雷達(dá)式料位計(jì)組成：它主要由發(fā)射和接收裝置、信號(hào)處理器、天線、操作面板、顯示、故障報(bào)警等幾部分組成。 </p> <p> 發(fā)射－反射－接收是雷達(dá)式料位計(jì)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(hào)。反射回來(lái)的信號(hào)仍由天線接收，雷達(dá)脈沖信號(hào)從發(fā)射到接收的運(yùn)行時(shí)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(shí)間。 </p><p> 自動(dòng)化儀表控制已進(jìn)入了計(jì)算機(jī)時(shí)代，進(jìn)入了所謂計(jì)算機(jī)集成過(guò)程控制系統(tǒng)的時(shí)代.在許多生產(chǎn)過(guò)程中，需要對(duì)物位進(jìn)行檢測(cè)和控制，以保證生產(chǎn)正常連續(xù)運(yùn)行，確保產(chǎn)品質(zhì)量。如鍋爐內(nèi)的水位，油罐、水塔和各種儲(chǔ)液罐的液位，糧倉(cāng)、煤粉倉(cāng)、水泥庫(kù)和化學(xué)原料庫(kù)中的料位以及高溫條件下連續(xù)生產(chǎn)中的鋁水、鋼水或鐵水的液位等。

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(lái)進(jìn)行料位檢測(cè)。電磁波的物理特性與可見(jiàn)光相似，傳播速度相當(dāng)于光速。其頻率為300MHz-3000GHz。電磁波可以穿透空間蒸汽、粉塵等干擾源，遇到障礙物易于被反射，被測(cè)介質(zhì)導(dǎo)電性越好或介電常數(shù)越大，回波信號(hào)的反射效果越好。雷達(dá)物位計(jì)(3張)發(fā)射－反射－接收是雷達(dá)式料位計(jì)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。反射回來(lái)的信號(hào)仍由天線接收，雷達(dá)料位計(jì)雷達(dá)脈沖信號(hào)從發(fā)射到接收的運(yùn)行時(shí)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(shí)間。雷達(dá)料位計(jì)的一種遠(yuǎn)傳方式就是配報(bào)警開(kāi)關(guān)，液位控制開(kāi)關(guān)由干簧管及電路模塊組成，結(jié)構(gòu)緊湊、堅(jiān)固耐用。天津雙腔雷達(dá)料位計(jì)</p><p style="text-indent:25px">雷達(dá)料位計(jì)適用于酸堿儲(chǔ)罐、漿料儲(chǔ)罐、固體顆粒、小型儲(chǔ)油罐。各類導(dǎo)電、非導(dǎo)電介質(zhì)、腐蝕性介質(zhì)。天津雙腔雷達(dá)料位計(jì)</p><p> <p> 粉狀物料的選型 </p> <p> 在水泥廠和粉磨站水泥庫(kù)一般有4～8個(gè)，在水泥廠還有生料均化庫(kù)和粉煤灰?guī)?，這些物料全是粉料，非常難測(cè)其料位。在庫(kù)里的粉料表面極為疏松，微波反射相當(dāng)困難，為此建議采用接觸型雷達(dá)料位計(jì),也可選用法蘭的帶有號(hào)角天線的非接觸型雷達(dá)料位計(jì)，它實(shí)際上是把纜繩既當(dāng)天線又作導(dǎo)波管，合二為一，微波脈沖從探頭發(fā)出后沿纜繩傳播，當(dāng)脈沖遇到物料表面時(shí)會(huì)被反射回來(lái)，其量程可達(dá)35m，被測(cè)物料的介電常數(shù)ε比較低為1.6,另外纜繩的耐磨和忍受的比較大下拉力，能滿足水泥廠各類粉料庫(kù)的檢測(cè)要求。目前已有許多水泥廠用纜式雷達(dá)料位計(jì)測(cè)量均化庫(kù)、水泥庫(kù)和粉煤灰?guī)斓牧衔?，取得較好的效果，如海螺荻港、浙江三獅、陜西耀縣、甘肅祁連山等水泥廠。
