油田磁浮子液位計根據(jù)浮力原理和磁性耦合作用研制而成。當被測容器中的液位升降時，液位計主導管中的浮子也隨之升降，浮子內(nèi)的*磁鋼通過磁耦合傳遞到現(xiàn)場指示器，驅動紅、白翻柱翻轉，當液位上升時，翻柱隨著液位的高度轉為紅色，當液位下降時，翻柱由紅色轉為白色。LB磁性位置變送器由液位傳感器和轉換模塊組成。改變送器的傳感器以捆綁的形式固定在UQC磁性浮球液位計的旁路管的外側，使其處于液位計同一磁場系統(tǒng)中，當磁性浮子隨液位上下移動時，對應液位位置的干簧管帶動電阻器轉換成二線制4~20mADC標準信號輸出AK型磁性報警開關采用日本進口的全密封磁保持開關及其他組件組成。該報警開關以嵌口的形式固定在UQC磁性浮球液位計標尺的外側，使其處于液位計同一磁場系統(tǒng)中，當磁性浮子隨液位上下移動時，對應液位位置的全密封保持開關作用吸合，輸出開關信號，陜西油庫液位計推薦，通過控制裝置達到控制目的。上述的位置變送器和報警開關輸出的信號可方便的與各類儀表配套使用，從而達到控制，陜西油庫液位計推薦，調(diào)節(jié)，陜西油庫液位計推薦，顯示及報警的目的。液位計投入運行時應先打開下引液管閥門讓液體介質平穩(wěn)進入主體管，避免液體介質帶著浮球組件急速上升。陜西油庫液位計推薦</p><div

style="text-indent:25px">什么是超聲波液位計的工作盲區(qū)?當物體離眼睛較近且角度一定的時候，反而看不清楚了或者看不見，在這一范圍就叫做盲區(qū)。超聲波液位計的盲區(qū)也如同人眼的盲區(qū)一樣。超聲波液位計的工作原理，是根據(jù)超聲波的發(fā)射和接收來實現(xiàn)的。超聲波在空氣中傳輸?shù)乃俣仁且欢ǖ?，超聲波發(fā)射出去，然后接收液面或物面反射回來的波，從發(fā)射開始計時，到接收到回波結束。超聲波在空氣中傳輸?shù)臅r間就定了。因為是一個來回，那實際距離就是距離的一半。池子的深度或罐體的高度是一定的。那實際液位就是池子的深度減去超聲波液位計測量的距離，就是液位或物位的高度了。由此，就實現(xiàn)了超聲波測量液位或者物位了。西安強腐蝕液位計推薦液位計常規(guī)檢查及故障解決方法,適用于磁翻板液位計，雙色石英管液位計，玻璃管液位計等。</p><div

1)在測量液體材料,軸的傳感器和表面的介質保持垂直;當測量固體材料,由于固體介質,會有一堆角傳感器傾斜一定的角度。(2)避免發(fā)射角是造成假反射裝置。特別要避免三分之一的錐形發(fā)射區(qū)靠近天線有屏障裝置(越接近設備,因為障礙虛假反射信號更強)。如果實在不能避免,建議使用一個假的反射折射董事會將會是一個強烈的信號折射。這樣我們可以減少虛假回波能量密度,傳感器很容易過濾掉錯誤的信號。(3)為了避免喂口,以免產(chǎn)生錯誤的反射。(4)傳感器不要安裝在鍋的中心拱(或反射回波的接收傳感器增強),也不能靠近罐壁安裝,zui好的安裝位置在1/2半徑的容器。 </p><p> 磁致伸縮液位計由電子倉內(nèi)電子電路產(chǎn)生一起始脈沖，此起始脈沖在波導絲中傳輸時，同時產(chǎn)生了一沿波導絲方向前進的旋轉磁場，當這個磁場與磁環(huán)或浮球中的長久磁場相遇時，產(chǎn)生磁致伸縮效應，使波導絲發(fā)生扭動，這一扭動被安裝在電子倉內(nèi)的拾能機構所感知并轉換成相應的電流脈沖，通過電子電路計算出兩個脈沖之間的時間差，即可精確測出被測的位移和液位。 </p> <p> 特點:具有精度高、穩(wěn)定性好、可靠性高、輸出信號多樣、使用壽命長、安全可靠等優(yōu)點。 </p> <p> 應用范圍：磁致伸縮液位計廣泛應用于工業(yè)過程控制、石油加工、制藥、食品加工、水處理、加油站、研磨機械、閥門開度控制等領域中的液位、溫度、密度、界面情況等物理參數(shù)的監(jiān)測、警報與控制。液位計主體周圍不容許有導磁體靠近否則直接影響液位計工F確工作。</p><div style="width:100%;text-align: center;"><img

帶有液位變送器的磁翻板液位計，應使用備用工具磁鋼吸引浮子室內(nèi)磁浮子運動，模擬液位變化，來檢測液位變送器工作是否正常。對于防爆型儀表不僅要檢測變送器的工作狀態(tài)參數(shù)，還要檢測器防爆性能。另外： </p> <p> a.液位計變送器和關聯(lián)設備之間的連接電纜為二芯屏蔽電纜，電纜芯線截面應不小于0.5mm。電纜的屏蔽層應在安全場所接地。 </p> <p> b.有防爆要求的儀表安裝時，維修必須在安全場所進行。在安裝和維修時必須切斷電源。在確認電源斷開后，再打開儀表接線盒。儀表的接線盒上的接地端子必須接有可靠的地線。在調(diào)整和使用的過程中，應注意保護儀表接線盒上的防爆螺紋接合面，不得有劃痕、碰撞等損傷。 </p> <p> c.儀表現(xiàn)場顯示部分投入運行后，接好電遠傳后，蓋上儀表接線盒，確認密封后通電。觀察數(shù)字顯示儀的液位值，如果電遠傳的液位值與現(xiàn)場顯示的液位值不一致時，可以松開喉箍，適當調(diào)整變送器的上下位置，直到達到一致。然后緊固喉箍。 </p> <p> d.帶有報警開關的液位計其報警開關為無源干接點開關。開關大體上可以分為常開、常閉、自保持等幾種，也可以根據(jù)用戶的需要，制作單刀雙擲開關。本液位計配套的液位計控制器主要用于控制小功率負載。不能用于直接控制大功率負載. 磁翻板液位計采用獨特的散熱方式，有效地控制了介儀表的工作溫度，避免了磁性元件在高溫條件下退磁。陜西油庫液位計推薦</p><p style="text-indent:25px">浮球液位計廣使用于煉油、化工、造紙、食品、及污水處理等行業(yè)。陜西油庫液位計推薦</p><p style="text-indent:25px">雷達液位計是雷達波嗎？雷達液位計是廣應用于：冶金冶煉，發(fā)電，水處理等行業(yè)，但是雷達物位計是雷達波嗎？下面我們將為您解釋一下這二者是什么關系，或者說他們之間有著何種特殊性，雷達波是一種特別方式地電磁波，而雷達液位計利用了電磁波地特別性能來施行料位檢驗測定，電磁波的物理特別的性質與可見光相仿，廣散布速度可以相當于光的速度。其頻率為300MHz-3000GHz。電磁波可以洞穿空間蒸汽、粉塵等干擾源，碰到絆腳石物還便于被反射，被勘測的媒介導電性越好或介電常數(shù)越大，回波信號地反射效果也會越好。陜西油庫液位計推薦</p></p><br
