p><p> 玻璃板液位計 </p> <p> 工作原理：連通器原理，液位計兩頭接待測容器液面上下，保持壓力一致，液位計里的液面高度就近似容器內(nèi)液面高度。 </p> <p> 應(yīng)用范圍：它主要用于直接顯示各種罐、塔、槽、箱等容器內(nèi)介質(zhì)液位的高度。 </p> <p> 使用限制：容器中的介質(zhì)必須是與鋼、鋼紙及石墨壓環(huán)不起腐蝕作用的。 </p> <p> 精度等級：±1cm </p> <p> 優(yōu)點：讀數(shù)清晰、直觀、可靠；結(jié)構(gòu)簡單、維修方便；經(jīng)久耐用 </p> <p> 缺點：1.厘米顯示，精度差 </p> <p> 2.對介質(zhì)有要求，不能測量與鋼、鋼紙及石墨材質(zhì)不起腐蝕作用的介質(zhì) </p> <p> 3.大量程運輸不方便，常溫常壓下汽化的介質(zhì)測量誤差大或無法測量磁翻板液位計以浮子為感測元件，利用磁鋼驅(qū)動翻片指示，因此無需能源輔助;</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="山東雷達(dá)液位計廠家批發(fā),位計" src="https://tyunfile.71360.com/UploadFile/jszhck/637412295800469307/9602383.png"></div><p> <p> 磁致伸縮液位計優(yōu)點： </p> <p> 1、可靠性強：由于磁致伸縮液位計采用波導(dǎo)原理，無機(jī)械可動部分，故無摩擦，無磨損。整個變換器閉在不銹鋼管內(nèi)，和測量介質(zhì)非接觸，傳感器工作可靠，壽命長。 </p> <p> <span style="font-size:12px;">2、精度高：由于磁致伸縮液位計用波導(dǎo)脈沖工作，工作中通過測量起始脈沖和終止脈沖的時間來確定被測液位移量，因些測量精度高，分辨率優(yōu)于0.01%FS，這是用其它傳感器難以達(dá)到的精度。</span> </p> <p> 3、安全性好：磁致伸縮液位計的防爆性能高，本安防爆，使用安全，特別適合對化工原料和易燃液體的測量。測量時無需開啟罐蓋，避免人工測量所在的不安全性。 </p> <p> 4、磁致伸縮液位計易于安裝和維護(hù)簡單：磁致伸縮液位儀一般通過罐頂已有管口進(jìn)行安裝，特別適用于地下儲罐和已投運儲罐的安裝，并可在安裝過程中不影響正常生產(chǎn)。 </p> <p> 5、便于系統(tǒng)自動化工作：磁致伸縮液位計的二次儀表采用標(biāo)準(zhǔn)輸出信號，便于微機(jī)對信號進(jìn)行處理，容易實現(xiàn)聯(lián)網(wǎng)工作，提高整個測量系統(tǒng)的自動化程度。 </p> </p> <p> <br /> 雷達(dá)液位計記錄脈沖波經(jīng)歷的時間，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。雷達(dá)料位計廠家</p><p style="text-indent:25px">差壓式液位汁是利用容器內(nèi)液位改變時，由液柱產(chǎn)生的靜壓也相應(yīng)變化的原理而工作的；山東雷達(dá)液位計廠家批發(fā)</p><p> 導(dǎo)波雷達(dá)液位計 </p> <p> 1 工作原理 </p> <p> 導(dǎo)波雷達(dá)液位計的基礎(chǔ)是電磁波的時域反射原理，微波脈沖不是通過空間傳播，而是通過金屬導(dǎo)波桿傳播，當(dāng)遇到與液面的接觸面時，由于波導(dǎo)體在氣體和液體中的導(dǎo)電性能不同，使波導(dǎo)體的阻抗發(fā)生驟然變化，從而產(chǎn)生一個液位原始脈沖，同時在波導(dǎo)體頂部具有一個預(yù)先設(shè)定的阻抗，該阻抗產(chǎn)生一個可靠的基本脈沖，雷達(dá)液位計檢測到液面脈沖后與基本脈沖進(jìn)行比較，從而計算出液面高度。 </p> <p> 2、特點及適用場合 </p> <p> 2.1測量不受罐體形狀的影響 </p> <p> 2.2不受介電常數(shù)、溫度、壓力和密度的影響 </p> <p> 2.3不受物位表面波動、粉塵、蒸汽和泡沫的影響 </p> <p> 2.4測量長度可以靈活變更，無須標(biāo)定 </p> <p> 2.5測量結(jié)果具有高精度、可重復(fù)性、**辯率 </p> <p> 2.6 適用的壓力范圍高達(dá)40bar 導(dǎo)波雷達(dá)液位計應(yīng)用于水液儲罐、酸堿儲罐、漿料儲罐、固體顆粒、小型儲油罐。各類導(dǎo)電、非導(dǎo)電介質(zhì)、腐蝕性介質(zhì)。山東雷達(dá)液位計廠家批發(fā)</p></p><br /><p>文章來源地址:
