<p> 壓力變送器是整個(gè)變送器行業(yè)zui主要的類型之一，這是壓力變送器應(yīng)用廣、功能性強(qiáng)等特點(diǎn)影響的。壓力變送器能夠?qū)?、液、原油等介質(zhì)進(jìn)行測量，廣泛應(yīng)用關(guān)于各工業(yè)領(lǐng)域之中。也正是因?yàn)槿绱?，壓力變送器的?xì)分種類也很多，不同類型壓力變送器的特點(diǎn)也不同。 </p> <p> 防爆型壓力變送器，是具有防爆功能的變送器，常見的防爆類型有本安防爆和隔離防爆。如果您的工作現(xiàn)場具有一定的危險(xiǎn)性，就必須選擇防爆型壓力變送器，例如石油、天然氣、化工行業(yè)等。 </p> <p> 防水型壓力變送器，我們都知道一般情況下壓力變送器的應(yīng)用場合不能有冷凝和結(jié)露現(xiàn)象的產(chǎn)生，如果現(xiàn)場環(huán)境潮濕，很容易造成壓力變送器內(nèi)部進(jìn)水，導(dǎo)致電路板的燒毀，壓力變送器無法正常使用。防水型壓力變送器就是針對這種特殊場合進(jìn)行設(shè)計(jì)的。其特別的設(shè)計(jì)結(jié)構(gòu)能夠使壓力變送器的防護(hù)等級到達(dá)IP68，這是防水等級標(biāo)準(zhǔn)的zui gao ji別。 </p> <p> 衛(wèi)生型壓力變送器，在一些特殊行業(yè)比如醫(yī)療，電容式壓力變送器特點(diǎn)，電容式壓力變送器特點(diǎn)、制藥和食品行業(yè)，我們不僅需要壓力變送器對生產(chǎn)流程進(jìn)行壓力檢測，還要確保整個(gè)環(huán)境的衛(wèi)生與清潔。采用316L不銹鋼耐腐蝕性強(qiáng)，平膜型的設(shè)計(jì)結(jié)構(gòu)易清理，解決了很多對衛(wèi)生環(huán)境有特殊要求工況的難題。大氣壓力變送器指的是，電容式壓力變送器特點(diǎn)，能將大氣重量轉(zhuǎn)換為電信號進(jìn)行輸出，并為我們提供查看數(shù)據(jù)的儀器儀表。電容式壓力變送器特點(diǎn)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="電容式壓力變送器特點(diǎn),壓力變送器" src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439170791016/8261680.png"></div><p> 在易燃易爆的工況場合下，考慮到現(xiàn)場的安全性，需要選擇具有防爆功能的壓力變送器。壓力變送器在防爆方式中有三種方式：控制易爆氣體、控制局限和控制yinbao源。 </p> <p> 控制易爆氣體：防爆壓力變送器工作原理是在一個(gè)密封的隔爆箱體內(nèi)，充滿不含易爆氣體的潔凈氣體或惰性氣體，并保持箱內(nèi)氣壓略高于箱外氣壓，將壓力變送器安裝在箱內(nèi)。 </p> <p> 控制局限：這種形式的工作原理是將防爆壓力變送器外殼設(shè)計(jì)為隔爆標(biāo)準(zhǔn)殼體，防爆壓力變送器設(shè)計(jì)時(shí)按隔爆標(biāo)準(zhǔn)的殼體，按規(guī)范嚴(yán)格設(shè)計(jì)、制造和裝配一切的管理辦法執(zhí)行工藝，使在殼體內(nèi)發(fā)作的不致于激發(fā)殼體外風(fēng)險(xiǎn)性氣體的。隔爆防爆辦法的設(shè)計(jì)與制造標(biāo)準(zhǔn)極端嚴(yán)厲，并且裝配、接線和維修的操作規(guī)程也十分嚴(yán)厲。該辦法決定了隔爆的電氣設(shè)備、儀表往往十分嚴(yán)格，操作須斷電等。

防爆型壓力變送器是通過被測的氣體或者液體的施壓，使得防爆壓力變送器的電阻值發(fā)生變化（電阻效應(yīng)），將測量的相對應(yīng)的信號轉(zhuǎn)化成相對應(yīng)的4~20mA輸出信號或者帶HART協(xié)議的數(shù)字信號以進(jìn)行通訊。防爆型壓力變送器安全防爆，可廣泛應(yīng)用于石化、電力、冶金、制藥、食品加工等行業(yè)。 </p> <p> 防爆型壓力變送器應(yīng)用的性危險(xiǎn)場所可分為0區(qū)、1區(qū)和2區(qū)。所謂0區(qū)是指在正常情況下，性氣體混合物連續(xù)的或長時(shí)間地存在的場所；1區(qū)是指在正常情況下，性氣體混合物有可能出現(xiàn)的場所，2區(qū)指的是在正常情況下，性氣體不可能出現(xiàn)或即使出現(xiàn)也只是短暫時(shí)間存在的場所。對于防爆型壓力變送器來說，對0區(qū)的防爆要求是為嚴(yán)格的。壓力變送器可以是本安型、隔爆型，需要注意的是，不管什么形式的防爆型壓力變送器，均需要有國家防爆檢測部門的核實(shí)、取得相關(guān)防爆證書方可使用。 </p> <p> 防爆型壓力變送器中本安型需要配合安全柵才能在有性混合物的危險(xiǎn)場所使用。安全柵是靠控制能量來達(dá)到防爆規(guī)定的。本質(zhì)安全型防爆壓力變送器為了安全起見，應(yīng)區(qū)別本質(zhì)安全回路及非本質(zhì)安全回路，把本質(zhì)安全回路的接線與其它的電氣回路的接線分開走線。 </p><p style="text-indent:25px">在選用壓力變送器之初，要對現(xiàn)場使用工況進(jìn)行分析，根據(jù)具體使用環(huán)境選擇適合的壓力變送器，還要采取適當(dāng)?shù)拇胧瑴p少環(huán)境對壓力變送器的影響。壓力變送器穩(wěn)定性有定量指標(biāo)，在超過使用期后，需要重新進(jìn)行標(biāo)定，以確保壓力變送器的性能是否發(fā)生變化。在某些要求壓力變送器能長期使用而又不能輕易更換或標(biāo)定的場合，所選用的壓力變送器穩(wěn)定性要求更嚴(yán)格，要能夠經(jīng)受住長時(shí)間的考驗(yàn)。壓力變送器穩(wěn)定性有著重要的意義，選擇高穩(wěn)定性的壓力變送器是非常有必要的。在高穩(wěn)定性能這個(gè)基礎(chǔ)前提下，才能制造出具有高準(zhǔn)確度、高可靠性等能力的壓力變送器。壓力變送器穩(wěn)定性對于生產(chǎn)的正常運(yùn)行以及壽命的使用都有著重要的影響。電流輸出是壓力變送器常用的一種信號輸出方式，這與它的性能特點(diǎn)有關(guān)。</p><div

style="text-indent:25px">由于壓力變送器測量介質(zhì)的復(fù)雜性與多樣性，很多情況都對壓力變送器有一定的防腐性要求。電容式壓力變送器特點(diǎn)</p><p> 壓力變送器問題分析歸納： </p> <p> 1、變送器要測量什么樣的壓力：先確定系統(tǒng)中要確認(rèn)測量壓力的zui大值，一般而言，需要選擇一個(gè)具有比zui大值還要大1.5倍左右的壓力量程的變送器。這主要是在許多系統(tǒng)中，尤其是水壓測量和加工處理中，有峰值和持續(xù)不規(guī)則的上下波動，這種瞬間的峰值能破壞壓力傳感器，持續(xù)的高壓力值或稍微超出變送器的標(biāo)定最大值會縮短傳感器的壽命，然而，由于這樣做會精度下降。于是，可以用一個(gè)緩沖器來降低壓力毛刺，但這樣會降低傳感器的響應(yīng)速度。所以在選擇變送器時(shí)，要充分考慮壓力范圍，精度與其穩(wěn)定性。 </p> <p> 2、什么樣的壓力介質(zhì)：我們要考慮的是壓力變送器所測量的介質(zhì),黏性液體、泥漿會堵上壓力接口，溶劑或有腐蝕性的物質(zhì)會不會破壞變送呂中與這些介質(zhì)直接接觸的材料。以上這些因素將決定是否選擇直接的隔離膜及直接與介質(zhì)接觸的材料。一般的壓力變送器的接觸介質(zhì)部分的材質(zhì)采用的是316不銹鋼,如果你的介質(zhì)對316不銹鋼沒有腐蝕性,那么基本上所有的壓力變送器都適合你對介質(zhì)壓力的測量.如果你的介質(zhì)對316不銹鋼有腐蝕性，那么我們就要采用化學(xué)密封起到保護(hù)壓力變送器,延長了壓力變送器的壽命.
