</p> <p> 2、通過高密封、防泄漏等技術(shù)措施，磁翻板液位即使在低溫、高溫、高壓、強(qiáng)腐蝕等各種惡劣的環(huán)境下，也能安全可靠工作; </p> <p> 3、因?yàn)榇欧逡何挥?jì)的兼容性高，所以一直以來在工業(yè)生產(chǎn)中都得到了***的應(yīng)用，是槽、罐等容器液位測量中的理想之選。 </p><p> 光電式液位開關(guān)

</p> <p> 應(yīng)用范圍：適用于石油、化工、電力、輕工及醫(yī)藥等行業(yè)污水處理及各類常壓和承壓窗口內(nèi)介質(zhì)液位的測量，尤其對于地下貯槽、貯罐的液位測量為理想。可適用于高溫、高壓粘稠、臟污介質(zhì)、瀝青、含臘等油品及易燃、易爆、腐蝕性等介質(zhì)的液位的連續(xù)測量。 </p> <p> 使用限制：一般使用在低量程的介質(zhì)比較粘、比較臟的槽罐，污水池，大量程狹窄的罐子不適用，使用工況比較范圍比較窄。 </p> <p> 精度等級：1.5級（我國工業(yè)儀表等級分為0.1，0.2，0.5，1.0，1.5，2.5，5.0七個(gè)等級）1.0以下屬于高精度。 </p> <p> 優(yōu)點(diǎn)：能有效克服懸浮物、泡沫等形成的假液位； </p> <p>

工作原理：伺服液位計(jì)的測量是基于浮力平衡原理而設(shè)計(jì)的。固定在驅(qū)動(dòng)電機(jī)的內(nèi)磁鐵輪與經(jīng)過精密加匿報(bào)輪鼓（即外磁鐵輪）之間完成磁偶合。使得輪鼓和驅(qū)動(dòng)電機(jī)形成同步旋轉(zhuǎn)，而內(nèi)磁與輪鼓（外磁鐵輪）之間被外殼完全隔離，從而使得被測液體腔與與電氣部分完全隔離而滿足防爆要求，將測量鋼絲均勻整齊的排列在輪鼓上。浮子通過測量鋼絲被送到罐內(nèi)。當(dāng)罐內(nèi)液位（界面或比重）變化時(shí)，由于浮子的重量隨變化的液位而改變，浮子變化的重量使得輪鼓（外磁鐵輪）與內(nèi)磁鐵輪之間形成耦合差。將該信號送入微處理器進(jìn)行計(jì)算判斷后，給伺服電機(jī)發(fā)出控制指令，使得罐內(nèi)浮子始終隨液位高度的變化而變化。從而即可以通過測量輪鼓的旋轉(zhuǎn)角度，計(jì)算后得到液位的高度值。 </p> <p> 應(yīng)用范圍：石**業(yè)、化工行業(yè)、食品行業(yè) </p> <p> 使用限制：主要應(yīng)用在(無腐蝕性的液體）輕油品的高精度測量中。 </p> <p> 精度等級：士0.3mm/±1mm </p> <p> 優(yōu)點(diǎn)：位測精度正負(fù)1毫米；液體表面氣泡及乳化層不影響測量精度；罐底沉積物不影響測量精度；可選用各種罐型的測量；同時(shí)測量液位、界面、比重及罐內(nèi)溫度。 </p> <p> 缺點(diǎn)：接觸式液位計(jì)、售價(jià)較高；安裝調(diào)試比較麻煩。山東雷達(dá)液位計(jì)廠家直銷</p><p
