style="text-indent:25px">當(dāng)前過程變量變送器主要發(fā)展趨勢是無線應(yīng)用、更小的外形尺寸及多變量過程變送器的應(yīng)用。由于有些水泥大集團局部輔助流程已采用了無線技術(shù)，無線變送器也將受到我國水泥行業(yè)的關(guān)注。將無線功能加到過程變量變送器是物有所值，考慮到有些水泥廠占有的物理空間很大，有些工藝測量的位置難于安裝，而有些工藝測量點環(huán)境十分惡劣，用傳統(tǒng)的硬連線安裝器件成本又過高，如果消除過程變量變送器和控制電路之間連接，改用無線通訊能夠節(jié)約能源，減少配線和維護費用，故將無線功能加到過程變量變送器是物有所值。大連傳感器購買用戶在選擇壓力傳感器及變送器時，應(yīng)充分了解壓力測量系統(tǒng)的工況，根據(jù)需要合理選擇。</p><div

style="text-indent:25px">差壓變送器故障調(diào)試步驟；1、查看差壓變送器的電源是否接反了，電源正負極是不是接正確了。2、測量變送器的供電電源，是否有24V直流電壓;必須保證供給變送器的電源電壓≥12V(即變送器電源輸入端電壓≥12V)。如果沒有電源則應(yīng)檢查回路是否斷線、檢測儀表是否選取錯誤(輸入阻抗應(yīng)≤250Ω)等等。3、如果壓力變送器是帶表頭的，需要檢查表頭是否損壞(可以先將表頭的兩根線短路，如果短路后正常，則說明是表頭損壞)，如果是表頭損壞，則需另換表頭。4、如果是差壓壓力變送器出現(xiàn)問題，可將電流表串入24V電源回路中，檢查電流是否正常。如果正常則說明變送器正常，此時應(yīng)檢查回路中其他儀表是否正常。5、電源是否接在變送器電源輸入端，把電源線接在電源接線端口上。</p><p style="text-indent:25px">壓力變送器其測量原理是：流程壓力和參考壓力分別作用于集成硅壓力敏感組件的兩端，其差壓使硅片變形（位移很小，*μm級），以使硅片上用半導(dǎo)體技術(shù)制成的全動態(tài)惠斯登電橋在外部電流源驅(qū)動下輸出正比于壓力的mV級電壓信號。由于硅材料的強性較好，所以輸出信號的線性度及變差指針均很高。工作時，壓力變送器將被測物理量轉(zhuǎn)換成mV級的電壓信號，并送往放大倍數(shù)很高而又可以互相抵消溫度漂移的差動式放大器。放大后的信號經(jīng)電壓電流轉(zhuǎn)換變換成相應(yīng)的電流信號，再經(jīng)過非線性校正，然后產(chǎn)生與輸入壓力成線性對應(yīng)關(guān)系的標(biāo)準(zhǔn)電流電壓信號。傳感器及變送器周圍應(yīng)避免有強電磁干擾。</p><div

style="text-indent:25px">智能差壓變送器的校準(zhǔn):用常規(guī)方法對智能變送器進行校準(zhǔn)是不行的，因為這是由HART變送器結(jié)構(gòu)原理所決定了。因為智能變送器在輸入壓力源和產(chǎn)生的4-20mA電流信號之間，除機械、電路外，還有微處理芯片對輸入數(shù)據(jù)的運算工作，因此調(diào)校與常規(guī)方法有所區(qū)別。實際上廠家對智能變送器的校準(zhǔn)也是有說明的，如ABB的變送器，對校準(zhǔn)就有：“設(shè)定量程”、“重定量程”、“微調(diào)”之分。其中“設(shè)定量程”操作主要是通過LRV、URV的數(shù)字設(shè)定來完成配置工作，而“重定量程"操作則要求將變送器連接到標(biāo)準(zhǔn)壓力源上，通過一系列指令引導(dǎo)，由變送器直接感應(yīng)實際壓力并對數(shù)值進行設(shè)置。而量程的初始、然后設(shè)置直接取決于真實的壓力輸入值。但要看到盡管變送器的模擬輸出與所用的輸入值關(guān)系正確，但過程值的數(shù)字讀數(shù)顯示的數(shù)值會略有不同，這可通過微調(diào)項來進行校準(zhǔn)。一體化溫度變送器具有結(jié)構(gòu)簡單、節(jié)省引線、輸出信號大、工作可靠等優(yōu)點。大連傳感器購買</p><p

style="text-indent:25px">電容式壓力變送器：當(dāng)壓力直接作用在測量膜片的表面，使膜片產(chǎn)生微小的形變，測量膜片上的高精度電路將這個微小的形變變換成為與壓力成正比的高度線性、與激勵電壓也成正比的電壓信號，然后采用**芯片將這個電壓信號轉(zhuǎn)換為工業(yè)標(biāo)準(zhǔn)的4-20mA電流信號或者1-5V電壓信號。由于測量膜片采用標(biāo)準(zhǔn)化集成電路，內(nèi)部包含線性及溫度補償電路，所以可以做到高精度和高穩(wěn)定性，變送電路采用**的兩線制芯片，可以保證輸出兩線制4-20mA電流信號，方便現(xiàn)場接線。溫度傳感器供應(yīng)</p></p><br
