壓力變送器的精度。在質(zhì)量上分析，壓力變送器的精度是zui重要的技術(shù)參數(shù)。壓力變送器精度關(guān)系到整個測量系統(tǒng)的zui終結(jié)果。儀表的精度簡言之就是儀表測量值接近真值的準確程度，通常用相對百分誤差（也稱相對折合誤差）表示。按儀表工業(yè)規(guī)定，儀表的精確度劃分成若干等級，簡稱精度等級。精度等級的數(shù)字越小，防爆壓力變送器用途，精度越高。我們可以從三個方面理解壓力變送器精度的概念：1、精度表示測量結(jié)果與真值之間的一致程度，它反映測量結(jié)果中系統(tǒng)誤差與隨機誤差的綜合。其定量特征可用測量的不確定度(或極限誤差)來表示，防爆壓力變送器用途。2、精度表示在一定條件下進行多次測量時，所得測量結(jié)果彼此之間符合的程度，它反映測量結(jié)果中隨機誤差的影響程度。3、精度表示測量結(jié)果中系統(tǒng)誤差大小的程度，防爆壓力變送器用途，反映了規(guī)定條件下，測量結(jié)果中所有系統(tǒng)誤差的綜合。在價格上，壓力變送器的精度越高，其價格也越昂貴。在實際使用過程中，如果測量目的是定性分析，不必要選用juedui量值精度高的壓力變送器；如果是為了定量分析，必須獲得精確的測量值，就需選用精度等級能滿足要求的壓力變送器。擴散硅壓力變送器可替代傳統(tǒng)的遠傳壓力表，霍爾元件、差動變送器，并具有DDZ-Ⅱ及DDZ-Ⅲ型變送器性能。防爆壓力變送器用途</p><div

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)展細分化的需求。不同類型的壓力變送器不僅在特點上有差異，在注意事項上也是有一定的區(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。 </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)致測量誤差不準確，如膜片損壞壓力變送器則無法使用。 </p>小巧型壓力變送器是被測介質(zhì)的壓力直接作用于傳感器的膜片上(不銹鋼或陶瓷)，使膜片產(chǎn)生與介質(zhì)壓力成正比的微位移，使傳感器的電阻值發(fā)生變化，和用電子線路檢測這一變化，并轉(zhuǎn)換輸出一個對應(yīng)于這一壓力的標準測量信號。 <p> 小巧型壓力變送器的產(chǎn)品類型:1、擴散硅壓力變送器2、陶瓷壓力變送器。 </p> <p> 小巧型壓力變送器產(chǎn)品特點：可調(diào)節(jié)；工作穩(wěn)定可靠；抗振動、抗沖擊；反極性、過電壓保護；防電磁射頻干擾。 </p> <p> 小巧型壓力變送器的技術(shù)參數(shù)：測量范圍:-100KPa~60MPa允許溫度介質(zhì)溫度:-30~85℃比較高可達200℃環(huán)境溫度:-30~80℃儲存溫度:-30~+80℃溫度影響:TK<±0.02±%FS/K精度等級:0.2、0.5級工作電壓:12~36VDC工作溫度:-30~80℃輸出信號:4~20mA(二線制)、1~5V(三線制)負載電阻:<=750Ω。壓力變送器的靈敏度高，與被測量無關(guān)的外界噪聲也容易混入，也會被放大系統(tǒng)放大，影響測量精度。</p><div

通用型壓力變送器采用壓阻式壓力傳感器。壓阻式傳感器是壓力式傳感器的一種。壓阻式壓力傳感器又稱擴散硅壓力傳感器。壓阻式壓力變送器,傳感器信號經(jīng)過信號處理電路后轉(zhuǎn)換為標準信號輸出，產(chǎn)品經(jīng)過了長期老化及穩(wěn)定性考核等工藝嚴格篩選，性能穩(wěn)定可靠。應(yīng)用于環(huán)境比較惡劣的露天現(xiàn)場，同時要求能夠現(xiàn)場觀測壓力顯示、需要零點遷移和量程調(diào)節(jié)的場合。應(yīng)用領(lǐng)域：適用于石油、化工、冶金、電力、輕工、紡織、建材、水文地質(zhì)、食品、醫(yī)藥、環(huán)境控制等行業(yè)的過程控制和壓力測量。 </p> <p> 水壓變送器擴散硅跟電容變送器的對比:根本區(qū)別在于基礎(chǔ)檢出信號不同。以及相應(yīng)的電路和構(gòu)造不同;電容式變送器的基礎(chǔ)信號是電容量；擴散硅變送器的基礎(chǔ)信號是電阻值;電容式在壓力作用下敏感元件的膜片發(fā)生位移，導(dǎo)致膜片與相鄰電極構(gòu)成的電容量發(fā)生變化而檢出壓力；擴散硅在壓力作用下敏感元件的膜片發(fā)生位移，產(chǎn)生的力作用在擴散硅材料商，使擴散硅的阻值變化而檢出壓力;電容式利用的是物理性質(zhì)，所以主要受制造水平的限制；擴散硅利用的是材料的物理性質(zhì)，所以受材料影響較大;擴散硅在體積、價格上有優(yōu)勢；但受擴散硅材料的穩(wěn)定性影響，壽命的精度較差。從精度角度來分類，因為我國國標的精度就為0.5%.　所以近年來又可以分為高精度壓力變送器和一般壓力變送器。陜西經(jīng)濟型壓力變送器推薦廠家</p><p style="text-indent:25px">電流輸出是壓力變送器常用的一種信號輸出方式，這與它的性能特點有關(guān)。防爆壓力變送器用途</p><p> 壓力變送器的供電電壓： </p> <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，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， 24V DC能夠適應(yīng)大多數(shù)傳輸和負載需求（帶 250Ω×2個負載和 1KM 傳輸距離），高了浪費低了應(yīng)用受限制，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 /> 防爆壓力變送器用途</p><p
