style="text-indent:25px">射頻導納液壓開關具有安裝方便、測量準確、防止掛料、實用性強等特點。其工作原理如下：射頻導納液位開關是通過探頭感知其與儲罐體間電抗（容抗和阻抗）的變化實現(xiàn)物位的測量與控制的。其內部電子單元，由探頭測量極與空載罐體間的電抗共同構成平衡電橋電路并產生一個穩(wěn)定振蕩信號。當被測介質覆蓋探頭測量極時，會引起探頭測量極與罐體間的電抗變化導致電橋電路不平衡而停止產生振蕩信號，接著，后級電路檢測到這一變化從而輸出報警信號。該振蕩信號作為射頻信號施加在探頭測量極的同時，還會經過1:1的電壓跟隨器后送往探頭的保護極，測量極與保護極的射頻信號具有等電位、同相位、同頻率又互相隔離的特性。當探頭有掛料時，測量極與保護極之間由于沒有電勢差而形成電氣隔離確保保護極的信號變化不影響檢測，使探頭測量極上電抗的變化只能由探頭測量極與罐體間的物料決定，從而使探頭上的掛料不會影響正常的檢測。投入式液位開關報價非接觸式液位開關安裝時不需要考慮電源位置，增加了使用的靈活性。</p><div

style="text-indent:25px">射頻導納物位控制技術是一種從電容式物位控制技術發(fā)展起來的，防掛料、更可靠、更準確、適用性更廣的物位控制技術，“射頻導納”中“導納”的含義為電學中阻抗的倒數(shù)，它由阻性成分、容性成分、感性成分綜合而成，而“射頻”即高頻，所以射頻導納技術可以理解為用高頻測量導納。高頻正弦振蕩器輸出一個穩(wěn)定的測量信號源，利用電橋原理，以精確測量安裝在待測容器中的傳感器上的導納，在直接作用模式下，儀表的輸出隨物位的升高而增加。射頻導納技術與傳統(tǒng)電容技術的區(qū)別在于測量參量的多樣性、驅動三端屏蔽技術和增加的兩個重要的電路。射頻導納技術由于引入了除電容以外的測量參量，尤其是電阻參量，使得儀表測量信號信噪比上升，大幅度地提高了儀表的分辨力、準確性和可靠性測量參量的多樣性也有力地拓展了儀表的可靠應用領域。</p><p style="text-indent:25px">液位開關注意事項：1、重錘為要求才附上之配件。2、請將電纜線直接拉到控制箱，盡量避免使用中間接頭。若不得已而有接頭時，不可將電纜線接頭浸入液體中。3、未使用的電線必須予以絕緣。浮球液位開關怎么接線呢？1.我們需要明白浮球液位開關是怎樣來實現(xiàn)功能的，也就是它的工作原理。浮球液位開關是由干簧管與浮球組成，通過浮球內置磁鐵吸合干簧管觸點的閉合或者斷開，從而輸出信號報警，而干簧管觸點的兩頭分別焊接一條線。2.我們需要明白浮球液位開關內部結構的接線圖，明白一個液位控制是怎么連接線路的，兩個甚至三個液位點，內部的接線是怎樣的，這樣就完全可以明白怎么去接線了！如果是需要控制雙液位，一般則是出線四條，兩條線控制一個點。當然也可以出線三條，一條公共線，另外兩條分別對應一個點，另外馳誠電子所生產的浮球開關常規(guī)出現(xiàn)為：黑、紅、藍、白、黃等，如果出現(xiàn)兩個以上動作點，則按照線材以此往上類推。浮球液位開關內部還存在著磁鐵來產生開跟關的動作，從而根據液位來進行操控。</p><div
