id="pjvznlz" class="box"><p><p style="text-indent:25px">射頻導(dǎo)納液壓開關(guān)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(dǎo)納液位開關(guān)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(nèi)部電子單元，由探頭測量極與空載罐體間的電抗共同構(gòu)成平衡電橋電路并產(chǎn)生一個穩(wěn)定振蕩信號。當(dāng)被測介質(zhì)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(dǎo)致電橋電路不平衡而停止產(chǎn)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(jīng)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，高低液位控制器價格，高低液位控制器價格、同頻率又互相隔離的特性。當(dāng)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，高低液位控制器價格，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。液位開關(guān)安裝的時候主要看產(chǎn)品是屬于直裝式還是側(cè)裝式的。高低液位控制器價格</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高低液位控制器價格,液位開關(guān)" src="https://tyunfile.71360.com/UploadFile/yierdianzi/637407042000304229/7924103.png"></div><p style="text-indent:25px">液位開關(guān)在選擇時的主要考慮因素： 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(guān)，不同種類的液位開關(guān)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(guān)的耐壓5kg/cm2，而sus浮球液位開關(guān)的耐壓30kg/cm2。根據(jù)壓力的不同來選擇合適的液位開關(guān)。3、從粘著入手：應(yīng)該選用浮球比較大，而且比重比較小的浮球型液位開關(guān)，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(guān)。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(dǎo)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(dǎo)桿的長度液位控制器安裝基準面到導(dǎo)桿底部的總長度。液位開關(guān)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。擺桿液位控制器銷售購買液位開關(guān)一定要去正規(guī)的廠家。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高低液位控制器價格,液位開關(guān)" src="https://tyunfile.71360.com/UploadFile/yierdianzi/637407042072501474/7618755.png"></div><p style="text-indent:25px">連桿浮球液位開關(guān)的安裝使用說明：1.安裝位置應(yīng)遠離進水口，否則開關(guān)會因進水口的波動而造成誤動作。2.若開關(guān)裝置于容器池壁，可加裝L型角鋼支架。3.若開關(guān)裝置于攪拌區(qū)域，可安裝防波管或防波擋板。4.選擇管的內(nèi)徑大于浮球直徑的法蘭連接管。5.配線時建議使用多蕊電纜。6.被控制線路負載必須與浮球開關(guān)接點容量相匹配。7.被測液體的比重必須大于浮球比重。7.浮球的動作點已按客戶訂貨要求在出廠時調(diào)整好，請不要隨意調(diào)整浮球位置。</p><p style="text-indent:25px">浮球液位開關(guān)的調(diào)試：浮球液位開關(guān)在我們安裝前只需要重新標定水位線。無法對開關(guān)本身進行調(diào)整的。這時用萬用表測開關(guān)狀態(tài)，在水線附近會隨水位高低通斷，這說明沒問題。只要保證安裝過程中與熱力設(shè)備的水位線一致就好了。比如SOR的液位開關(guān)吧，一般在筒壁上都貼著水位線，我們把開關(guān)泡在在水槽中，慢慢下沉，使水面逐漸靠近標識線，靠近時會聽到微動開關(guān)動作的聲音。需要注意的是：高加液位開關(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。因而室溫水的動作線比開關(guān)標識線要低些的。液位低報警接在常閉上(NC)，液位高接常開(NO)。這類開關(guān)還是不難安裝的。液位開關(guān)本身都會帶兩對以上的微動開關(guān)，分別輸出兩對常開兩對常閉接點，在應(yīng)用時通常是"接通報警"。液位開關(guān)顧名思義，就是通過液位來控制線路通斷的開關(guān)。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高低液位控制器價格,液位開關(guān)" src="https://tyunfile.71360.com/UploadFile/yierdianzi/637407041978585471/3219107.png"></div><p style="text-indent:25px">液位開關(guān)的三大作用： 1、液位開關(guān)有很多種類，比如浮球液位開關(guān)，是在密閉的非導(dǎo)磁性管內(nèi)安裝有一個或多個干簧管，然后將此管穿過一個或多個中空且內(nèi)部有環(huán)形磁鐵的浮球，液位的上升或下降會帶動浮球一起移動，從而使該非導(dǎo)磁性管內(nèi)的干簧管產(chǎn)生吸合或斷開的動作，并輸出一個開關(guān)信號。2、液位開關(guān)一般作為報警連鎖用，儲罐上用的比較多的是浮球液位開關(guān)和外貼式超聲波液位開關(guān)，一般我們儲罐上都只有一個液位計，但是重要的聯(lián)鎖我們往往要做2/2 或2/3的邏輯選擇程序，這個開關(guān)就是液位計的補充，畢竟比新加一個液位計成本低。3、液位變送器可以放到罐頂，像雷達液位計、伺服液位計、超聲波液位計等你想放下了也不行，現(xiàn)在用的比較多的是罐頂?shù)囊何挥嬙诠尴旅婕右粋€顯示表，便于觀察維護。液位開關(guān)有ON或OFF的接點信號輸出。高低液位控制器價格</p><p style="text-indent:25px">連桿浮球液位開關(guān)與小型浮球液位開關(guān)原理基本相同。高低液位控制器價格</p><p style="text-indent:25px">音叉液位開關(guān)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(guān)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(yīng)的防腐型音叉液位開關(guān)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(guān)。深圳計為自動化技術(shù)有限公司自主研發(fā)生產(chǎn)的音叉液位開關(guān)可測量的低介質(zhì)密度為0.5g/cm3。3.因為音叉液位開關(guān)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(guān)。計為自動化設(shè)計的音叉液位開關(guān)，采用耐高溫設(shè)計，過程溫度高達250℃，可適應(yīng)大部分工業(yè)環(huán)境的需求。高低液位控制器價格</p></p><br
