壓力變送器常用選用方法壓力變送器的輸出信號(hào)與壓力變量之間有一給定的連續(xù)函數(shù)關(guān)系（通常為線性函數(shù)）。為了保證您挑選的變送器符合現(xiàn)場(chǎng)的使用要求，選型時(shí)有幾點(diǎn)需要注意的地方： </p> <p> 1、測(cè)量壓力的類型:壓力類型首要有表壓、絕壓、差壓等；表壓是指以大氣壓力為基準(zhǔn)，小于或大于大氣壓力的壓力；絕壓是指以肯定壓力零位為基準(zhǔn)，高于肯定壓力零位的壓力；差壓是指兩個(gè)壓力之間的差值。 </p> <p> 2、準(zhǔn)確度等級(jí):變送器的測(cè)量誤差錯(cuò)按精度等級(jí)來劃分，實(shí)際使用過程中，依據(jù)測(cè)量誤差的需求并本著適用經(jīng)濟(jì)的原則進(jìn)行挑選。 </p> <p> 3、體系的比較大過載:體系的比較大過載應(yīng)小于變送器的過載維護(hù)極限，否則會(huì)影響商品的運(yùn)用壽命乃至損壞商品。2倍丈量規(guī)模的過載維護(hù)是我公司商品的規(guī)范裝備（也可依據(jù)客戶請(qǐng)求進(jìn)行定制）。 </p> <p> 4、測(cè)量范圍:一般按實(shí)際測(cè)量壓力為測(cè)量范圍的80%挑選。 </p>

src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439507441406/8167624.png"></div><p> 壓力變送器的接觸材質(zhì)： </p> <p> 一般情況下壓力變送器的測(cè)量介質(zhì)為氣體和液體，但是有一點(diǎn)是必須重點(diǎn)注意的，就是壓力變送器的測(cè)量介質(zhì)不管是氣體還是液體，必須要與壓力變送器的接觸材質(zhì)兼容。 </p> <p> 壓力變送器與被測(cè)介質(zhì)接觸部分有膜片、過程連接等部分。壓力變送器的膜片、卡箍、螺紋、外殼選用的是質(zhì)量的304不銹鋼和316L不銹鋼材質(zhì)。也就是說，壓力變送器測(cè)量的介質(zhì)要與304或316L兼容。壓力變送器選擇使用的304不銹鋼，是不銹鋼中常見的一種材質(zhì)，密度為7.93 g/cm3，業(yè)內(nèi)也叫做18/8不銹鋼。耐高溫800℃，具有加工性能好，韌性高的特點(diǎn)。304不銹鋼地用于制作要求良好綜合性能的設(shè)備和機(jī)件。為了保持不銹鋼所固有的耐腐蝕性，鋼必須含有18%以上的鉻,8%以上的鎳含量。壓力變送器選用的316L不銹鋼因其優(yōu)異的耐腐蝕性在儀器儀表行業(yè)有著一定的應(yīng)用，316L也是屬于18-8型奧氏體不銹鋼的衍生鋼種，添加有2～3%的Mo元素。316L的Mo含量使得該鋼種擁有優(yōu)異的抗點(diǎn)蝕能力，市場(chǎng)上現(xiàn)有的316L大部分是按照美標(biāo)來生產(chǎn)的。316與304在化學(xué)成分上的主要區(qū)別就是Mo的含量，316的耐腐蝕性更好些，比304在高溫環(huán)境下更耐腐蝕。所以在高溫環(huán)境下，工程師更傾向于選擇316材料的零部件。 </p><p> 壓力變送器輸出電流波動(dòng)或不穩(wěn)定故障: </p> <p> 壓力變送器在使用過程中會(huì)遇到輸出電流波動(dòng)或不穩(wěn)定的狀況。我們要如何進(jìn)行這種故障的維修呢？我們就結(jié)合壓力變送器輸出電流波動(dòng)或不穩(wěn)定的現(xiàn)象，來對(duì)壓力變送器進(jìn)行分析處理。壓力變送器輸出電流波動(dòng)，在DCS顯示曲線上是可以明顯地看到的。在進(jìn)行故障排查的時(shí)候，可以先將控制系統(tǒng)切換至手動(dòng)觀察波動(dòng)情況。如果測(cè)量曲線波動(dòng)仍很頻繁,應(yīng)該是工藝的原因。如果波動(dòng)減少了，則可能是壓力變送器的原因或PID參數(shù)整定不當(dāng)引起。壓力變送器輸出電流波動(dòng)很明顯，顯示時(shí)有時(shí)無(wú)，時(shí)高時(shí)低時(shí)，應(yīng)重點(diǎn)檢查測(cè)量回路的連接情況。認(rèn)真排查接線端子的螺釘有沒有松動(dòng)、氧化、腐蝕而造成接觸不良。如果懷疑壓力變送器有問題，可以在有流量或壓力的狀態(tài)下，把三閥組或取樣閥關(guān)閉,使變送器保持一個(gè)固定的差壓或壓力，觀察變送器的輸出電流是否穩(wěn)定,如果電流仍不穩(wěn)定則變送器有故障或有干擾。

alt="吉林恒壓供水壓力變送器推薦,壓力變送器" src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439707236328/5737160.png"></div><p> 壓力變送器的特殊類型： </p> <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(cè)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(chǎng)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(chǎng)合不能有冷凝和結(jié)露現(xiàn)象的產(chǎn)生，如果現(xiàn)場(chǎng)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(wú)法正常使用。防水型壓力變送器就是針對(duì)這種特殊場(chǎng)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(jí)到達(dá)IP68，這是防水等級(jí)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、制藥和食品行業(yè)，我們不僅需要壓力變送器對(duì)生產(chǎn)流程進(jìn)行壓力檢測(cè)，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(duì)衛(wèi)生環(huán)境有特殊要求工況的難題。壓力變送器的測(cè)量介質(zhì)一定要與其材質(zhì)兼容，一旦發(fā)現(xiàn)不兼容須馬上更換壓力變送器。陜西陶瓷芯壓力變送器推薦</p><p style="text-indent:25px">擴(kuò)散硅壓力變送器可替代傳統(tǒng)的遠(yuǎn)傳壓力表，霍爾元件、差動(dòng)變送器，并具有DDZ-Ⅱ及DDZ-Ⅲ型變送器性能。吉林恒壓供水壓力變送器推薦</p><p> 壓力變送器的零點(diǎn)漂移: </p> <p> 壓力變送器的零點(diǎn)漂移是影響壓力變送器性能的重要指標(biāo)，應(yīng)受到大家的重視。壓力變送器的零點(diǎn)漂移是指，在大氣壓的狀態(tài)下，壓力變送器的輸出信號(hào)偏離零值上下波動(dòng)的現(xiàn)象，也稱之為零漂。 </p> <p> 壓力變送器產(chǎn)生零點(diǎn)漂移的原因很多，如電源電壓不穩(wěn)、元器件參數(shù)變值、環(huán)境溫度變化等。其中zui主要的因素是溫度的變化，因?yàn)榫w管是溫度的敏感器件，當(dāng)溫度變化時(shí)，其參數(shù)UBE、β、ICBO都將發(fā)生變化，zui終導(dǎo)致放大電路靜態(tài)工作點(diǎn)產(chǎn)生偏移。此外，在諸因素中，zui難控制的也是溫度的變化。 </p> <p> 其次壓力變送器應(yīng)用場(chǎng)所海拔高，大氣壓力較低。如果壓力壓力變送器是在平原地區(qū)進(jìn)行檢定的，這樣就會(huì)形成一個(gè)壓力差，造成壓力變送器的零點(diǎn)漂移。 </p> <p> 第三種情況，當(dāng)壓力變送器管線內(nèi)氣體濕氣較大，且有負(fù)壓時(shí)，易造成零點(diǎn)漂移。 </p> <p> 還有，如果壓力變送器中存在電路虛焊的情況。也會(huì)產(chǎn)生零點(diǎn)漂移。 </p> <p> 在壓力變送器的使用壽命期間，如果出現(xiàn)零點(diǎn)漂移的狀況，可以發(fā)回生產(chǎn)廠家，進(jìn)行重新標(biāo)定，以確保壓力變送器的測(cè)量精度。吉林恒壓供水壓力變送器推薦</p><p
