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，膜片式液位控制器規(guī)格，膜片式液位控制器規(guī)格、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，膜片式液位控制器規(guī)格。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。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。膜片式液位控制器規(guī)格</p><div

style="text-indent:25px">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，采用擴散硅或陶瓷敏感元件的壓阻效應，將靜壓轉(zhuǎn)成電信號。經(jīng)過溫度補償和線性校正。轉(zhuǎn)換成4-20mADC標準電流信號輸出。不銹鋼浮球液位開關的傳感器部分可直接投入到液體中，變送器部分可用法蘭或支架固定，安裝使用極為方便。在工業(yè)生產(chǎn)中，不銹鋼浮球液位開關是一個非常重要的特殊控制系統(tǒng)，對工業(yè)生產(chǎn)有著重要的意義。目前，不銹鋼浮球液位開關被普遍應用到各個工業(yè)生產(chǎn)中，效果十分明顯。防水液位開關銷售液位開關包括浮球液位開關、浮球（浮筒）液位開關、浮球液位開關以及型液位開關等多種形式的液位檢測。</p><div

SUS304/316 zui高為 200 ℃。2 、壓力：塑膠類浮球耐壓較大 5kg/cm2 ， SUS 浮球耐壓zui大 30kg/cm2 。3 、粘著：應選用球大、比重小的浮球才能克服液體表面張力。4 、化性： PVDF 塑膠材質(zhì)適用于酸堿場所， H2SO4 硫酸如有溫度考慮時應選用 PVDF 。 PP 塑膠材質(zhì)適用于 HCl 鹽酸場所。 NBR 橡膠適用于油環(huán)境。 5 、油精：應使用不銹鋼金屬材質(zhì)。6 、比重：浮球比重 SG 必須小于被測液體，否則浮球浮不起來。7 、防護防爆等級：可根據(jù)客戶要求選擇各種接線盒，接線盒規(guī)格齊全，有塑膠、鋁合金、不銹鋼防爆型，防護等級可達 IP-65 以上。8 、電氣開關形式：接點容量 50W/250VACSPST 或 40W/250VACSPDT 。9 、安裝連接方式：接續(xù)法蘭有 JIS ， DIN ， ANSI 規(guī)格；螺紋牙口有 NPT ， PF ， BSP ， M ， UNC 等規(guī)格。</p><p style="text-indent:25px">液位開關安裝的時候主要看產(chǎn)品是屬于直裝式還是側(cè)裝式的，直裝式既可以頂裝也可以底裝，側(cè)裝式就是側(cè)面安裝，然后根據(jù)螺紋大小進行固定安裝，一般是M10的或者是根據(jù)自己的運行環(huán)境來決定大小也都是可以的，安裝其實是很簡單的。電極式液位開關是利用液體的導電性來監(jiān)測液位的高低，解釋接觸到棒極，便會導電從而輸出報警信號。電極式液位開關可多點控制，控制位置由客戶需求而定，具有突破保護功能，可有效防止突波干擾，不過電極式液位開關*適用于導電液體。電子式液位開關安裝所需空間小，安裝工藝簡單。</p><div

1、液位開關有很多種類，比如浮球液位開關，是在密閉的非導磁性管內(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，并輸出一個開關信號。2、液位開關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和外貼式超聲波液位開關，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。浮球液位開關建議使用電壓24V。防水液位開關銷售</p><p

style="text-indent:25px">耐高溫液位浮球開關選擇型號請依照被測物之使用溫度、壓力、比重、耐酸堿等特性，選用上表所列各種規(guī)格的浮球。耐高溫浮球液位開關選擇的七個方面：1、溫度：PVDF溫度為120℃，PP為80℃，SUS304/316為200℃。 2、壓力：塑膠類浮球耐壓5kg/cm2，SUS浮球耐壓30kg/cm2。 3、粘著：應選用球大、比重小的浮球才能克服液體表面張力。 4、化性：塑膠材質(zhì)適用于酸堿場所，如有溫度考慮時應選用PVDF。 5、油精：應使用金屬材質(zhì)。6、比重：浮球比重SG必須小于被測液體，否則浮球浮不起來。 7、電壓：220VAC/200VDC 電流：0.7A。膜片式液位控制器規(guī)格</p><p
