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，河南導(dǎo)波雷達液位計批發(fā)采購、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)生電勢可被檢測。 </p> <p> 2、差壓式液位計 </p> <p> 原理：容器內(nèi)的液位改變時，液柱產(chǎn)生的靜壓也相應(yīng)的變化，河南導(dǎo)波雷達液位計批發(fā)采購。 </p> <p> H=PB-PA/gρ </p> <p> 3、電容式物位計 </p> <p> 如圖圓柱形電容器，由兩個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，液位和兩極板直接電容成正比。 </p> <p> 4、超聲波物位計 </p> <p> 聲波在液體、氣體、固體內(nèi)傳播時有一定的速度，當(dāng)聲波穿越介質(zhì)時會被吸收而衰減，氣體吸收強，衰減比較大，固體吸收弱，衰減也小，河南導(dǎo)波雷達液位計批發(fā)采購，聲波穿過不同密度介質(zhì)界面時會有反射，超聲波物位計就是根據(jù)聲波從發(fā)生到接收反射回波的時間間隔與物位成正比的原理來測量的。磁翻板液位計主要基于連通器和磁性耦合原理實現(xiàn)對液位的實時測量和顯示。河南導(dǎo)波雷達液位計批發(fā)采購</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南導(dǎo)波雷達液位計批發(fā)采購,位計" src="https://tyunfile.71360.com/UploadFile/jszhck/637412295730440801/26098.png"></div><p> 浮筒液位計 </p> <p> 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，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，但不適合高粘度介質(zhì)液位的測量。淮安雷達液位計廠雷達液位計采用非接觸式測量，不受槽內(nèi)液體的密度、濃度等物理特性的影響。</p><div

src="https://tyunfile.71360.com/UploadFile/jszhck/637412296201484967/888823.png"></div><p> 超聲波液位開關(guān) </p> <p> 超聲波液位開關(guān)內(nèi)部壓電晶體的叉形探頭中間被空氣隔開，一個晶體振動頻率為1.5MHz把聲音信號傳到空氣間隙中間，探頭浸入液體時，晶體，聲波偶合，超聲波液位開關(guān)改變狀態(tài)。 </p> <p> 技術(shù)指標(biāo)：比較大電纜長度：30m工作溫度：標(biāo)準(zhǔn)型:0~80℃中溫型：0~120℃環(huán)境溫度：-40~70℃工作壓力：常壓介質(zhì)密度：≥0.6g/cm觸點容量：220VAC </p> <p> 10A 電氣接口：M20*1.5防護等級：IP65過程連接：HG20592~20635-97 </p> <p>

優(yōu)點：振動音叉開關(guān)能真正地免受流量、氣泡、湍流、泡沫、振動、固體含量、沾敷、液體特性以及產(chǎn)品變化的影響。并且不需要校準(zhǔn)，只需要經(jīng)歷短的安裝過程便能完成安裝。無活動零件或縫隙真正實現(xiàn)免維護。強大的自檢查與診斷功能保證了高低物位測量的高可靠性，某些型號的物位計甚至可以在出現(xiàn)故障之前，繪出性能曲線和發(fā)送故障趨勢信號。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 缺點：音叉開關(guān)不適合用于非常粘的介質(zhì)。導(dǎo)致叉子被連接在一起的叉間物料堆積，將干擾物位檢測。 </p> <p> <br /> </p><p> 由于現(xiàn)場工況復(fù)雜，在實際測量中，要求有不同型號的磁翻板液位計與之相適應(yīng)。目前，磁翻板液位計按不同的標(biāo)準(zhǔn)可以分為不同的類型，如標(biāo)準(zhǔn)型、經(jīng)濟型、塑料型、內(nèi)襯型、防爆型、保溫型等等。上述不同類型的磁翻板液位計也具有各自不同的特點：（1）塑料型磁翻板液位計是常用的防腐型液位計，在相同的量程下，重量約只有標(biāo)準(zhǔn)型磁翻板液位計的1/5，特別方便現(xiàn)場的安裝。計為Flap-11C塑料型磁翻板液位計適用于電廠化學(xué)水處理、污水處理、印染行業(yè)，以及對PVC/PP不相溶的其他酸性介質(zhì)的測量。（2）計為Flap-11S經(jīng)濟型磁翻板液位計采用304不銹鋼材質(zhì)，適用于大部分工況與輕微腐蝕性液體的液位測量。經(jīng)濟適用是其為突出的特點，浮筒采用直徑51mm的**無縫不銹鋼管，有效避免了普通管材易泄漏、壽命短、耐壓不足等缺陷，提高了產(chǎn)品的可靠性。（3）Flap-11P內(nèi)襯四氟防腐型磁翻板液位計主要應(yīng)用于具有較強腐蝕性液體的測量，適用于強酸、強堿、強氧化劑、有機溶劑等介質(zhì)的測量，在化工、煉油、儲運和水處理等行業(yè)應(yīng)用。（4）計為防爆型磁翻板液位計適用于易燃易爆環(huán)境里，需要電信號遠程傳輸?shù)那闆r，與磁開關(guān)或遠傳變送器相配合，可以實現(xiàn)高低液位的報警動作和對液位實行遠程實時控制。雷達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)，算出液面到雷達天線的距離，知道液面的液位。</p><div

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：容器中的體質(zhì)必須是與鋼、鋼紙及石墨壓環(huán)不起腐蝕作用的液體。 </p> <p> 精度等級：±1cm </p> <p> 優(yōu)點：讀數(shù)清晰、直觀、可靠； </p> <p> 結(jié)構(gòu)簡單、維修方便； </p> <p> 經(jīng)久耐用。 </p> <p> 缺點：適用范圍較窄，易碎； </p> <p> 不堅固、不安全、不耐壓； </p> <p> 實用時間長或者測量介質(zhì)對刻度的磨損會顯示不清楚、使用溫度低； </p> <p> 大量程運輸不方便。磁翻板液位計與超聲波液位計比較大的區(qū)別就是接觸式測量和非接觸式測量。江西雷達液位計哪家好</p><p

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。 </p> <p> 應(yīng)用范圍：水泥、礦山、冶金、化學(xué)工業(yè)、塑料工業(yè)、建筑材料、食品工業(yè)。 </p> <p> 使用限制：精度很差，一般用在礦廠、石灰廠用來測量料位 </p> <p> 精度等級：測量誤差（mm）：±4.5；±1%FS、低 </p> <p> 優(yōu)點：具有實用性強、測量范圍大、精度高性能穩(wěn)定、使用壽命長、便于維護等,大型計數(shù)器顯示，使得讀數(shù)清晰準(zhǔn)確；手動浮子提升機構(gòu)，可隨時檢查儀表工作情況；可與多種變送器連接，組成液位檢測系統(tǒng). </p> <p> 缺點：精度差 </p> <p> <br /> 河南導(dǎo)波雷達液位計批發(fā)采購</p></p><br
