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。徐州專業(yè)生產(chǎn)80HZ調(diào)頻雷達(dá)料位計(jì)由于雷達(dá)料位計(jì)所具有的特點(diǎn)和優(yōu)點(diǎn)，使得雷達(dá)料位計(jì)備受青睞，廣泛應(yīng)用于許多行業(yè)和復(fù)雜工況的物位測(cè)量。</p><div

style="text-indent:25px">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。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(lái)，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。3．關(guān)于泡沫對(duì)測(cè)量的影響干泡沫和濕泡沫能將雷達(dá)波反射回來(lái)，對(duì)測(cè)量無(wú)影響；中性泡沫則會(huì)吸收和擴(kuò)散雷達(dá)波，因而嚴(yán)重影響回波的反射甚至沒有回波。當(dāng)介質(zhì)表面為稠而厚的泡沫時(shí)，測(cè)量誤差較大或無(wú)法測(cè)量，在這種工況下，雷達(dá)料位計(jì)不具有優(yōu)勢(shì)，這是其應(yīng)用的局限性。</p><p> 料位計(jì)主要分為兩大類： </p> <p> 連續(xù)型和開關(guān)式 </p> <p> 連續(xù)型有超聲波、導(dǎo)波雷達(dá) </p> <p> 開關(guān)式則種類較多，阻旋式料位計(jì)、音叉式料位計(jì)、電容式料位計(jì)、重錘式料位計(jì)、射頻導(dǎo)納料位計(jì)。 </p> <p> 其中阻旋式和音叉式料位計(jì)對(duì)使用場(chǎng)合要求較高，不耐沖擊、不能測(cè)粘稠物料，電容式應(yīng)該說(shuō)是克服了其他料位計(jì)的缺點(diǎn)，曾經(jīng)是行業(yè)的主流，可惜的是它也有致命的缺陷，就是不能識(shí)別假料，為了克服這個(gè)缺陷，在電容式的基礎(chǔ)上開發(fā)出了射頻導(dǎo)納料位計(jì)。 </p> <p> 料位計(jì)有模擬量輸出的料位計(jì)，開關(guān)量的料位計(jì)模擬量就是連續(xù)量的4-20mA 輸出的料位計(jì)，有超聲波料位計(jì)，雷達(dá)料位計(jì)，重錘料位計(jì)，電容料位計(jì)，開關(guān)量輸出的是開關(guān)的，如射頻導(dǎo)納料位開關(guān)，阻旋料位開關(guān)，音叉料位開關(guān)，振棒料位開關(guān)，膜片料位開關(guān)，傾斜料位計(jì)開關(guān)。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。</p><div

當(dāng)測(cè)量液態(tài)物料時(shí)，傳感器的軸線和介質(zhì)表面保持垂直；當(dāng)測(cè)量固態(tài)物料時(shí)，由于固體介質(zhì)會(huì)有一個(gè)堆角，傳感器要傾斜一定的角度。 </p> <p> (2) 盡量避免在發(fā)射角內(nèi)有造成假反射的裝置。特別要避免在距離天線近的1/3錐形發(fā)射區(qū)內(nèi)有障礙裝置（因?yàn)檎系K裝置越近，虛假反射信號(hào)越強(qiáng)）。若實(shí)在避免不了，建議用一個(gè)折射板將過強(qiáng)的虛假反射信號(hào)折射走。這樣可以減小假回波的能量密度，使傳感器較容易地將虛假信號(hào)濾出。 </p> <p> (3) 要避開進(jìn)料口，以免產(chǎn)生虛假反射。 </p> <p> (4) 傳感器不要安裝在拱形罐的中心處（否則傳感器收到的虛假回波會(huì)增強(qiáng)），也不能距離罐壁很近安裝，比較好安裝位置在容器半徑的1/2處。 </p> <p> (5) 要避免安裝在有很強(qiáng)渦流的地方。如：由于攪拌或很強(qiáng)的化學(xué)反應(yīng)等，建議采用導(dǎo)波管或旁通管測(cè)量。 </p> <p> (6) 若傳感器安裝在接管上，天線必須從接管伸出來(lái)。喇叭口天線伸出接管至少10mm。棒式天線接管長(zhǎng)度比較大100或250mm。接管直徑小250mm?？梢圆扇〖哟蠼庸苤睆降姆椒?，以減少由于接管產(chǎn)生的干擾回波。在雷達(dá)料位計(jì)比較好位置固定好法蘭或擰緊螺絲扣，若有不可缺少，改易嚴(yán)密封閉圈。鹽城雷達(dá)料位計(jì)廠家哪家好</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(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。山東透鏡式雷達(dá)料位計(jì)廠家直供</p></p><br /><p>文章來(lái)源地址: http://www.cdcfah.com/cp/2590020.html</p></div></div></div></div></div><div id="jolvsp2"
