作為常見的物位儀表產(chǎn)品，按照微波的波形劃分，非接觸式雷達(dá)料位計分為脈沖雷達(dá)料位計和調(diào)頻連續(xù)波雷達(dá)料位計。而按照工作方式進行劃分，雷達(dá)料位計又分為接觸式雷達(dá)料位計和非接觸式雷達(dá)料位計。 </p> <p> 目前，雷達(dá)料位計在電力、鋼鐵、冶金、水泥、造紙、食品、石油化工等許多行業(yè)被用于對各種金屬、非金屬容器或管道內(nèi)的液體、漿料及顆粒料進行物位測量。即使在具有較多粉塵和溫度、壓力變化較大以及有惰性氣體及蒸汽存在的場合和復(fù)雜工況下，雷達(dá)料位計仍能可靠工作。 </p> <p> 由于雷達(dá)料位計非常便于現(xiàn)場工作人員的觀察，能夠?qū)崟r監(jiān)控指定儲罐內(nèi)物料的使用情況，因此常被用于工業(yè)生產(chǎn)的加工過程中。 </p><p> 雷達(dá)料位計的基本原理 </p> <p> 雷達(dá)式料位計組成：它主要由發(fā)射和接收裝置、信號處理器、天線、操作面板、顯示、故障報警等幾部分組成。 </p> <p> 發(fā)射－反射－接收是雷達(dá)式料位計工作的基本原理。雷達(dá)傳感器的天線以波束的形式發(fā)射**小5.8GHz的雷達(dá)信號。反射回來的信號仍由天線接收，雷達(dá)脈沖信號從發(fā)射到接收的運行時間與傳感器到介質(zhì)表面的距離以及物位成比例。即：h= H–vt/2 式中 h為料位；H為槽高；v為雷達(dá)波速度；t為雷達(dá)波發(fā)射到接收的間隔時間。雷達(dá)料位計是通過處理雷達(dá)波從探頭發(fā)射到介質(zhì)表面，然后返回到探頭的時間來測量料位的。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

盡量避免在發(fā)射角內(nèi)有造成假反射的裝置。特別要避免在距離天線近的1/3錐形發(fā)射區(qū)內(nèi)有障礙裝置（因為障礙裝置越近，虛假反射信號越強）。若實在避免不了，建議用一個折射板將過強的虛假反射信號折射走。這樣可以減小假回波的能量密度，使傳感器較容易地將虛假信號濾出。 </p> <p> 要避開進料口，以免產(chǎn)生虛假反射。 </p> <p> 傳感器不要安裝在拱形罐的中心處（否則傳感器收到的虛假回波會增強），也不能距離罐壁很近安裝，比較好安裝位置在容器半徑的1/2處。 </p> <p> 要避免安裝在有很強渦流的地方。如：由于攪拌或很強的化學(xué)反應(yīng)等，建議采用導(dǎo)波管或旁通管測量。 </p> <p> 若傳感器安裝在接管上，天線必須從接管伸出來。喇叭口天線伸出接管至少10mm。棒式天線接管長度比較大100或250mm。接管直徑小250mm?？梢圆扇〖哟蠼庸苤睆降姆椒ǎ詼p少由于接管產(chǎn)生的干擾回波。 </p> <p> 關(guān)于導(dǎo)波管天線：導(dǎo)波管內(nèi)壁一定要光滑，下面開口的導(dǎo)波管必須達(dá)到需要的比較低液位，這樣才能在管道中進行測量。傳感器的類型牌要對準(zhǔn)導(dǎo)波管開孔的軸線。若被測介電常數(shù)小于4，需在導(dǎo)波管末端安裝反射板，或?qū)?dǎo)波管末端彎成一個彎度，將容器底的反射回波折射走。非接觸式雷達(dá)料位計由于具有安裝簡單、維護量少、使用方式靈活、不受倉內(nèi)粉塵、溫度等因素影響等特點。泰州水滴型雷達(dá)料位計供貨商</p><p

安裝雷達(dá)物位計時要避免傳感器和罐壁的接觸，應(yīng)該和管壁保持一定距離。因為雷達(dá)物位計是通過發(fā)出高頻微波脈沖沿著探測組件傳播測量的，這些脈沖波遇到被測介質(zhì)介電常數(shù)就會發(fā)生變化，引起反射。因此，要是安裝的物位計離管壁過近就可能得到的是管壁的介電常數(shù)，直接導(dǎo)致了被測參數(shù)的不準(zhǔn)確。 </p> <p> 雷達(dá)物位計的正確安裝方法 </p> <p> 1、建議安裝短管的外壁距離罐體內(nèi)壁應(yīng)該大于罐體直徑的1/6； </p> <p> 2、安裝短管的外壁距離罐體內(nèi)壁的距離小不得低于300mm； </p> <p> 3、不能將雷達(dá)物位計安裝在入料口的上方； </p> <p> 4、不能安裝在罐體中心位置，如果安裝在**，會產(chǎn)生多重虛假回波，干擾回波會導(dǎo)致信號丟失。 </p> <p> 5、如果不能保持儀表與罐壁的距離，罐壁上的介質(zhì)會黏附造成虛假回波，在調(diào)試儀表的時候應(yīng)該進行虛假回波存儲。淮安水滴型雷達(dá)料位計哪里可以買</p></p><br /><p>文章來源地址:
