style="text-indent:25px">液位開關(guān)，也稱水位開關(guān)，液位傳感器，顧名思義，就是用來控制液位的開關(guān)。從形式上主要分為接觸式和非接觸式。常用的非接觸式開關(guān)有電容式液位開關(guān),接觸式的浮球式液位開關(guān)應用普遍。電極式液位開關(guān)，電子式液位開關(guān)，電容式液位開關(guān)也可以采用接觸式方法實現(xiàn). 簡單的說就是以開關(guān)的形式對流量進行控制。是一種新型的數(shù)字控制液壓閥，可以有很高的開關(guān)速度，可以對泵、缸進行伺服控制。由于控制電流是數(shù)字量，只有開和關(guān)，可以很方便的與計算機連接進行控制。改變開關(guān)的占空比就可以改變流量。類似于開關(guān)電源的占空比。上海電纜式浮球液位開關(guān)口碑液位開關(guān)就是通過液位來控制線路通斷的開關(guān)。</p><div

style="text-indent:25px">電容式液位計的優(yōu)點電容式液位計的測量主要就是依賴兩個電極之間的電容量變化，也就是說電容液位計的靈敏度是取決于兩個介質(zhì)，氣體、和液體的介電常數(shù)的差值。電容液位計的測量必須保證兩個介質(zhì)的介電常數(shù)保持一致，否則介電常數(shù)的變化會直接導致誤差的產(chǎn)生。電容式液位計的金屬棒電極都覆蓋有絕緣層，這樣可以避免因被測量介質(zhì)具有導電性而產(chǎn)生的測量誤差和安全隱患。電容液位計的體積較小，適用于一些高壓介質(zhì)的液位測量。電容液位計還具有遠傳和調(diào)節(jié)的配套功能。</p><p style="text-indent:25px">浮球液位開關(guān)是利用微動開關(guān)做接點輸出。當水平面以上揚線角度超過28°時，浮球液位開關(guān)內(nèi)部的鋼珠會滾動壓到微動開關(guān)或脫離微動開關(guān)，使液位開關(guān)ON或OFF的接點信號輸出。也有另一類浮球液位開關(guān)，利用**開關(guān)做接點輸出，當液位上升接觸浮球時，浮球以重錘為中心隨水位上升角度變化。當水面以上揚線角度超過10°時，液位開關(guān)便會有ON或OFF的接點信號輸出。其主要特點: 1、使用微動開關(guān)做接點輸出，接點容量10A/250VAC可直接起動電機設備。 2、歐規(guī)(HAR)橡膠電纜，耐候性佳、價格低、使用壽命長。 3、構(gòu)造簡單、不需保養(yǎng)、污水凈水皆可使用。 4、電纜線≦20米的長度皆可訂制。電極式液位開關(guān)，電子式液位開關(guān)，電容式液位開關(guān)也可以采用接觸式方法實現(xiàn)。</p><div
