style="text-indent:25px">射頻導納物位開關測量原理：會遇到有物料附著于其上情形，并在三個電極間形成電容與電阻，因主電極與保護電極間的電位及波形一樣，所以不會有電流通過兩電極的介質(zhì)，導納式物位開關利用以上的原理，于主電極與接地電極間置一保護電極，以阻擋射頻電流經(jīng)由主電極與接地電極間的介質(zhì)而到達桶壁。保護電極與接地電極間雖然會有少量的射頻電流通過，但電路并不會偵測此一電流值。由于保護電極的作用，只有介于主電極與桶壁間所通過的射頻電流變化會被電路所偵測，因此當探棒接觸到物料時，會產(chǎn)生一準確的信號準位，該信號準位的大小與介電系數(shù)成正比，但與電阻值成反比，此信號很容易被電路偵測出來，并輸出一控制信號。</p><p style="text-indent:25px">物位開關使用指南：(1）探頭長度：探頭長度為安裝螺紋前端到探頭前端的距離，訂購加長型探頭時，探頭長度為上述距離；(2）輸出接線：輸出接線輸出指示為輸出的換開關置于“NC”位置時的輸出，置于“NO”位置時，常閉端與常開端互換；物位開關安裝和維護：（1）應避開入料口處安裝；（2）在顆粒直徑大于15mm的塊體或距離入料口下部7米以下安裝時，應加探頭護蓋；（3）測定粘度較大的粉粒體時，應從溶器的上部向下垂直或從側(cè)壁部斜向下較深插入安裝；（4）探頭使用溫度超過120 C時，由于壓電元件壽命縮短，所以應定期檢測開關動作是否正常。物位開關采用壓電元件內(nèi)置于棒體和厚管壁的不銹鋼管的探頭。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="三位控制開關售價,物位開關"

style="text-indent:25px">音叉物位開關也常被稱作音叉物位計或者音叉物位控制器，主要是因為音叉物位計在工業(yè)生產(chǎn)中的不同環(huán)節(jié)出現(xiàn)，實際所起的關鍵性作用不同，人們便習慣性的叫出了許多不同稱呼。音叉物位開關是物位開關的一種，主要利用音叉諧振原理來測量物位狀態(tài)，其獨特的叉體設計及其固有的振動特性，能保證音叉的自動掃除功能并較大限度地防止掛料。音叉式物位開關振幅可調(diào)，便于測量不同狀態(tài)和密度的物料，適用于各種料倉固體物料料位以及各種容器內(nèi)液位的定點檢測報警或控制。固體物料：粉煤灰、水泥、石粉、塑料顆粒、鹽、糖等。液體介質(zhì)：水、酸、堿、泥漿、燃料、油類、牛奶、酒類、飲料等。特性：測量介質(zhì)：干燥顆粒、粉狀物料及各種液體、漿體等。物位開關側(cè)裝時螺紋安裝管盡可能得短，使探極螺紋端部和槽內(nèi)壁齊平，避免根部積料。三位控制開關售價</p><p
