導(dǎo)波雷達(dá)液位計(jì)與普通雷達(dá)液位計(jì)的比較普通雷達(dá)為非接觸式測量，導(dǎo)波雷達(dá)為接觸式測量，這樣就意味導(dǎo)波雷達(dá)更需考慮介質(zhì)的腐蝕性和粘附性，而且過長的導(dǎo)波雷達(dá)安裝和維護(hù)更加困難。普通雷達(dá)可以互換使用，而導(dǎo)波雷達(dá)由于導(dǎo)波桿（纜）長度根據(jù)原工況固定，一般不能互換使用，受此影響導(dǎo)波雷達(dá)的選型要比普通雷達(dá)麻煩。測量固體物料時(shí)，導(dǎo)波雷達(dá)還要考慮導(dǎo)波桿（纜）的受力情況，也是由于受力的原因一般用導(dǎo)波雷達(dá)的測量距離不會(huì)很長，而普通雷達(dá)在30、40m的罐體上應(yīng)用比較常見，甚至可測到60m。另外一般的導(dǎo)波雷達(dá)還有底部探測功能，可以根據(jù)底部回波信號(hào)能測量值加以修正，使信號(hào)更為穩(wěn)定準(zhǔn)確。不過在一些特殊工況導(dǎo)波雷達(dá)有明顯的優(yōu)勢，如罐內(nèi)有攪拌，介質(zhì)波動(dòng)大，這樣的工況用底部固定的導(dǎo)波雷達(dá)測量值要比變通雷達(dá)穩(wěn)定；還有小罐體內(nèi)的物位測量，由于安裝測量空間?。ɑ蚬迌?nèi)干擾物較多），一般普通雷達(dá)不適用，這時(shí)導(dǎo)波雷達(dá)的優(yōu)勢就顯現(xiàn)出來了；再有是低介電常數(shù)的工況，無論雷達(dá)還是導(dǎo)波雷達(dá)測量原理都是基于介質(zhì)介電常數(shù)差別，由于普通雷達(dá)的發(fā)射的波是發(fā)散的，當(dāng)介質(zhì)介電常數(shù)過低時(shí)，信號(hào)太弱測量不穩(wěn)定，而導(dǎo)波雷達(dá)波是沿導(dǎo)波桿傳播信號(hào)相對穩(wěn)定。宿遷高溫磁翻板液位計(jì)哪家比較好孔板式超聲波液位計(jì)結(jié)構(gòu)牢固,性能穩(wěn)定可靠,使用壽命長;</p><div

1、工作原理浮筒液位計(jì)由四個(gè)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(gè)力達(dá)到平衡時(shí)，浮筒就靜止在某一位置。當(dāng)液位發(fā)生變化時(shí)，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(dá)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(dòng)裝置使其指示出液位。 </p> <p> 2、特點(diǎn)及適用場合 </p> <p> 2.1現(xiàn)場指示、遠(yuǎn)傳兼容； </p> <p> 2.2測量范圍大，比較大可達(dá)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(qiáng)； </p> <p> 2.5現(xiàn)場調(diào)試方便，易于檢查和維護(hù)。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。 </p><p> 電磁超聲波液位計(jì) </p> <p>

目前常用液位檢測儀表有1、浮力式液位計(jì)原理:根據(jù)阿基米德原理工作，即液體對一個(gè)物體浮力的大小等于物體所排開液體的重量。類型:（1）恒浮力式液位計(jì)原理：在整個(gè)測量過程中其浮力維持不變，·在工作時(shí)浮標(biāo)隨液位面高、低而變化，如浮標(biāo)式、浮球式液位計(jì)、浮子鋼帶液位計(jì)等;其中浮球式液位計(jì)特別適用高溫、高粘度、小測暈范圍的液位測量。浮子鋼帶液位計(jì)則是用于大的球罐和柱罐的液位測量。（2）變浮力式液位計(jì)原理:它根據(jù)浮簡在液體內(nèi)浸沒的深度不同而所受浮力不同來測量液位，如浮筒式液位計(jì)，可用來測高溫、高壓介質(zhì)的液位。2、靜壓式液位計(jì)原理：對于不可壓縮的液體，液位高度與液體的靜壓力成正比，所以，測出液體的靜壓力，即可知道液位高度?！静顗鹤兯推?、單法蘭差壓變送器、雙法蘭差壓變送器、（可測壓力容器的液位，但不能用于高溫測量）投入式液位計(jì)（可測常壓容器的液位）】。3、電容式液位計(jì)原理：在平行板電容器之間充以不同介質(zhì)時(shí)，其電容量的大小是不同的?？梢杂脺y量容器的變化來檢測液位或兩種不同介質(zhì)的液位分界面。4、雷達(dá)式液位汁原理：利用超高頻電磁波經(jīng)天線向被測容器的液面發(fā)射，當(dāng)電磁波遇到液面后反射回來，通過測出發(fā)射波和反射波的時(shí)間差。磁翻板液位計(jì)主要基于連通器和磁性耦合原理實(shí)現(xiàn)對液位的實(shí)時(shí)測量和顯示。南京導(dǎo)波雷達(dá)液位計(jì)多少錢</p><p

電子式液位開關(guān)工作電壓是DC5V-24V，通過內(nèi)置電子探頭對水位進(jìn)行檢測，再由芯片對檢測到的信號(hào)進(jìn)行處理，當(dāng)被測液體的液位到達(dá)動(dòng)作點(diǎn)時(shí)，輸出DC5V-24V，可以直接與PLC配合使用或者與控制板配合使用，從而實(shí)現(xiàn)對液位的控制。 </p> <p> 光電式液位開關(guān) </p> <p> 光電液位開關(guān)使用紅外線探測，利用光線的折射及反射原理，光線在兩種不同介質(zhì)的分界面將產(chǎn)生反射或折射現(xiàn)象。當(dāng)被測液體處于高位時(shí)則被測液體與光電開關(guān)形成一種分界面，當(dāng)被測液體處于低位時(shí)，則空氣與光電開關(guān)形成另一種分界面，這兩種分界面使光電開關(guān)內(nèi)部光接收晶體所接收的的反射光強(qiáng)度不同，即對應(yīng)兩種不同的開關(guān)狀態(tài)。河北雷達(dá)液位計(jì)廠家直供</p><p
