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(gè)或多個(gè)干簧管，然后將此管穿過(guò)一個(gè)或多個(gè)中空且內(nèi)部有環(huán)形磁鐵的浮球，液位的上升或下降會(huì)帶動(dòng)浮球一起移動(dòng)，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(dòng)作，并輸出一個(gè)開關(guān)信號(hào)。2、液位開關(guān)一般作為報(bào)警連鎖用，儲(chǔ)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(chǔ)罐上都只有一個(gè)液位計(jì)，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，防爆浮球液位開關(guān)供應(yīng)商，這個(gè)開關(guān)就是液位計(jì)的補(bǔ)充，畢竟比新加一個(gè)液位計(jì)成本低。3、液位變送器可以放到罐頂，像雷達(dá)液位計(jì)，防爆浮球液位開關(guān)供應(yīng)商、伺服液位計(jì)，防爆浮球液位開關(guān)供應(yīng)商、超聲波液位計(jì)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?jì)在罐下面加一個(gè)顯示表，便于觀察維護(hù)。電纜浮球液位開關(guān)的特點(diǎn)是性能穩(wěn)定可靠。防爆浮球液位開關(guān)供應(yīng)商</p><div

1、理論上講，音叉液位開關(guān)可以根據(jù)需要安裝在任何位置，但如果安裝在入料口位置而造成的測(cè)量誤差，甚至損壞儀表，所以，在安裝音叉液位開關(guān)時(shí)，應(yīng)盡量避開物料的進(jìn)出口進(jìn)行安裝。2、音叉液位開關(guān)既可水平安裝、也可垂直或傾斜安裝。但如果被測(cè)介質(zhì)較為粘稠性時(shí)，為減少或避免掛料現(xiàn)象的出現(xiàn)，應(yīng)將音叉液位開關(guān)垂直安裝。3、在安裝音叉液位開關(guān)時(shí)，為了使儀表更加準(zhǔn)確地檢測(cè)，應(yīng)使其叉體面和液體升降或流動(dòng)方向保持平行，以避免掛料現(xiàn)象的出現(xiàn)，防止介質(zhì)對(duì)叉體的阻力而產(chǎn)生測(cè)量數(shù)據(jù)有所偏差，提高測(cè)量的準(zhǔn)確性。4、當(dāng)電子部件存在損壞或失靈時(shí)，為使儀表能夠繼續(xù)正常工作，建議對(duì)音叉液位開關(guān)的電子部件進(jìn)行更換。在設(shè)計(jì)上，所有計(jì)為Ring—11音叉液位開關(guān)的電子部件都是通用的，能夠相互更換。電容式液位控制器供應(yīng)浮球液位開關(guān)是需要被安裝在水箱側(cè)面，從而來(lái)檢測(cè)液面的高低。</p><div

style="text-indent:25px">射頻導(dǎo)納液壓開關(guān)具有安裝方便、測(cè)量準(zhǔn)確、防止掛料、實(shí)用性強(qiáng)等特點(diǎn)。其工作原理如下：射頻導(dǎo)納液位開關(guān)是通過(guò)探頭感知其與儲(chǔ)罐體間電抗（容抗和阻抗）的變化實(shí)現(xiàn)物位的測(cè)量與控制的。其內(nèi)部電子單元，由探頭測(cè)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(gè)穩(wěn)定振蕩信號(hào)。當(dāng)被測(cè)介質(zhì)覆蓋探頭測(cè)量極時(shí)，會(huì)引起探頭測(cè)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(hào)，接著，后級(jí)電路檢測(cè)到這一變化從而輸出報(bào)警信號(hào)。該振蕩信號(hào)作為射頻信號(hào)施加在探頭測(cè)量極的同時(shí)，還會(huì)經(jīng)過(guò)1:1的電壓跟隨器后送往探頭的保護(hù)極，測(cè)量極與保護(hù)極的射頻信號(hào)具有等電位、同相位、同頻率又互相隔離的特性。當(dāng)探頭有掛料時(shí)，測(cè)量極與保護(hù)極之間由于沒(méi)有電勢(shì)差而形成電氣隔離確保保護(hù)極的信號(hào)變化不影響檢測(cè)，使探頭測(cè)量極上電抗的變化只能由探頭測(cè)量極與罐體間的物料決定，從而使探頭上的掛料不會(huì)影響正常的檢測(cè)。</p><p style="text-indent:25px">射頻導(dǎo)納物位控制技術(shù)是一種從電容式物位控制技術(shù)發(fā)展起來(lái)的，防掛料、更可靠、更準(zhǔn)確、適用性更廣的物位控制技術(shù)，“射頻導(dǎo)納”中“導(dǎo)納”的含義為電學(xué)中阻抗的倒數(shù)，它由阻性成分、容性成分、感性成分綜合而成，而“射頻”即高頻，所以射頻導(dǎo)納技術(shù)可以理解為用高頻測(cè)量導(dǎo)納。高頻正弦振蕩器輸出一個(gè)穩(wěn)定的測(cè)量信號(hào)源，利用電橋原理，以精確測(cè)量安裝在待測(cè)容器中的傳感器上的導(dǎo)納，在直接作用模式下，儀表的輸出隨物位的升高而增加。射頻導(dǎo)納技術(shù)與傳統(tǒng)電容技術(shù)的區(qū)別在于測(cè)量參量的多樣性、驅(qū)動(dòng)三端屏蔽技術(shù)和增加的兩個(gè)重要的電路。射頻導(dǎo)納技術(shù)由于引入了除電容以外的測(cè)量參量，尤其是電阻參量，使得儀表測(cè)量信號(hào)信噪比上升，大幅度地提高了儀表的分辨力、準(zhǔn)確性和可靠性測(cè)量參量的多樣性也有力地拓展了儀表的可靠應(yīng)用領(lǐng)域。音叉式液位開關(guān)是一種新型的液位開關(guān)。</p><div

1、從溫度入手：要根據(jù)使用環(huán)境中液體的溫度來(lái)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(biāo)識(shí)來(lái)進(jìn)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(lái)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(qiáng)的場(chǎng)所，根據(jù)使用的場(chǎng)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(cè)量的液體，否則會(huì)導(dǎo)致浮球無(wú)法浮起。6、防爆等級(jí)：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(zhǎng)度液位控制器安裝基準(zhǔn)面到導(dǎo)桿底部的總長(zhǎng)度。液位開關(guān)在使用過(guò)程中，要注意到操作規(guī)范性，以保證測(cè)量數(shù)據(jù)的準(zhǔn)確性。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(cè)。電容式液位控制器供應(yīng)</p><p
