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(guò)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(shuō)，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(jiàn)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，高溫型壓力變送器聯(lián)系方式，高溫型壓力變送器聯(lián)系方式。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(lái)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。如果壓力變送器的電源小于7，高溫型壓力變送器聯(lián)系方式.5VDC，則應(yīng)檢查回路中是否有大的負(fù)載。高溫型壓力變送器聯(lián)系方式</p><div

吉林無(wú)線(xiàn)壓力變送器價(jià)格查詢(xún)影響壓力變送器長(zhǎng)期穩(wěn)定性的因素除壓力變送器本身結(jié)構(gòu)外，還有就是變送器的使用環(huán)境。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="高溫型壓力變送器聯(lián)系方式,壓力變送器" src="https://tyunfile.71360.com/UploadFile/xalunqian/637328438873701172/3612278.png"></div><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(chēng)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(xiàn)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。 </p><p> 壓力變送器的內(nèi)部結(jié)構(gòu)主要指得是其殼體內(nèi)部的各種元器件，這也是壓力變送器性能好壞的主要因素。主要包括：固定銅片、集成芯片、隔離環(huán)、擴(kuò)散硅芯體、阻尼等。 </p> <p> 固定銅片： </p> <p> 在技術(shù)較為成熟、品質(zhì)較好的壓力變送器產(chǎn)品中，都會(huì)在內(nèi)部添加固定銅片。固定銅片能夠很好的提高絕緣度、抗震性和接地穩(wěn)定性。部分廉價(jià)壓力變送器為節(jié)約成本則不會(huì)添加固定銅片。 </p> <p> 集成芯片： </p> <p> 集成芯片的品質(zhì)能夠很好的保障壓力變送器的抗干擾性和穩(wěn)定性。良好壓力變送器的集成芯片都是采用國(guó)際先進(jìn)的集成芯片，散件拼裝的電路芯片抗干擾性差，穩(wěn)定性差。 </p> <p> 隔離環(huán)： </p> <p> 壓力變送器添加隔離環(huán)能夠提高產(chǎn)品的絕緣度，對(duì)壓力變送器起到很好的保護(hù)作用。 </p> <p> 擴(kuò)散硅芯體： </p> <p> 先進(jìn)的壓力變送器采用進(jìn)口國(guó)際先進(jìn)硅晶圓擴(kuò)散硅芯體，這是壓力變送器高精度高、長(zhǎng)期穩(wěn)定性的保障。壓力變送器的價(jià)格差別主要體現(xiàn)在這個(gè)上邊。劣質(zhì)芯體長(zhǎng)期穩(wěn)定性差，也不能保證壓力變送器的測(cè)量精度。 </p> <p> 阻尼： </p> <p> 在壓力變送器內(nèi)部添加阻尼，為的是提高其抗沖擊的性能，更好的對(duì)壓力變送器內(nèi)部其他結(jié)構(gòu)進(jìn)行防護(hù)，避免瞬間的過(guò)壓對(duì)壓力變送器造成沖擊損壞。起到很好的保護(hù)作用。 </p> <p> <br /> </p> <p> <br />

</p> <p> 情況二：如果我們的壓力變送器輸出信號(hào)為0.5～2.5V DC的輸出信號(hào)或者采用RS485輸出信號(hào)時(shí)，壓力變送器的供電電壓應(yīng)定制3～5V DC。 </p> <p> 情況三:如果我們采用的是防爆型壓力變送器本安防爆型或粉塵本質(zhì)安全型，壓力變送器的供電電壓就需要選用本安電源24V DC。 </p> <p>
