雷達(dá)料位計(jì)的安裝：(1)當(dāng)測量液態(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。(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。(3)要避開進(jìn)料口,以免產(chǎn)生虛假反射。(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,安裝位置在容器半徑的1/2處。(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)波管或旁通管安裝方式。(6)若傳感器安裝在接管上,天線必須從接管伸出來。喇叭口天線伸出接管至少10mm。棒式天線接管長度100mm或250mm。接管直徑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。

電容式料位計(jì)：電容式料位計(jì)原理是插入料倉中的電極與料倉壁之間構(gòu)成電容器，當(dāng)倉內(nèi)物料料位變化引起電容量的變化時(shí)，通過轉(zhuǎn)換電路得到相應(yīng)的控制信號(hào)。因?yàn)殡娙萘渴沁B續(xù)變化的，因此該料位計(jì)可以用作連續(xù)式料位測量，也可用作料位開關(guān)，作為報(bào)警或喂料、卸料設(shè)備的輸入信號(hào)。該料位計(jì)有造價(jià)低、無機(jī)械磨損、安裝和維修方便等特點(diǎn)。傳統(tǒng)的方式是通過調(diào)頻振蕩電路實(shí)現(xiàn)電容量到頻率的轉(zhuǎn)換，又經(jīng)限幅放大及鑒頻器的線性化，得到相應(yīng)的電壓或電流信號(hào)。若使用一段時(shí)間后電極(探頭)上粘有物料，則往往會(huì)導(dǎo)致控制器誤動(dòng)作，現(xiàn)已由傳統(tǒng)的檢測電容量發(fā)展為檢測探頭與倉壁間導(dǎo)納的方式。依據(jù)量程的大小和控制方式的不同，電極設(shè)計(jì)成桿(棒)式或鋼纜(重型鋼纜)式，可應(yīng)用于各種料倉。現(xiàn)在的新型產(chǎn)品為全密封一體化安裝結(jié)構(gòu)，采用射頻振蕩器和數(shù)字集成電路，無運(yùn)動(dòng)機(jī)械部件，“數(shù)字標(biāo)定技術(shù)”使得用戶可以在空倉的狀態(tài)下一次完成標(biāo)定，功能齊全、性能可靠、控制及時(shí)、顯示直觀。安裝此類料位計(jì)時(shí)應(yīng)注意選取合適的安裝點(diǎn)，避開下料口；注意信號(hào)線的屏蔽和接地，防止干擾。但倉內(nèi)物料溫度、濕度、運(yùn)動(dòng)速度的變化以及物料粘掛倉壁和電極等因素的影響，引起電容介電常數(shù)的變化。雷達(dá)料位計(jì)應(yīng)用電磁脈沖進(jìn)行快速測量，精度高，抗干擾能力強(qiáng)。阻旋式料位計(jì)用途</p><p
