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(guò)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(guò)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(mǎn)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(lèi)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 /> </p><p> 料位是工業(yè)生產(chǎn)中的一個(gè)重要參數(shù)。料位測(cè)量的方法很多，針對(duì)不同的工況和介質(zhì)可以使用不同測(cè)量原理的料位計(jì)，吹氣法、靜壓式、浮球式、重錘式、超聲波等幾種常用的料位測(cè)量?jī)x表，都有各自的特點(diǎn)和應(yīng)用范圍。 </p> <p> 雷達(dá)料位計(jì)運(yùn)用先進(jìn)的雷達(dá)測(cè)量技術(shù)，以其優(yōu)良的性能，尤其是在槽罐中有攪拌、溫度高、蒸汽大、介質(zhì)腐蝕性強(qiáng)、易結(jié)疤等惡劣的測(cè)量條件下，顯示出其的性能，在工業(yè)生產(chǎn)中發(fā)揮著越來(lái)越重要的作用。 </p> <p> 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。雷達(dá)料位計(jì)是先進(jìn)的測(cè)量?jī)x表，適用于固體料、過(guò)程容器或強(qiáng)粉塵易結(jié)晶、結(jié)露場(chǎng)合。</p><div

安裝雷達(dá)物位計(jì)時(shí)要避免傳感器和罐壁的接觸，應(yīng)該和管壁保持一定距離。因?yàn)槔走_(dá)物位計(jì)是通過(guò)發(fā)出高頻微波脈沖沿著探測(cè)組件傳播測(cè)量的，這些脈沖波遇到被測(cè)介質(zhì)介電常數(shù)就會(huì)發(fā)生變化，引起反射。因此，要是安裝的物位計(jì)離管壁過(guò)近就可能得到的是管壁的介電常數(shù)，直接導(dǎo)致了被測(cè)參數(shù)的不準(zhǔn)確。 </p> <p> 雷達(dá)物位計(jì)的正確安裝方法 </p> <p> 1、建議安裝短管的外壁距離罐體內(nèi)壁應(yīng)該大于罐體直徑的1/6； </p> <p> 2、安裝短管的外壁距離罐體內(nèi)壁的距離小不得低于300mm； </p> <p> 3、不能將雷達(dá)物位計(jì)安裝在入料口的上方； </p> <p> 4、不能安裝在罐體中心位置，如果安裝在**，會(huì)產(chǎn)生多重虛假回波，干擾回波會(huì)導(dǎo)致信號(hào)丟失。 </p> <p> 5、如果不能保持儀表與罐壁的距離，罐壁上的介質(zhì)會(huì)黏附造成虛假回波，在調(diào)試儀表的時(shí)候應(yīng)該進(jìn)行虛假回波存儲(chǔ)。耐溫高（200℃）雷達(dá)料位計(jì)對(duì)于安裝空間有一定的要求。重慶高頻雷達(dá)料位計(jì)銷(xiāo)售廠家</p><p

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。重慶高頻雷達(dá)料位計(jì)銷(xiāo)售廠家</p></p><br
