id="azm3nuw" class="box"><p><p style="text-indent:25px">全自動洗衣機中一般采用的液位開關就是壓力式水位開關，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。浮球式液位開關的特點是有一個帶桿的浮球，微型液位控制器銷售，微型液位控制器銷售，隨著液位的變化，微型液位控制器銷售，浮球聯(lián)動的桿隨著變化，從而控制開關的閉合。工業(yè)上很早就利用浮子測量水塔中的水位了。光電液位開關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。微型液位控制器銷售</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="微型液位控制器銷售,液位開關" src="https://tyunfile.71360.com/UploadFile/yierdianzi/637407041969015593/1747328.png"></div><p style="text-indent:25px">液位開關的安裝三步驟：1、使用黑色和藍色的電線，浮球在上液位時，接點是不通的狀態(tài)，浮球在下液位時，接點是接通的狀態(tài)。2、使用黑色和黃色的電線，浮球在上液位時，接點是接通的狀態(tài)，浮球在下液位時，接點是不通的狀態(tài)。3、固定重錘的安裝，液位的控制高度是由液位開關的電纜在液體中的長度及重錘在電纜的位置決定的。固定液位開關重錘的方法是，先將重錘從非喇叭口一端的卡環(huán)拆下，將其套在電纜的適當位置上，再將電纜從重錘喇叭口一端穿入，套在電纜上的卡環(huán)就限定了重錘的位置。將電纜在容器外的適當處固定。微型液位控制器銷售電纜浮球液位開關的結構簡單而合理。</p><div

1、從溫度入手：要根據(jù)使用環(huán)境中液體的溫度來選擇液位開關，不同種類的液位開關的溫度不同，可以根據(jù)廠家的銘牌標識來進行選擇。2、從壓力入手：塑膠類浮球液位開關的耐壓5kg/cm2，而sus浮球液位開關的耐壓30kg/cm2。根據(jù)壓力的不同來選擇合適的液位開關。3、從粘著入手：應該選用浮球比較大，而且比重比較小的浮球型液位開關，這樣才能很好的克服液體表面的張力。4、從化性入手：塑膠材質(zhì)比較適合使用在酸堿強的場所，根據(jù)使用的場所，選擇不同材質(zhì)的液位開關。5、從比重入手：浮球的比重需要小于被測量的液體，否則會導致浮球無法浮起。6、防爆等級：可以根據(jù)客戶的要求選擇接線盒，而且接線盒的規(guī)格必須齊全，并且有塑膠、鋁合金和不銹鋼的防爆型。7、導桿的長度液位控制器安裝基準面到導桿底部的總長度。液位開關在使用過程中，要注意到操作規(guī)范性，以保證測量數(shù)據(jù)的準確性。</p><p style="text-indent:25px">音叉液位開關選型注意事項：1.在選型時，要確定被測介質(zhì)的屬性，如液體的腐蝕性、酸堿性。如果音叉液位開關長期在密閉的腐蝕性介質(zhì)的容器中工作，儀表長時間與腐蝕介質(zhì)接觸，此時就需要選擇相應的防腐型音叉液位開關以保證儀表能夠正常工作。2.要達到準確的測量效果，選型時還要留意液體的密度大小，并選擇與介質(zhì)密度相匹配的音叉液位開關。深圳計為自動化技術有限公司自主研發(fā)生產(chǎn)的音叉液位開關可測量的低介質(zhì)密度為0.5g/cm3。3.因為音叉液位開關的叉體需直接接觸被測介質(zhì)，不同的過程溫度需要選用不同型號的音叉液位開關。計為自動化設計的音叉液位開關，采用耐高溫設計，過程溫度高達250℃，可適應大部分工業(yè)環(huán)境的需求。電纜浮球液位開關具有無毒、耐腐蝕、安裝方便、使用壽命長等特點。</p><div

style="text-indent:25px">音叉液位開關接線及安裝：接線事項：每臺儀表帶有一組繼電器觸點（SPDT）單刀雙擲，繼電器*作為一個開關，不能直接帶動報警器或其他較大功率設備動作。所有控制信號均由電子單元頂部的端子排輸出。綠燈亮時表明繼電器工作正常，燈滅時繼電器處于報警狀態(tài)（在斷電或儀表出現(xiàn)故障時，繼電器也處于報警狀態(tài)）。接線事項：打開外殼上蓋，內(nèi)有接線端子、撥動開關、發(fā)光二極管LED，靈敏度調(diào)節(jié)鈕。靈敏度調(diào)節(jié)鈕順時針旋轉，靈敏度降低；逆時針旋轉，靈敏度增高。通常出廠時已標好無需調(diào)校，對于高粘度液體介質(zhì)，一般調(diào)低靈敏度。外測液位開關經(jīng)常使用于各種液體的液體檢測。無錫液位開關批發(fā)價</p><p

style="text-indent:25px">不銹鋼浮球液位開關安裝要求在敞口的容器中測量靜態(tài)液位時，把液位變送器直接投入到容器底部，在容器開口處用尼龍帶或三腳可調(diào)安裝架等將電纜線(接線盒)固定即可。不銹鋼浮球液位開關是基于所測液體靜壓與該液體高度成正比的原理。不銹鋼浮球液位開關使用時還需要注意以下三個方面：1、使用中發(fā)現(xiàn)異常，應關掉電源，停止使用，進行檢查或直接向企業(yè)技術部聯(lián)系。2、接供電電源時應嚴格按照我公司接線說明進行連接。3、液位變送器運輸、儲存時應恢復原包裝，存放在陰涼、干燥、通風的庫房內(nèi)。微型液位控制器銷售</p><p
