</p> <p> 雷達物位計通過天線發(fā)射極窄且能量很低的微波脈沖信號，這個脈沖信號以光速在空間傳輸，遇到被測介質(zhì)發(fā)生反射，甘肅雙攬式雷達料位計推薦，反射信號被儀表接收，發(fā)射脈沖信號與接收脈沖信號的時間間隔與基準面到被測介質(zhì)表面的距離成正比，通過測量發(fā)射與接收的時間間隔，來實現(xiàn)天線至介質(zhì)表面距離的測量。 </p> <p> ①時間1：產(chǎn)生初始脈沖；②時間2：沿喇叭天線向下行進，速度C（光速）；③時間3：脈沖遇到介質(zhì)表面發(fā)生反射；④時間4：反射脈沖被接收，并被處理器記錄；⑤脈沖信號從被發(fā)射到被接收之間的時間差T，與基準面到介質(zhì)表面的距離D成正比：D=C×T/2；⑥測量的基準面是：螺紋底面或法蘭的密封面；⑦ A:量程 B:低位 C:滿位 D:盲區(qū)；⑧運行時，保證zui高料位不能進入測量盲區(qū)D。超聲波料位計適合于測量粒度較大的塊料料位。甘肅雙攬式雷達料位計推薦</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="甘肅雙攬式雷達料位計推薦,料位計"

style="text-indent:25px">阻旋式料位計：阻旋式料位計是一種料位開關(guān)。它也有不同的檢測控制方式，如某產(chǎn)品的基本原理是同步微電動機經(jīng)減速后，帶動檢測葉片以2.5～5r/min的轉(zhuǎn)速旋轉(zhuǎn)，當被測物料的料位上升使葉片的轉(zhuǎn)動受到阻礙時，檢測機構(gòu)便圍繞主軸產(chǎn)生旋轉(zhuǎn)位移。此位移首先使一個微動開關(guān)動作，發(fā)出有料位信號。隨后另一個微動開關(guān)動作，切斷電動機電源使其停轉(zhuǎn)。只要此料位不變這種狀態(tài)便一直保持下去。當料位下降至葉片失去阻擋時，檢測機構(gòu)便依靠彈簧拉力使其恢復原始狀態(tài)。一個微動開關(guān)先動作，接通電動機電源使其旋轉(zhuǎn)，隨后另一個微動開關(guān)動作發(fā)出無料信號，只要沒有物料阻擋檢測葉片的轉(zhuǎn)動，此種狀態(tài)也將一直保持下去。為防止使用中物料的沖擊，庫側(cè)安裝時應在檢測葉片上方的料倉內(nèi)壁上方安裝防護板；如采用加長軸頂置垂直安裝時，則應在軸套外安裝保護套筒。此種料位開關(guān)結(jié)構(gòu)簡單、價格低廉、維護方便，多用作粉狀物料料倉的料滿開關(guān)，但不適合高溫下工作。料位計推薦廠家料斗或儲倉中，固體物料內(nèi)部易存在大的孔隙，形成拱橋。粉料內(nèi)部易存在小的間隙。</p><div

雷達料位計利用回波測距原理，其喇叭狀或桿式天線向被測物料面發(fā)射微波，微波傳播到不同相對介電率的物料表面時被反射，并被天線接收。發(fā)射波和接收波的時間差與物料面和天線的間距成正比，測出傳播時間即可得知距離。 </p> <p> 優(yōu)點：由于微波是電磁波，以光速傳播且不受介質(zhì)特性影響，故在一些有溫度、壓力、蒸汽等場合，超聲波料位計不能正常工作，而雷達料位計可使用；此料位計大多為二線制的一體化產(chǎn)品，節(jié)省大量電纜；軟件調(diào)試方便。 </p> <p> 缺點：二線制雷達料位計要求24VDC電源質(zhì)量較高，交流諧波一般不能超過±30VAC；雷達料位計內(nèi)部電源模塊易受其他大電流干擾而損壞，故應把料位計停電拆除；測量固體物料，易產(chǎn)生干擾回波，降低測量效果，故不適用于固體物料的測量。 </p><p> 料位計的工藝特點：由于不同的工業(yè)生產(chǎn)過程的特點不同，所以料位計需針對不同的工藝條件來確定。為了能夠更明確地分析物位儀表，料位儀表的工作原理、特點和應用環(huán)境，必須對物位測量的工藝要求進行明確分析。 </p> <p> 首先我們來分析液位測量的工藝特點: </p> <p> 1.液面是規(guī)則表面。但當液體流進、流出時容易產(chǎn)生波動或生產(chǎn)過程中出現(xiàn)起泡、沸騰等變化時同樣也會產(chǎn)生波動。 </p> <p> 2.容器內(nèi)發(fā)生有液體各處密度、黏度或溫度等物理量不均勻的現(xiàn)象。 </p> <p> 3.容器內(nèi)發(fā)生有高壓、高溫、液體黏度過大、大量臟污雜質(zhì)、懸浮物等。 </p> <p> 固體物料的物理、化學性質(zhì)較復雜，如有顆粒狀的、也有粉末狀的，并且有些介質(zhì)為大小不均勻的顆粒;固體物料的含水量變化、溫度等也是不均勻的變化;料倉振動、料倉形狀不規(guī)則等。雷達料位計的頻率越高，發(fā)射角越小，單位面積上能量越**的衰減越小，雷達料位計的測量效果越好。</p><div style="width:100%;text-align:

雷達料位計：雷達料位計工作原理和超聲波料位計類似，它發(fā)射的微波是一種電磁波，其傳播速度不受介質(zhì)的特性影響。它是利用電磁波回波測距原理來實現(xiàn)料位測量的。微波從天線出發(fā)，到達被測目標經(jīng)反射再被天線接收，按微波來回傳播時間來計算的距離反映了料位。一般有脈沖雷達和調(diào)頻連續(xù)波雷達2種。由于受粉塵、料面坡度及物料松散程度的影響，微波在傳輸過程中會有衰減，影響其準確性和可靠性。某公司生產(chǎn)的纜式導波雷達可以解決傳統(tǒng)雷達料位計的上述缺點。它的原理是高頻脈沖從探頭發(fā)出后沿纜繩傳播，當脈沖遇到料位表面時將會反射回來，由jieshouqi接收，信號經(jīng)轉(zhuǎn)換成料位信號。由于微波沿纜繩傳播，脈沖的強度及方向性均不受粉塵及料面松散程度的影響。同時可通過軟件設計對干擾進行yizhi。其傳播纜繩經(jīng)過耐磨性、下拉力試驗，可以適應水泥廠的工況，此種料位計測量精度高，已在水泥廠成功應用。但產(chǎn)品價格高使應用范圍受限制。優(yōu)良的測量再現(xiàn)性和環(huán)境工況適應性：即不受物料粒度、形狀、比重、溫度、濕度、粉塵濃度等變化的影響。料位計哪家好</p><p style="text-indent:25px">雷達料位計雷達料位計具有比接觸式料位計和同類非接觸料位計更加優(yōu)良的性能。甘肅雙攬式雷達料位計推薦</p><p> 脈沖型和調(diào)頻連續(xù)波雷達：用于測物位的雷達料位計通常分為兩類：脈沖型雷達和調(diào)頻連續(xù)波雷達。在過程監(jiān)測場合主要選用脈沖型雷達，由于其頻率較低（6.3GHz），并且在天線結(jié)構(gòu)設計時充分考慮了冷凝、積料等影響，還能利用雷達料位計中的回波信號處理，在有攪拌器等復雜工況中也能識別有效回波，價格相對也較便宜，故在水泥行業(yè)中主要采用了雷達料位計．雷達由于發(fā)射功率大，量程大，價格也有較大下降，而且可靠性高，故近期在水泥行業(yè)已較多采用了國產(chǎn)雷達。甘肅雙攬式雷達料位計推薦</p><p
