差壓變送器是有固定量程范圍的，在量程范圍內(nèi)使用，差壓變送器性能才是正常的。在現(xiàn)場使用過程中，如果出現(xiàn)超量程的現(xiàn)象。這時候要怎么對差壓變送器進(jìn)行排查呢？ </p> <p> 1、根據(jù)控制室趨勢圖進(jìn)行分析故障原因，排查是否因工藝原因造成的壓力值偏差，誤判斷為儀表問題。如果為工藝原因，趨勢指示與壓力示值程緩慢變化趨勢，或根據(jù)工況有規(guī)律變化，如果是儀表問題，一般趨勢圖不程緩慢變化，變化幅度非常劇烈。2、如處理故障為超量程，首先對其進(jìn)行斷電，而后在送電進(jìn)行觀察，如果故障顯示仍然為超量程，那么測量一下電流值是否對應(yīng)其指示壓力值。3、參照比較差壓變送器現(xiàn)場顯示壓力，與就地指示壓力表顯示的壓力值進(jìn)行比較，并確認(rèn)測量管道是否有余壓。4、對差壓變送器進(jìn)行一次到兩次機(jī)械零點(diǎn)調(diào)整，故障仍然顯示為超量程，那么就要考慮是否為儀表本身的故障。5、差壓變送器自身故障情況分為兩種。情況一：變送器3大模塊有故障，情況二：變送器感壓膜片變形。6、如果差壓變送器在更換模塊后故障仍為超量程，那么終情況即為差壓變送器感壓膜片變形或者損壞。 </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(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， 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，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 /> 壓力變送器是一種接受壓力變量,經(jīng)傳感轉(zhuǎn)換后,將壓力變化量按一定比例轉(zhuǎn)換為標(biāo)準(zhǔn)輸出信號的儀表。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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(zhǔn)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，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(jī)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。2、精度表示在一定條件下進(jìn)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(jī)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，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(shí)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。壓力變送器的殼體、過程連接與膜片采用的都是不銹鋼材質(zhì)，測量介質(zhì)要與304、316不銹鋼兼容。陜西煙塵治理壓力變送器性能</p><p

在壓力變送器購買與應(yīng)用時，有多種多樣的技術(shù)參數(shù)需要我們了解。如果忽略了其中的一些信息，很容易造成壓力變送器的損壞。像是，壓力變送器應(yīng)用的管路溫度過高，而壓力變送器的實(shí)際使用溫度范圍在-40～80℃，如果我們對壓力變送器的使用溫度范圍有了解，會在現(xiàn)場工況中添加緩沖管，用于散熱，防止高溫對壓力變送器進(jìn)行沖擊，確保壓力變送器的使用壽命。通常情況下壓力變送器會有兩個溫度段的標(biāo)定。其中一個溫度段是正常工作溫度，另外一個是溫度補(bǔ)償范圍。正常工作溫度范圍是指變送器在工作狀態(tài)下，不被破壞的時候的溫度范圍，在超出溫度補(bǔ)償范圍時可能會達(dá)不到其應(yīng)有的性能指標(biāo)。溫度補(bǔ)償范圍是一個比工作溫度范圍小的典型范圍。在這個范圍內(nèi)工作變送器肯定會達(dá)到其應(yīng)有的性能指標(biāo)。
