style="text-indent:25px">音叉物位開關(guān)是一種新型物位控制開關(guān)，它主要是靠音叉，通過震動原理來測量物位高度。音叉式物位控制器的工作原理是通過安裝在音叉基座上的一對壓電晶體使音叉在一定共振頻率下振動。當(dāng)音叉與被測介質(zhì)相接觸時，音叉的頻率和振幅將改變，這些變化由智能電路來進(jìn)行檢測，處理并將之轉(zhuǎn)換為一個開關(guān)信號。音叉物位開關(guān)具有使用壽命長、性能穩(wěn)定、安全可靠，以及適應(yīng)性強(qiáng)、不需調(diào)校和免于維護(hù)等特點(diǎn)，主要普遍應(yīng)用于冶金、建材、化工、輕工、糧食等行業(yè)中物位的過程控制。粉末物位開關(guān)哪家好振動式物位開關(guān)采用壓電器件實(shí)現(xiàn)振動的驅(qū)動與檢測。</p><div

style="text-indent:25px">音叉物位開關(guān)的適應(yīng)性強(qiáng)：被測液體不同的電參數(shù)、密度對測量均不產(chǎn)生影響。結(jié)垢、攪動、湍流、氣泡、振動、中等粘度、高溫、高壓等惡劣條件對檢測也無影響。免于維護(hù)：由于音叉限位開關(guān)的檢測過程由電子電路完成，無活動部件，所以一經(jīng)安裝投運(yùn)便不需要維護(hù)。不需調(diào)校：由于音叉限位開關(guān)的檢測不受被測介質(zhì)電參數(shù)及密度的影響，所以無論測量何種液體都不需現(xiàn)場調(diào)校。音叉物位開關(guān)典型應(yīng)用，自來水、礦泉水、紙漿、膠水、染料。泥漿、堿溶液、酸溶液。啤酒、飲料、可產(chǎn)生氣體的液體。流動性好的固體粉料。</p><p style="text-indent:25px">射頻導(dǎo)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(hù)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(dǎo)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(hù)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(dá)桶壁。保護(hù)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(hù)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(dāng)探棒接觸到物料時，會產(chǎn)生一準(zhǔn)確的信號準(zhǔn)位，該信號準(zhǔn)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。音叉式物位限位開關(guān)是依靠壓電晶體驅(qū)動叉體振動的。</p><div

style="text-indent:25px">音叉物位開關(guān)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(shí)際所起的關(guān)鍵性作用不同，人們便習(xí)慣性的叫出了許多不同稱呼。音叉物位開關(guān)是物位開關(guān)的一種，主要利用音叉諧振原理來測量物位狀態(tài)，其獨(dú)特的叉體設(shè)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(guān)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(diǎn)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(guān)解決了長期以來電容式物位限位開關(guān)在使用中溫漂大、不易標(biāo)定的兩大難題。粉末物位開關(guān)哪家好</p><p style="text-indent:25px">物位開關(guān)通常采用側(cè)裝（在倉壁側(cè)面安裝）方式安裝于倉體側(cè)壁，對料位高度進(jìn)行上下限位置的檢測。粉末物位開關(guān)哪家好</p><p style="text-indent:25px">高溫音叉料位開關(guān)的應(yīng)用：從高溫音叉料位開關(guān)的上述特點(diǎn)可知，過程溫度高達(dá)250℃的高溫音叉料位開關(guān)，主要應(yīng)用于高溫環(huán)境下細(xì)小顆粒、粉末物料的測量，其在以下工況中應(yīng)用尤其普遍：1、聚酯切片PET的料位測量。由于干燥塔中PET料粒溫度達(dá)160℃，常溫音叉料位開關(guān)難以在這樣的高溫下工作，而Fork-11高溫音叉料位開關(guān)的過程溫度高達(dá)250℃，完全滿足高溫工況下的現(xiàn)場測量需求。2、四氯化鋯的料位測量，四氯化鋯溫度達(dá)到200℃，所以過程溫度高達(dá)250℃的高溫音叉料位開關(guān)是理想之選，能夠安全可靠地進(jìn)行料位測量。3、其他過程溫度范圍為150℃到250℃工況的（較低密度）顆粒、粉末等料位測量。粉末物位開關(guān)哪家好</p><p
