射頻導(dǎo)納料位儀由傳感器和控制儀表組成，傳感器可采用棒式、同軸或纜式探極安裝于倉(cāng)頂。傳感器中的脈沖卡可以把物位變化轉(zhuǎn)換為脈沖信號(hào)送給控制儀表，控制儀表經(jīng)運(yùn)算處理后轉(zhuǎn)換為工程量顯示出來(lái)，從而實(shí)現(xiàn)了物位的連續(xù)測(cè)量。 </p> <p> 對(duì)于電容液位開(kāi)關(guān)或射頻導(dǎo)納式液位開(kāi)關(guān)，宜采用水平安裝；用于連續(xù)測(cè)量的電容液位計(jì)或射頻導(dǎo)納式液位計(jì)，宜采用垂直安裝。 </p> <p> 射頻導(dǎo)納的原理 </p> <p> 射頻導(dǎo)納的原理是通過(guò)探頭感知其與儲(chǔ)罐體間電抗（容抗和阻抗）的變化實(shí)現(xiàn)物位測(cè)量和控制的。其內(nèi)部電子單元，由探頭測(cè)量極與空載罐體間的電抗共同構(gòu)成平衡電橋電路并產(chǎn)生一個(gè)穩(wěn)定振蕩信號(hào)，當(dāng)被測(cè)介質(zhì)覆蓋探頭測(cè)量極時(shí)，會(huì)引起探頭測(cè)量極與罐體間的電抗變化導(dǎo)致電橋電路不平衡而停止產(chǎn)生振蕩信號(hào)，后級(jí)電路檢測(cè)到這一變化從而輸出報(bào)警信號(hào)。樂(lè)山射頻導(dǎo)納料位開(kāi)關(guān)報(bào)價(jià)</p><div

1）避開(kāi)入料口 </p> <p> 在選擇射頻導(dǎo)納料位開(kāi)關(guān)的安裝位置時(shí)，應(yīng)避開(kāi)入料口安裝，以避免因安裝在入料口而造成的測(cè)量誤差，甚至導(dǎo)致儀表受損。 </p> <p> 2）防潮 </p> <p> 如果儀表需要安裝在戶外或有潮氣的環(huán)境中，為防止潮氣進(jìn)入儀表，在接入電纜之前，應(yīng)將電纜線向下彎曲，儀表在遇到下雨或存在冷凝現(xiàn)象時(shí)，雨水和冷凝水便會(huì)隨之，從而達(dá)到防潮的效果。 </p> <p> 3）安裝間距 </p> <p> 如果需要多臺(tái)儀表同時(shí)安裝于料倉(cāng)內(nèi)，應(yīng)保證儀表之間的安裝間距大于500mm，這樣就可以有效避免因儀表之間的探頭相互干擾所導(dǎo)致的測(cè)量不可靠的情形出現(xiàn)。 </p><p> 射頻導(dǎo)納料位開(kāi)關(guān)關(guān)于射頻導(dǎo)納 </p> <p> 一、射頻導(dǎo)納的概念 </p> <p> 射頻導(dǎo)納是一種從電容式物位技術(shù)發(fā)展起來(lái)的新型物位控制技術(shù)，是對(duì)電容式物位技術(shù)的升級(jí)，具有防掛料、更可靠、更準(zhǔn)確、適用性更廣的特點(diǎn)。想要了解射頻導(dǎo)納的概念，我們首先需要先知道射頻和導(dǎo)納的含義。射頻即高頻無(wú)線電波譜，而導(dǎo)納的含義則為電學(xué)中阻抗的倒數(shù)，它由電阻性成分、電容性成分、感性成分綜合而成，所以射頻導(dǎo)納可以理解為一種利用高頻（即射頻）電波來(lái)測(cè)量電子元件特性參數(shù)的儀表。
