1.電容式料位計原理是插入料倉的電極與料倉壁之間構(gòu)成電容器，當(dāng)倉內(nèi)物料料位變化引起電容量的變化，通過轉(zhuǎn)換電路得到相應(yīng)的控制信號。 </p> <p> 優(yōu)點：無機械磨損，安裝維修方便；依據(jù)量程大小和控制方式不同，電極設(shè)計成桿（棒）式或鋼纜（重型鋼纜）式，可應(yīng)用于各種料倉；價格較低。 </p> <p> 缺點：若電極（探頭）上或倉壁粘有物料，往往會導(dǎo)致控制器誤動作，從而影響測量效果，應(yīng)定期檢查探頭和料位開關(guān)動作情況并校驗。 <p> 2.阻旋式料位計基本原理是同步微電動機減速后，帶動檢測葉片以2.5～5r/min的轉(zhuǎn)速旋轉(zhuǎn)，當(dāng)被測物料的料位上升使葉片轉(zhuǎn)動受阻，檢測機構(gòu)便圍繞主軸產(chǎn)生旋轉(zhuǎn)位移。該位移首先使一個微動開關(guān)動作，發(fā)出有料位信號，遼寧鐵礦石料倉料位計制造商。隨后另一個微動開關(guān)動作，切斷電動機電源使其停轉(zhuǎn)。 </p> <p> 優(yōu)點：開關(guān)結(jié)構(gòu)簡單，遼寧鐵礦石料倉料位計制造商，遼寧鐵礦石料倉料位計制造商、維護(hù)方便；價格較低。 </p> <p> 缺點：不適合在高溫下工作。 </p> 料位計是指對容器中固體物料高度的變化進(jìn)行實時檢測的儀表。遼寧鐵礦石料倉料位計制造商</p><div style="width:100%;text-align:

煤粉雷達(dá)料位計概述及原理： </p> <p> 高頻微波脈沖通過天線系統(tǒng)發(fā)射并接收，雷達(dá)波以光速運行，遇到被測介質(zhì)表面，其部分能量被反射回來，被同天線接收，發(fā)射脈沖與接收的脈沖的時間間隔與天線到被測介質(zhì)表面的離是成正比的，運行時間可以通過電子部件轉(zhuǎn)換成物位信號。一種特殊的時間延伸方法可以確保穩(wěn)定和精確的測量。即使工況比較復(fù)雜的情況下，存在回波用新的微處理技術(shù)和調(diào)試軟件也可以準(zhǔn)確的識別出物位的回波。
