style="text-indent:25px">90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，其頻率范圍為300MHz～300GHz,微波的傳播速度為3×108m/s,如設(shè)頻率為5.8GHz,在大氣中波長(zhǎng)約為52mm，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?。粚?duì)被測(cè)固體物料除要求其介電常數(shù)ε>1.8外，物料的溫度、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(lái)，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，據(jù)統(tǒng)計(jì)近幾年來(lái)新設(shè)計(jì)的大型水泥廠和粉磨站的各類庫(kù)和倉(cāng)近90％采用了各種類型的雷達(dá)料位計(jì)，還成功用在云南紅塔滇西水泥公司的3條水泥生產(chǎn)線的8個(gè)水泥庫(kù)中，和其他儀表組成了新型的FCS系統(tǒng)。雷達(dá)料位計(jì)可以應(yīng)用在礦山行業(yè)物料過程存儲(chǔ)物位檢測(cè)，如粗破倉(cāng)、細(xì)碎倉(cāng)和粉礦倉(cāng)等料倉(cāng)。</p><div

從雷達(dá)料位計(jì)的測(cè)量原理可以知道，雷達(dá)料位計(jì)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(shí)間來(lái)測(cè)量料位的，在反射信號(hào)中混合有許多干擾信號(hào)，所以，對(duì)真實(shí)回波的處理和對(duì)各種虛假回波的識(shí)別技術(shù)就成為雷達(dá)料位計(jì)能夠準(zhǔn)確測(cè)量的關(guān)鍵因素。 </p> <p> (2)測(cè)量數(shù)據(jù)處理： </p> <p> 由于液面波動(dòng)和隨機(jī)噪聲等因素的影響，檢測(cè)信號(hào)中必然混有大量噪聲。為了提高檢測(cè)的準(zhǔn)確度，必須對(duì)檢測(cè)信號(hào)進(jìn)行處理，盡可能消除噪聲。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(duì)測(cè)量的影響。 </p> <p> (3)雷達(dá)料位計(jì)的特點(diǎn)： </p> <p> 由于雷達(dá)料位計(jì)采用了上述先進(jìn)的回波處理和數(shù)據(jù)處理技術(shù)，加上雷達(dá)波本身頻率高，穿透性能好的特點(diǎn)，所以，雷達(dá)料位計(jì)具有比接觸式料位計(jì)和同類非接觸料位計(jì)更加優(yōu)良的性能。 </p> <p> ①可在惡劣條件下連續(xù)準(zhǔn)確地測(cè)量。 </p> <p> ②操作簡(jiǎn)單，調(diào)試方便。 </p> <p> ③準(zhǔn)確安全且節(jié)省能源。 </p> <p> ④無(wú)需維修且可靠性強(qiáng)。 </p> <p> ⑤幾乎可以測(cè)量所有介質(zhì)。 </p> <p> <br /> </p> <p> <br />
