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(cè)量方法，特別在液位測(cè)量。在水泥廠超聲波物位測(cè)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(chǔ)庫物位測(cè)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(huì)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(hào)；當(dāng)前超聲波物位測(cè)量*用于測(cè)量塊料或顆粒狀的物料，對(duì)粉倉料位的測(cè)量，由于粉倉料位表面在下料時(shí)非常疏松，對(duì)超聲波信號(hào)有較強(qiáng)的衰減，現(xiàn)未使用。九十年代末期，在過程檢測(cè)領(lǐng)域出現(xiàn)了高性能、低價(jià)格的微波物位計(jì)即雷達(dá)料位計(jì)，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?。晃锪系臏囟?、壓力、密度等幾乎不影響對(duì)其準(zhǔn)確的測(cè)量；現(xiàn)有雷達(dá)料位計(jì)在天線設(shè)計(jì)和形狀確保了接受回波的能量；另外現(xiàn)場(chǎng)調(diào)試也十分簡(jiǎn)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(jì)有其更優(yōu)越的性能，近幾年來，雷達(dá)料位計(jì)迅速、大量進(jìn)入了過程檢測(cè)儀表的市場(chǎng)，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(jì)統(tǒng)占物位測(cè)量的領(lǐng)域。吉林電石爐料倉料位計(jì)廠家自動(dòng)重錘探測(cè)式料位計(jì)由伺服電機(jī)、懸有重錘的鋼絲繩、料位發(fā)信裝置以及帶微機(jī)的顯示儀表所組成。</p><div

超聲波料位計(jì)：超聲波料位計(jì)裝置是利用聲納原理來確定容器內(nèi)物料料位的，是一種在線聲納定位設(shè)備。超聲波換能器發(fā)出的超聲波脈沖，通過空氣傳到物料的界面并被反射，測(cè)出超聲波脈沖從發(fā)射到換能器接收所用的時(shí)間，再根據(jù)空氣中的聲速，就可計(jì)算出換能器到物料面的距離，從而確定料位。物料表面的松散程度，對(duì)超聲波信號(hào)的衰減影響很大；若料倉中彌漫料塵時(shí)，超聲波會(huì)被料塵吸收，從而使信號(hào)有所衰減，且粉料粘附在換能器表面等原因都嚴(yán)重影響料位測(cè)量的準(zhǔn)確性。因此，超聲波料位測(cè)量裝置適合塊狀物料的連續(xù)料位監(jiān)測(cè)。為解決該類儀器的不足，某些生產(chǎn)廠家，通過采用新材料、新技術(shù)，提高了換能器發(fā)射強(qiáng)度，避免了換能器的掛料、堵塞現(xiàn)象，并能應(yīng)用于高溫環(huán)境。在控制電路設(shè)計(jì)中，增加鑒別真?zhèn)涡盘?hào)的功能，使研制的超聲波料位計(jì)成功應(yīng)用于水泥倉。筆者曾到北京某混凝土攪拌站現(xiàn)場(chǎng)考察過某大學(xué)聲學(xué)研究所的儀器，發(fā)現(xiàn)它安裝和使用方便，測(cè)量數(shù)據(jù)準(zhǔn)確。 </p><p> 導(dǎo)波式雷達(dá)料位計(jì)此為雷達(dá)料位計(jì)的一種變型，通常采用脈沖波方式工作。與雷達(dá)料位計(jì)不同微波脈沖不是通過空間傳播，而是通過1根（或2根）從倉頂伸入、直達(dá)倉底的導(dǎo)波體傳播。導(dǎo)波體可以是金屬硬桿或柔性金屬纜繩，微波脈沖沿桿或纜的外側(cè)向下傳播，在被測(cè)物料表面被反射，回波被天線接收，由發(fā)射與回波脈沖的時(shí)間差即可計(jì)算出傳播距離。 </p> <p> 優(yōu)點(diǎn)：與超聲波及雷達(dá)料位計(jì)相比，工作穩(wěn)定可靠；同雷達(dá)料位計(jì)一樣，反射信號(hào)的強(qiáng)度取決于被測(cè)物料的介電率或?qū)щ娐?，但?dǎo)波式可以測(cè)量更低介電率的物料。 </p> <p> 缺點(diǎn)：雙桿（纜）及同軸管式導(dǎo)波體由于電場(chǎng)能量集中，易受外部結(jié)構(gòu)影響；在桿之間（或管內(nèi)部）易積料，產(chǎn)生虛假回波，影響測(cè)量效果；埋在物料中的纜繩由于物料重力會(huì)產(chǎn)生較大的下拉力，造成纜繩被拉斷等故障。雷達(dá)波是一種特殊形式的電磁波，雷達(dá)料位計(jì)利用了電磁波的特殊性能來進(jìn)行料位檢測(cè)。</p><div

我們知道料位計(jì)和液位計(jì)都是用來測(cè)量物料的數(shù)據(jù)的，而液位開關(guān)和料位開關(guān)則是限位報(bào)警裝置，但是料位計(jì)和液位計(jì)的區(qū)別是什么呢?對(duì)此，小編給大家做了如下的介紹。 </p> <p> 在測(cè)量過程中，料位計(jì)和液位計(jì)都是經(jīng)常會(huì)被使用的測(cè)量?jī)x器，但是它們之前是有著區(qū)別的。通常，我們會(huì)叫窗口中液位介質(zhì)的高低作為液位，而窗口中固體或者顆粒物質(zhì)的高度叫做料位，而測(cè)量液位的儀表則是液位計(jì)，所以，料位計(jì)就是用來測(cè)量料位的儀表了，也就是固體或者顆粒物質(zhì)的高度。料位計(jì)是專門用來測(cè)量固體物質(zhì)的，而液位計(jì)是專門用來測(cè)量液體物質(zhì)的，企業(yè)可以根據(jù)具體的使用情況來選擇。那么料位開關(guān)和液位開關(guān)又有什么區(qū)別呢?料位開關(guān)也被稱為料位控制開關(guān)，主要是在容器中固體物料的高度達(dá)到了某一個(gè)上、下限之后，起到的檢測(cè)作用的傳感器。液位開關(guān)是指容器中液體的高度達(dá)到了上、下限值是，進(jìn)行檢測(cè)的傳感器。通常，液位傳感器是輸出繼電器的接點(diǎn)信號(hào)或者是集電極的開路信號(hào)。這兩種的區(qū)別在于，料位開關(guān)是用于固體的檢測(cè)的，而液位開關(guān)則是用于液體的檢測(cè)的。為能夠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(duì)物位測(cè)量的工藝要求進(jìn)行明確分析。吉林電石爐料倉料位計(jì)廠家</p><p
