style="text-indent:25px">光電液位開關(guān)是使用紅外線探測的，利用光線的折射及反射原理，光線在兩種不同介質(zhì)的分界面將產(chǎn)生反射或折射現(xiàn)象。當(dāng)被測液體處于高位時則被測液體與光電開關(guān)形成一種分界面，當(dāng)被測液體處于低位時，則空氣與光電開關(guān)形成另一種分界面，這兩種分界面使光電開關(guān)內(nèi)部光接收晶體所接收的的反射光強(qiáng)度不同，即對應(yīng)兩種不同的開關(guān)狀態(tài)。電子式液位開關(guān)工作電壓是DC5V-24V，通過內(nèi)置電子探頭對水位進(jìn)行檢測，再由芯片對檢測到的信號進(jìn)行處理，當(dāng)被測液體的液位到達(dá)動作點(diǎn)時，輸出DC5V-24V，可以直接與PLC配合使用或者與控制板配合使用，頂裝液位開關(guān)供應(yīng)商，頂裝液位開關(guān)供應(yīng)商，從而實(shí)現(xiàn)對液位的控制。電子式液位開關(guān)當(dāng)橫向安裝時，頂裝液位開關(guān)供應(yīng)商，水位到達(dá)藍(lán)線就動作，且精度較高。頂裝液位開關(guān)供應(yīng)商</p><div

style="text-indent:25px">液位開關(guān)浮球接線圖由電纜在液體中的長度：液位的控制高度是由電纜在液體中的長度及重錘在電纜的位置決定的。使用棕色和黑色的電線：浮球在下液位時，接點(diǎn)是接通的狀態(tài)。浮球在上液位時，接點(diǎn)是不通的狀態(tài)。使用棕色和藍(lán)色的電線：浮球在上液位時，接點(diǎn)是接通的狀態(tài)。浮球在下液位時，接點(diǎn)是不通的狀態(tài)。未使用的電線必須絕緣。浮球液位開關(guān)建議使用電壓24V。1、將浮球開關(guān)的電纜線從重錘的中心下凹圓孔處穿入后，輕輕推動重錘使嵌在圓孔上方的塑膠環(huán)因電纜頭之推力而脫落。（如果有必要的話，也可用螺絲起子把此一塑膠環(huán)拆下）。再將這個脫落的塑膠環(huán)套在電纜上你所想固定生重錘以設(shè)定液之位置。2、輕輕地推動重錘拉出電纜，直到重錘中心扣住塑膠環(huán)，重錘只要輕扣在塑膠環(huán)上即不會滑落，此塑膠環(huán)如有損壞或遺失，可用同徑裸銅線扣入電纜代替。頂裝液位開關(guān)供應(yīng)商液位開關(guān)在安裝前應(yīng)當(dāng)予以確認(rèn)，檢查無誤后，才開始實(shí)行具體的安裝工作。</p><div

style="text-indent:25px">外貼式超聲波液位開關(guān)采用超聲波檢測技術(shù)，解決了傳統(tǒng)的液位開關(guān)的不足，不受液體表面的泡沫、水汽的影響。側(cè)貼式超聲波液位開關(guān)利用超聲波在管壁介質(zhì)中的余震信號，大幅度提高了穩(wěn)定性和穿透性，可適用于多種材料的容器，包括：合金鋼、不銹鋼、塑料、玻璃及各種合成材料。外貼非接觸式超聲波液位開關(guān)提供了容器尤其是高壓、腐蝕、密閉容器物位測量的解決方案，將探頭緊貼于容器外側(cè)壁，不需要打孔，即可完成單點(diǎn)物位測量，這種技術(shù)不受介質(zhì)壓力、溫度、泡沫、氣體、反射系數(shù)等因素的影響，所以適用于醫(yī)藥，石油，化工，電力，食品等行業(yè)的各類液體液位工程控制，對于有毒的、強(qiáng)腐蝕危險品液體的檢測，該產(chǎn)品更是理想的選擇，可滿足多種應(yīng)用需求和適應(yīng)各種惡劣環(huán)境。同時，具有極高可靠性，高穩(wěn)定性。</p><p style="text-indent:25px">全自動洗衣機(jī)中一般采用的液位開關(guān)就是壓力式水位開關(guān)，它裝在洗滌缸的上部，它有一根下端開口的氣管通到缸底，進(jìn)水時管里的空氣被封閉在里面出不來，就形成比外界稍高的壓力。水位越高壓力越高，這樣根據(jù)壓力就可間接測知水位。而壓力的測量仍然用彈性元件，靠元件的變形帶動觸點(diǎn)完成通斷動作。這種測液位的方法叫做“靜壓法”，在工業(yè)中用的不少。浮球式液位開關(guān)的特點(diǎn)是有一個帶桿的浮球，隨著液位的變化，浮球聯(lián)動的桿隨著變化，從而控制開關(guān)的閉合。工業(yè)上很早就利用浮子測量水塔中的水位了。液位開關(guān)包括浮球液位開關(guān)、浮球（浮筒）液位開關(guān)、浮球液位開關(guān)以及型液位開關(guān)等多種形式的液位檢測。</p><div

style="text-indent:25px">電容式液位開關(guān)是依據(jù)電容感應(yīng)原理，當(dāng)被測介質(zhì)浸汲測量電極的高度變化時，引起其電容變化。它可將各種物位、液位介質(zhì)高度的變化轉(zhuǎn)換成標(biāo)準(zhǔn)電流信號，遠(yuǎn)傳至操作控制室供二次儀表或計算機(jī)裝置進(jìn)行集中顯示、報警或自動控制。（1）在使用過程中，如果儀表無電流輸出，應(yīng)檢查信號處理器“+”，“-”引出線是否松動，脫落，儀表指示表頭固定螺紋及固定柱是否松有動，接觸不良。如果出現(xiàn)以上的問題應(yīng)該立即進(jìn)行加固。（2）如果儀表指示為零，用手握金屬工具，如鑷子、螺絲刀等，接觸信號處理器“傳感器”端子，儀表指示應(yīng)增大，否則表明儀表信號處理器損壞。此時要進(jìn)行儀表信號處理器的更換。（3）如果儀表指示打滿，將信號處理器“傳感器”引線取下，若儀表指示燈依然打滿，表明信號處理器損壞，若儀表指示回零，則可能是傳感器絕緣不良。絕緣不好時應(yīng)該立即更換傳感器。（4）檢查傳感器方法：將傳感器引出線從信號處理器取下。用500V搖表或500型萬用表“x10k”檔測量傳感器引出線與金屬塔壁間電阻，應(yīng)大于10M歐，否則表明傳感器絕緣不良。購買液位開關(guān)一定要去正規(guī)的廠家。頂裝液位開關(guān)供應(yīng)商</p><p
