style="text-indent:25px">液位開關(guān)的安裝三步驟：1、使用黑色和藍(lán)色的電線，浮球在上液位時(shí)，接點(diǎn)是不通的狀態(tài)，浮球在下液位時(shí)，接點(diǎn)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(shí)，接點(diǎn)是接通的狀態(tài)，浮球在下液位時(shí)，接點(diǎn)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(guān)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(guān)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(dāng)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(dāng)處固定。電子式液位開關(guān)豎向安裝時(shí)，水位到達(dá)紅線就動(dòng)作，有一定的防波浪功能。磁性液位開關(guān)經(jīng)銷商</p><p

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(biāo)識(shí)來進(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(huì)導(dǎo)致浮球無法浮起。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)桿的長度液位控制器安裝基準(zhǔn)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(zhǔn)確性。微型液位控制器品牌</p><p
