在選擇射頻導納料位開關的安裝位置時，應避開入料口安裝，以避免因安裝在入料口而造成的測量誤差，廣元射頻導納料位開關批發(fā)，廣元射頻導納料位開關批發(fā)，廣元射頻導納料位開關批發(fā)，甚至導致儀表受損。 </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，為防止潮氣進入儀表，在接入電纜之前，應將電纜線向下彎曲，儀表在遇到下雨或存在冷凝現(xiàn)象時，雨水和冷凝水便會隨之，從而達到防潮的效果。 </p> <p> 3）安裝間距 </p> <p> 如果需要多臺儀表同時安裝于料倉內，應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致的測量不可靠的情形出現(xiàn)。廣元射頻導納料位開關批發(fā)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

射頻導納是一種從電容式物位技術發(fā)展起來的新型物位控制技術，是對電容式物位技術的升級，具有防掛料、更可靠、更準確、適用性更廣的特點。想要了解射頻導納的概念，我們首先需要先知道射頻和導納的含義。射頻即高頻無線電波譜，而導納的含義則為電學中阻抗的倒數(shù)，它由電阻性成分、電容性成分、感性成分綜合而成，所以射頻導納可以理解為一種利用高頻（即射頻）電波來測量電子元件特性參數(shù)的儀表。

在安裝之前，請再次確認儀表的供電電壓、過程溫度、介質的化學性能等是否滿足現(xiàn)場的環(huán)境要求，以確保儀表與工況相匹配，在安裝后能夠正常使用。 </p> <p> 2、安裝方式 </p> <p> 射頻導納料位開關的安裝主要有水平安裝和垂直安裝兩種方式。 </p> <p> 1）水平安裝 </p> <p> 在大多數(shù)情況下，射頻導納料位開關均采水平安裝，這樣可以保證測量的準確性。如果測量允許存在幾厘米的誤差，可將射頻導納料位開關向下傾斜約20°后安裝，以有效避免因物料在探頭上的堆積所造成的測量誤差（注：纜繩型射頻導納料位開關禁止水平安裝）。 </p> <p> 在物料沖擊較強的應用場合下，安裝時還需要增加防護擋板（如圖1所示），以保證儀表更可靠地工作。巴中射頻導納料位開關</p><p
