style="text-indent:25px">浮球液位開關(guān)結(jié)構(gòu)主要基于浮力和靜磁場原理設(shè)計生產(chǎn)的。帶有磁體的浮球（簡稱浮球）在被測介質(zhì)中的位置受浮力作用影響：液位的變化導致磁性浮子位置的變化。浮球中的磁體和傳感器（磁簧開關(guān)）作用，產(chǎn)生開關(guān)信號。音叉液位開關(guān)的工作原理是通過安裝在基座上的一對壓電晶體使音叉在一定共振頻率下振動。當音叉液位開關(guān)的音叉與被測介質(zhì)相接觸時，音叉的頻率和振幅將改變，音叉液位開關(guān)的這些變化由智能電路來進行檢測，處理并將之轉(zhuǎn)換為一個開關(guān)信號，達到液位報警或控制的目的。為了讓音叉伸到罐內(nèi)，通常使用法蘭或者帶螺紋的工藝接頭將音叉開關(guān)安裝到罐體的側(cè)面或者頂部。</p><p style="text-indent:25px">射頻導納物位開關(guān)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(guān)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。振動式物位開關(guān)有振棒料位開關(guān)、音叉料位開關(guān)、音叉液位開關(guān)和緊湊型音叉液位開關(guān)幾種。</p><div

style="text-indent:25px">物位開關(guān)按所測介質(zhì)的不同，可以分為料位開關(guān)和液位開關(guān)兩種。但無論是何種形式的物位開關(guān)，在安裝前都應認真閱讀并嚴格按照產(chǎn)品說明書的安裝要求進行操作，從而避免因安裝不當所導致的儀表無法穩(wěn)定工作的情況出現(xiàn)。為使儀表用戶更好地應用物位開關(guān)，物位開關(guān)的安裝須知，供儀表用戶參考。一般小型阻旋料位開關(guān)是一種結(jié)構(gòu)簡單、使用方便、安全可靠的小型料位開關(guān)。外表美觀，小巧。主要用在小型料倉料斗上。主要使用在工廠自動給料系統(tǒng)或生產(chǎn)線上。選用物位開關(guān)時還需根據(jù)被測物料溫度，選擇與之相適應的耐溫產(chǎn)品。常用物位開關(guān)</p><p style="text-indent:25px">振動式物位開關(guān)能很好適應非常低的密度以及濕度變化和介電常數(shù)不穩(wěn)定的介質(zhì)測量。常用物位開關(guān)</p><p style="text-indent:25px">物位開關(guān)的輸出方式應怎樣選擇？　響應時間：數(shù)十毫秒級。壽命：隨帶負載電流的增加而減少，一般在幾十萬次至一百萬次之間，有的公司產(chǎn)品可達100萬次以上。優(yōu)點：不同公共點之間可帶不同的交、直流負載，且電壓也可不同，帶負載電流可達8A/點。晶體管是一種電子元件，它是通過基極電流來控制集電極與發(fā)射極的導通，屬于無觸點元件。其輸出響應速度快，但是有極性要求，所以只能帶直流負載。優(yōu)點：適應于高頻動作，響應時間短，一般為0.2ms左右電子開關(guān)裝置，噪音小，反映時間短，壽命長。常用物位開關(guān)</p><p
