style="text-indent:25px">壓力變送器是指以輸出為標(biāo)準(zhǔn)信號(hào)的壓力傳感器，是一種接受壓力變量按比例轉(zhuǎn)換為標(biāo)準(zhǔn)輸出信號(hào)的儀表。它能將測(cè)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(biāo)準(zhǔn)的電信號(hào)（如4~20mADC等），以供給指示報(bào)警儀、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測(cè)量、指示和過(guò)程調(diào)節(jié)。壓力變送器是工業(yè)實(shí)踐中較為常用的一種傳感器，其普遍應(yīng)用于各種工業(yè)自控環(huán)境，涉及水利水電、鐵路交通、智能建筑、生產(chǎn)自控、航空航天、**、石化、油井、電力、船舶、機(jī)床、管道等眾多行業(yè)。上海變送器單價(jià)變送器遵循一個(gè)物理定律（或?qū)嶒?yàn)數(shù)學(xué)模型）將物理量的變化轉(zhuǎn)化成4-20mA等標(biāo)準(zhǔn)信號(hào)的裝置。</p><div

style="text-indent:25px">變送器常見(jiàn)故障：（1）安裝時(shí)應(yīng)使變送器的壓力敏感件軸向垂直于重力方向，如果安裝條件限制，則應(yīng)安裝固定后調(diào)整變送器零位到標(biāo)準(zhǔn)值。（2）殘存的壓力釋放不出，因此傳感器零位又下不來(lái)。排除此原因的較好的方法是將傳感器卸下，直接察看零位是否正常，如果正常更換密封圈再試。（3）加壓變送器輸出不變化，再加壓變送器輸出突然變化，泄壓變送器零位回不去。產(chǎn)生此現(xiàn)象的原因極有可能是壓力傳感器密封圈引起的。（4）是否符合供電要求；電源與變送器及負(fù)載設(shè)備之間有無(wú)接線錯(cuò)誤。如果變送器接線端子上無(wú)電壓或極性接反均可造成變送器無(wú)電壓信號(hào)輸出。</p><p 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(fù)極是不是接正確了。2、測(cè)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(méi)有電源則應(yīng)檢查回路是否斷線、檢測(cè)儀表是否選取錯(cuò)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(shuō)明是表頭損壞)，如果是表頭損壞，則需另?yè)Q表頭。4、如果是差壓壓力變送器出現(xiàn)問(wèn)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(shuō)明變送器正常，此時(shí)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。變送器的種類很多，按工作能源分，有氣動(dòng)變送器、電動(dòng)變送器。</p><div
