料位計的工藝特點(diǎn)：由于不同的工業(yè)生產(chǎn)過程的特點(diǎn)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(diǎn)和應(yīng)用環(huán)境，必須對物位測量的工藝要求進(jìn)行明確分析。 </p> <p> 首先我們來分析液位測量的工藝特點(diǎn): </p> <p> 1.液面是規(guī)則表面。但當(dāng)液體流進(jìn)、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(xué)性質(zhì)較復(fù)雜，如有顆粒狀的，新疆高溫雷達(dá)料位計、也有粉末狀的，新疆高溫雷達(dá)料位計，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。電容式液位計是將被測量對象位置的變化轉(zhuǎn)換成電容量的一種裝置，新疆高溫雷達(dá)料位計，電容液位計具有結(jié)構(gòu)簡單，分辨力高。新疆高溫雷達(dá)料位計</p><div

超聲波技術(shù)近幾年來發(fā)展很快，是目前應(yīng)用廣的非接觸式測量方法，特別在液位測量。在水泥廠超聲波物位測量已較普遍應(yīng)用在原料調(diào)配庫、原煤庫、熟料庫等，但超聲波必須借助于介質(zhì)傳播，如在水泥廠的儲庫物位測量通常以空氣作為傳播介質(zhì)，而空氣的溫度、濕度的變化會影響超聲波傳播速度，空氣中的粉塵也將衰減超聲波的傳播信號；當(dāng)前超聲波物位測量*用于測量塊料或顆粒狀的物料，對粉倉料位的測量，由于粉倉料位表面在下料時非常疏松，對超聲波信號有較強(qiáng)的衰減，現(xiàn)未使用。九十年代末期，在過程檢測領(lǐng)域出現(xiàn)了高性能、低價格的微波物位計即雷達(dá)料位計，所謂微波是電磁波，其穿透力強(qiáng)，傳播速度不受粉塵、蒸汽及介質(zhì)組分的影響，傳播衰減也很小；物料的溫度、壓力、密度等幾乎不影響對其準(zhǔn)確的測量；現(xiàn)有雷達(dá)料位計在天線設(shè)計和形狀確保了接受回波的能量；另外現(xiàn)場調(diào)試也十分簡單，通過**的軟件，能把正確的回波迅速找到，并立即換算為物位值。由于比超聲料位計有其更優(yōu)越的性能，近幾年來，雷達(dá)料位計迅速、大量進(jìn)入了過程檢測儀表的市場，在各行業(yè)普遍使用。在水泥行業(yè)也幾乎由雷達(dá)料位計統(tǒng)占物位測量的領(lǐng)域。新疆高溫雷達(dá)料位計雷達(dá)料位計是非接觸式測量或TDR導(dǎo)波式測量。</p><div

雷達(dá)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(diǎn)：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(dá)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(diǎn)：二線制雷達(dá)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(dá)料位計內(nèi)部電源模塊易受其他大電流干擾而損壞，故應(yīng)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> 料位計在靜電除塵中的應(yīng)用 </p> <p> 除塵器的灰斗是收塵設(shè)備中比較關(guān)鍵的一個部件，它將除塵過程中的廢塵收集起來，以應(yīng)用的廣的布袋式除塵器來說，當(dāng)進(jìn)氣口的含大量灰塵的煙氣在強(qiáng)大的負(fù)壓下碰撞到阻擋灰塵的布袋上時，質(zhì)量較大的部分直接落入灰斗中，而質(zhì)量小的灰塵附著在布袋表面，在反吹風(fēng)或脈沖噴氣閥氣流的外力作用下機(jī)械抖動以達(dá)到清灰的過程，清理的灰塵全都落入灰斗中，長期處于工況中的除塵器一般都是連續(xù)工作，在線分室清灰，這時大量的被清理的灰塵源源不斷地落入灰斗中，灰斗的容積卻是有限的，所以必須在灰斗中灰塵裝滿之前就要有一個反饋信號給PLC系統(tǒng)，以便安排時間清理掉灰斗里的灰塵以便繼續(xù)工作，這時一般灰斗部分會加裝一個可控的卸灰閥方便將灰塵轉(zhuǎn)移出來。以上過程中的反饋信號就要靠料位計來產(chǎn)生了，料位計是安裝在灰斗中的探測灰塵在灰斗中的位置的儀器，有了它就可以知道灰斗中的灰有多少了，以便組織工作。料位計可分為射頻導(dǎo)納式物位控制器、重錘式料位計、阻移式物位計等。阻旋式料位計采用機(jī)電位控原理，接觸測量料位。</p><div

從雷達(dá)料位計的測量原理可以知道，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，在反射信號中混合有許多干擾信號，所以，對真實(shí)回波的處理和對各種虛假回波的識別技術(shù)就成為雷達(dá)料位計能夠準(zhǔn)確測量的關(guān)鍵因素。 </p> <p> (２)測量數(shù)據(jù)處理： </p> <p> 由于液面波動和隨機(jī)噪聲等因素的影響，檢測信號中必然混有大量噪聲。為了提高檢測的準(zhǔn)確度，必須對檢測信號進(jìn)行處理，盡可能消除噪聲。 </p> <p> 經(jīng)過大量的實(shí)驗(yàn)驗(yàn)證，采用數(shù)據(jù)平滑方法可以達(dá)到滿意的效果。此方法也可有效的克服罐內(nèi)攪拌器對測量的影響。雷達(dá)料位計適用于酸堿儲罐、漿料儲罐、固體顆粒、小型儲油罐。各類導(dǎo)電、非導(dǎo)電介質(zhì)、腐蝕性介質(zhì)。新疆高溫雷達(dá)料位計</p><p
