1、根本型，根據(jù)浮力原理，浮子在丈量管內(nèi)隨液位的升降而上、下移動(dòng)，浮子內(nèi)的持久磁鋼通過(guò)耦合效果，驅(qū)動(dòng)紅、白色翻柱翻轉(zhuǎn)180°，液位上升時(shí)翻柱由白色轉(zhuǎn)為紅色，降低時(shí)由紅色轉(zhuǎn)為白色，然后完成液位指示。2、電遠(yuǎn)傳，在浮子液位計(jì)上裝置變送器，通過(guò)浮子上下移動(dòng)，經(jīng)磁耦合效果使導(dǎo)桿內(nèi)丈量元件順次動(dòng)作，取得電阻信號(hào)改變，轉(zhuǎn)換成0～10mA或4～20mA的標(biāo)準(zhǔn)信號(hào)輸出，與顯現(xiàn)外表或計(jì)算機(jī)連接，到達(dá)遠(yuǎn)傳意圖。 3、上下限開(kāi)關(guān)輸出，在液位計(jì)立管上由用戶(hù)設(shè)定上、下限方位裝置操控器，操控器內(nèi)帶有自保持效果的舌簧開(kāi)關(guān)，使用磁性浮子隨液位移動(dòng)使簧片開(kāi)關(guān)動(dòng)作時(shí)，完成報(bào)警或限位操控。機(jī)械液位開(kāi)關(guān)公司電纜浮球液位開(kāi)關(guān)利用重力與浮力的原理設(shè)計(jì)而成。</p><div

style="text-indent:25px">電纜式液位開(kāi)關(guān)如何接線(xiàn)？要檢測(cè)出電纜式液位開(kāi)關(guān)的線(xiàn)路分別是控制哪個(gè)液位點(diǎn)，然后依照檢測(cè)出來(lái)的結(jié)果對(duì)應(yīng)接線(xiàn)。電纜式液位開(kāi)關(guān)線(xiàn)路檢測(cè)方法:測(cè)量方法為準(zhǔn)備一個(gè)萬(wàn)用表，比如，出來(lái)黑、紅、藍(lán)三條線(xiàn)，首先，你把萬(wàn)用表調(diào)整到無(wú)阻值的擋，分別用夾頭夾住黑色與藍(lán)色，如果上揚(yáng)浮球響，而下落掉，則為常閉。接下來(lái)就分別夾住黑色與紅色、藍(lán)色與紅色測(cè)試，如果其中一組出線(xiàn)浮球上揚(yáng)不響，下落響的則可判斷出來(lái)三條線(xiàn)哪條是公共線(xiàn)，哪條是上水位或者下水位了。如果你需要控制水滿(mǎn)抽水，那只需要取一條黑色公共線(xiàn)與另外一條控制下水位的，而控制上水位的這條則不需要想接，反之亦然。電纜式液位開(kāi)關(guān)接線(xiàn)方法（實(shí)際顏色請(qǐng)以實(shí)物為準(zhǔn)）：1、使用黑色和藍(lán)色的電線(xiàn)，浮球在上液位時(shí)，接點(diǎn)是不通的狀態(tài)，浮球在下液位時(shí)，接點(diǎn)是接通的狀態(tài)。2、使用黑色和黃色的電線(xiàn)，浮球在上液位時(shí)，接點(diǎn)是接通的狀態(tài)，浮球在下液位時(shí)，接點(diǎn)是不通的狀態(tài)。</p><p style="text-indent:25px">浮球液位開(kāi)關(guān)的調(diào)試：浮球液位開(kāi)關(guān)在我們安裝前只需要重新標(biāo)定水位線(xiàn)。無(wú)法對(duì)開(kāi)關(guān)本身進(jìn)行調(diào)整的。這時(shí)用萬(wàn)用表測(cè)開(kāi)關(guān)狀態(tài)，在水線(xiàn)附近會(huì)隨水位高低通斷，這說(shuō)明沒(méi)問(wèn)題。只要保證安裝過(guò)程中與熱力設(shè)備的水位線(xiàn)一致就好了。比如SOR的液位開(kāi)關(guān)吧，一般在筒壁上都貼著水位線(xiàn)，我們把開(kāi)關(guān)泡在在水槽中，慢慢下沉，使水面逐漸靠近標(biāo)識(shí)線(xiàn)，靠近時(shí)會(huì)聽(tīng)到微動(dòng)開(kāi)關(guān)動(dòng)作的聲音。需要注意的是：高加液位開(kāi)關(guān)等的工作溫度高，里邊的水溫也高；高溫水的密度要小于室溫水密度。因而室溫水的動(dòng)作線(xiàn)比開(kāi)關(guān)標(biāo)識(shí)線(xiàn)要低些的。液位低報(bào)警接在常閉上(NC)，液位高接常開(kāi)(NO)。這類(lèi)開(kāi)關(guān)還是不難安裝的。液位開(kāi)關(guān)本身都會(huì)帶兩對(duì)以上的微動(dòng)開(kāi)關(guān)，分別輸出兩對(duì)常開(kāi)兩對(duì)常閉接點(diǎn)，在應(yīng)用時(shí)通常是"接通報(bào)警"。超聲波液位開(kāi)關(guān)內(nèi)部壓電晶體的叉形探頭中間是被空氣隔開(kāi)的。</p><div
