<p> 在壓力變送器的使用過程中需要電源為其供電，通常情況下我們?nèi)粘Ｉ钪杏玫降碾妷簽?20V的交流電（AC），對于壓力變送器而言，需要連續(xù)輸出穩(wěn)定的信號，直流電(DC)在方向和大小上都是穩(wěn)定的，不會隨時間發(fā)生改變，交流電則恰恰相反。這就是大多數(shù)壓力變送器采用直流電的原因。錯誤的選擇壓力變送器的供電電壓，會損壞壓力變送器的電路板，新疆高溫型壓力變送器，這也是導(dǎo)致壓力變送器出現(xiàn)故障的主要原因之一。采用多大的供電電壓是壓力變送器的一個重要的問題。 </p> <p> 壓力變送器的常規(guī)供電電壓為12～36V DC,采用此范圍的供電電壓可以有效的避免因電壓過高造成損壞，選擇此范圍的供電電壓也比較符合現(xiàn)在主流設(shè)備，方便壓力變送器與其它設(shè)備系統(tǒng)進(jìn)行對接、組合使用。習(xí)慣上24V DC的供電電壓用在壓力變送器中應(yīng)用的比較多，新疆高溫型壓力變送器， 24V DC能夠適應(yīng)大多數(shù)傳輸和負(fù)載需求（帶 250Ω×2個負(fù)載和 1KM 傳輸距離），高了浪費(fèi)低了應(yīng)用受限制，新疆高溫型壓力變送器，當(dāng)然如果有需要完全可以改變供電電壓。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 變送器高頻噪聲通過變壓器主要不是靠初、次級線圈的互感耦合，而是靠初、次級寄生電容耦合的。新疆高溫型壓力變送器</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="新疆高溫型壓力變送器,壓力變送器"

一般情況下壓力變送器的測量介質(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> 差壓變送器的選購指南。 </p> <p> 第一步：差壓變送器量程；不管我們選擇什么樣的差壓變送器，先要確認(rèn)的就是差壓量程、單端靜壓。因?yàn)榱砍痰牟町悾苯佑绊懖顗鹤兯推鬟x擇的類型不同。 </p> <p> 第二步：差壓變送器所處環(huán)境；影響差壓變送器的環(huán)境因素有兩個，一是環(huán)境溫度和濕度，二是現(xiàn)場干擾情況。差壓變送器對溫度和濕度都是有嚴(yán)格要求的。像是室內(nèi)環(huán)境中應(yīng)用的差壓變送器，選擇變送器環(huán)境溫度在-40～85℃之間，環(huán)境濕度在0%～95%RH之間即可。在戶外使用或超過上述范圍、現(xiàn)場有雨水或露水淋濺時，就要考慮用價格更貴的3051型差壓變送器。 </p> <p> 第三步：差壓變送器被測介質(zhì)；差壓變送器實(shí)際測量的介質(zhì)必須要與變送器接觸材質(zhì)兼容。以免損壞或腐蝕變送器元器件。 </p> <p> 第四步：差壓變送器的防爆性；防爆參數(shù)是差壓變送器的一個重要技術(shù)參數(shù)，現(xiàn)場有防爆要求的必須采用防爆型差壓變送器。防爆的類型也有所不同，有本安防爆、隔離防爆、粉塵防爆等不同要求。 </p> <p> 第五步：差壓變送器的顯示功能：因具體使用需求的差別，需不需要差壓變送器的顯示功能，也是要進(jìn)行選擇的。帶顯示差壓變送器能實(shí)時監(jiān)測差壓的測量值，當(dāng)然，帶顯示的價格會比不帶顯示的高一些。 </p> <p> <br /> 壓力變送器根據(jù)傳感器種類，可分為電容式壓力變送器、擴(kuò)散硅壓力變送器、單晶硅壓力變送器。</p><div

src="https://tyunfile.71360.com/UploadFile/xalunqian/637328439390527344/2017285.png"></div><p> 不同類型壓力變送器使用注意事項(xiàng)： </p> <p> 壓力變送器經(jīng)過長期的市場應(yīng)用和技術(shù)研發(fā)，其成員不斷擴(kuò)大。針對一些特定使用場合的壓力變送器越來越多。這符合整個變送器行業(yè)發(fā)展細(xì)分化的需求。不同類型的壓力變送器不僅在特點(diǎn)上有差異，在注意事項(xiàng)上也是有一定的區(qū)別的。向大家講解一下特殊類型壓力變送器的一些使用注意事項(xiàng)。 </p> <p> 高溫型壓力變送器：在使用過程中注意不要讓介質(zhì)溫度超過壓力變送器的工作溫度。必要時，需加裝冷卻裝置（冷凝管、盤管）。 </p> <p> 防爆型壓力變送器：本安防爆型壓力變送器必須配備安全柵和本安電源才可在危險場所使用。 </p> <p> 防水型壓力變送器：為了抵消大氣壓力，線纜內(nèi)部配有導(dǎo)氣管，產(chǎn)品接線處必須保障干燥通風(fēng)。 </p> <p> 衛(wèi)生型壓力變送器：衛(wèi)生型壓力變送器底部膜片采用的是無近壓孔、無腔平面結(jié)構(gòu)。需要注意壓力變送器的膜片非常脆弱，千萬不能用外物碰觸！膜片變形可以導(dǎo)致測量誤差不準(zhǔn)確，如膜片損壞壓力變送器則無法使用。如果被測量是多維向量，則要求變送器的交叉靈敏度越小越好。新疆高溫型壓力變送器</p><p style="text-indent:25px">影響壓力變送器長期穩(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。新疆高溫型壓力變送器</p><p style="text-indent:25px"><p>壓力變送器是一款常用的變送器類型。具有精度高、穩(wěn)定性好、響應(yīng)速度快、抗干擾能力強(qiáng)，結(jié)構(gòu)小巧、安裝方便等優(yōu)點(diǎn)。壓力變送器的電路是整個儀表中重要的組成部分，電路的正常與否影響著壓力變送器的工作狀態(tài)。我們?nèi)绾螌毫ψ兯推鞯碾娐愤M(jìn)行檢查呢？下面來看具體分析。<p>狀況一：將壓力變送器接通電源，當(dāng)壓力變送器輸入壓力信號后，檢查輸出端電壓信號的狀態(tài)。<p>若無輸出電壓，應(yīng)首先檢查電源電壓是否正常，是否符合供電要求，電源與壓力變送器及負(fù)載設(shè)備之間有無接線錯誤。如果壓力變送器接線端子上無電壓或極性接反均可造成變送器無電壓信號輸出。<p>線路板接插件有無接觸不良現(xiàn)象，可采取對照正常儀表的測量電壓與故障儀表對應(yīng)的測量電壓相比較的方法，確定故障點(diǎn)。必要的情況下可更換有故障的放大器板。<p>狀況二：接通電源，在給定輸入壓力信號后，若壓力變送器輸出過高或過低，且改變輸入壓力信號和調(diào)整零點(diǎn)、量程螺釘時輸出均無反應(yīng)。<p>對于這類故障，除檢查壓力變送器測量部分敏感部件有無異常外，應(yīng)檢查壓力變送器放大器板上“振蕩控制電路部分”工作正常與否。其次檢查放大器板上各運(yùn)算放大器的工作狀況;各部分的元器件有無損壞問題等。此類故障需要更換放大器板。新疆高溫型壓力變送器</p></p><br
