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行排查呢？ </p> <p> 1、根據(jù)控制室趨勢圖進行分析故障原因，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，首先對其進行斷電，而后在送電進行觀察，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行比較，并確認測量管道是否有余壓。4、對差壓變送器進行一次到兩次機械零點調(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> 哪些方法能夠避免壓力變送器損壞: </p> <p> 壓力變送器剛買回來使用，效果很好，可沒幾天就不能用了。其實壓力變送器在使用過程中，如果方法不當，是會造成損壞的。壓力變送器的損壞，會對用戶造成很大的影響。接下來教大家如何正確使用壓力變送器避免其損壞。希望能夠幫助到大家。 </p> <p> 1：在壓力傳輸過程中，應(yīng)注意壓力變送器與散熱管連接處，切勿漏氣。管路中必須保持暢通，管道中的沉積物，極有可能損壞壓力變送器膜片。開始使用前如果閥門是關(guān)閉的，則使用時應(yīng)該非常小心緩慢地打開閥門，以免被測介質(zhì)直接沖擊壓力變送器膜片從而損壞膜片。2：測量蒸汽或其他高溫介質(zhì)時，應(yīng)使用散熱管。溫度不得超過壓力變送器使用溫度的極限。3：切勿用硬物碰觸膜片，導(dǎo)致壓力變送器隔離膜片損壞。4：被測介質(zhì)不允許結(jié)冰，否則將損傷壓力變送器元件，導(dǎo)致變送器損壞，必要時需對壓力變送器進行溫度保護，以防結(jié)冰。5：切勿用高于36V電壓加到壓力變送器上，導(dǎo)致變送器損壞。還有，在使用安裝壓力變送器前，一定要仔細認真閱讀說明書。多方位了解壓力變送器的各項信息。保證在合理合規(guī)的前提下，對壓力變送器進行操作。壓力變送器的外殼是否有效、真實的接地。壓力變送器外殼有效接地，具有很好的抗干擾作用。</p><div

壓力變送器常用選用方法壓力變送器的輸出信號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)場的使用要求，選型時有幾點需要注意的地方： </p> <p> 1、測量壓力的類型: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，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，高于肯定壓力零位的壓力；差壓是指兩個壓力之間的差值。 </p> <p> 2、準確度等級:變送器的測量誤差錯按精度等級來劃分，實際使用過程中，依據(jù)測量誤差的需求并本著適用經(jīng)濟的原則進行挑選。 </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極限，否則會影響商品的運用壽命乃至損壞商品。2倍丈量規(guī)模的過載維護是我公司商品的規(guī)范裝備（也可依據(jù)客戶請求進行定制）。 </p> <p> 4、測量范圍:一般按實際測量壓力為測量范圍的80%挑選。 </p> <p> <br /> 它能將測壓元件傳感器感受到的氣體、液體等物理壓力參數(shù)轉(zhuǎn)變成標準的電信號。陜西恒壓供水壓力變送器特點</p><p style="text-indent:25px">早期的壓力變送器大多數(shù)采用電壓輸出信號，即將測量信號轉(zhuǎn)換為0～10VDC、0.5～2.5VDC等電壓輸出。陜西恒壓供水壓力變送器特點</p><p> 壓力變送器的氣體壓力測量： </p> <p> 一般壓力變送器的適用于測量氣體、液體等與變送器材質(zhì)兼容的介質(zhì)。壓力變送器是如何測量氣體介質(zhì)的。壓力變送器對于氣體可進行絕壓、負壓和表壓的測量。氣體的壓力簡單的說就是氣體本身對于容器壁的壓力。很多物理和化學(xué)特性都與壓力有關(guān)，比如氣體的沸點、熔點和蒸氣壓，熱力學(xué)，動力學(xué)等。所以說壓力變送器對于壓力氣體的測量是具有重要意義的。在壓力變送器的單晶硅片上擴散一個惠斯通電橋，當管道或者容器內(nèi)的氣體對壓力變送器進行施壓，使得壓力變送器橋壁電阻值發(fā)生變化（壓阻效應(yīng)），這樣就產(chǎn)生一個差動電壓信號，這個信號在經(jīng)過**的放大器，終將測得的量程相對應(yīng)的信號轉(zhuǎn)化成標準的電流、電壓或者數(shù)字信號。這就是壓力變送器如何對氣體進行測量的一個過程。壓力變送器對于氣體的測量尤其是蒸汽或其他高溫氣體進行測量的時候，需要注意不要讓高溫氣體的溫度超過壓力變送器的工作溫度范圍，必要時，為壓力變送器添加冷卻裝置是個不錯的選擇。
