<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。 </p> <p> 即：h= H–vt/2 </p> <p> 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)集成過程控制系統(tǒng)的時(shí)代.在許多生產(chǎn)過程中，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、煤粉倉、水泥庫和化學(xué)原料庫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。 </p> <p> 美國MONITOR雷達(dá)料位計(jì)依據(jù)時(shí)域反射原理(TDR Time Domain Reflectometry)為基礎(chǔ)的雷達(dá)料位計(jì)，時(shí)域反射原理首先是用于通訊電纜的故障檢測(cè)，我們將其成功應(yīng)用于工業(yè)測(cè)量領(lǐng)域。 </p> <p> 1.在罐上或儲(chǔ)存容器上的位置可以是在**或側(cè)部，只要在接觸不到的容器部位即可。 </p> <p> 2.避免傳感器與罐壁的接觸，萬一安裝在直徑小于100mm的靜止管中時(shí)，將需要現(xiàn)場(chǎng)標(biāo)定以保證對(duì)測(cè)量精確度，對(duì)于同軸版本，可以沒有問題的安裝而無需預(yù)防。 </p> <p> 3.避免安裝太靠近攪拌器，否則，軟纜/桿可能被纏住，在這種情況下，側(cè)面安裝的更可取些。 </p> <p> 4.在介質(zhì)絮亂的情況下，傳感器的末端要固定住。雷達(dá)料位計(jì)可以適應(yīng)高溫、高壓、蒸汽等惡劣的生產(chǎn)環(huán)境。</p><div style="width:100%;text-align: center;"><img

雷達(dá)料位計(jì)的基本原理 </p> <p> 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。雷達(dá)料位計(jì)安裝要求及調(diào)試?yán)走_(dá)波在空氣中是直線傳播，所以探頭安裝位置是否合適將直接影響到測(cè)量的結(jié)果。無錫透鏡式雷達(dá)料位計(jì)批發(fā)價(jià)格</p><p style="text-indent:25px">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。無錫透鏡式雷達(dá)料位計(jì)批發(fā)價(jià)格</p><p> 應(yīng)用中存在的問題及解決方法 </p> <p> 有些工況下所使用的雷達(dá)料位計(jì)，因?yàn)閭鞲衅靼惭b位置不當(dāng)及條件所致，出現(xiàn)了一些問題，下面將對(duì)一些使用中的問題提出解決方案,供大家參考。 </p> <p> 1．探頭結(jié)疤和頻繁故障的解決方法個(gè)辦法是將探頭安裝位置提高，但是有時(shí)候安裝條件限制，不能提高的情況下，就應(yīng)采用將料位測(cè)量值與該槽的泵聯(lián)鎖的辦法，解決這一難題：將比較高料位設(shè)定值減小0.5m左右，當(dāng)料位達(dá)到該比較高值時(shí)，即可停進(jìn)料泵或開啟出料泵。 </p> <p> 2．雷達(dá)料位計(jì)被淹相應(yīng)的改進(jìn)辦法解決這種問題的辦法是將雷達(dá)料位計(jì)改為導(dǎo)波管式測(cè)量。仍在原開孔處安裝導(dǎo)波管式雷達(dá)料位計(jì)，導(dǎo)波管高于排汽管0.2m左右，這樣一來，即使出現(xiàn)料漿從排汽管溢出的惡劣工況，也不會(huì)使料位計(jì)天線被料漿淹沒，而且避免了攪拌器渦流的干擾及大量蒸汽從探頭處冒出，減少了對(duì)探頭的損害，同時(shí)由于導(dǎo)波管聚焦效果好，接收的雷達(dá)波信號(hào)更強(qiáng)，取得了很好的測(cè)量效果。使用導(dǎo)波管測(cè)量方式，可以改善表計(jì)測(cè)量條件，提高儀表測(cè)量性能,具有很高的推廣應(yīng)用價(jià)值。無錫透鏡式雷達(dá)料位計(jì)批發(fā)價(jià)格</p></p><br
