style="text-indent:25px">壓力變送器在電廠中主要用在壓力油罐、壓力氣罐的壓力檢測(cè)，以及集水井的水位壓力的檢測(cè)，變送器一般是將壓力信號(hào)轉(zhuǎn)換為電信號(hào)輸出，通過(guò)計(jì)算輸出信號(hào)可以得出相應(yīng)的壓力值以及水位線。在該領(lǐng)域應(yīng)用時(shí)要滿足保護(hù)系統(tǒng)安全設(shè)計(jì)要求，同時(shí)還必須滿足全數(shù)字化儀控系統(tǒng)的設(shè)計(jì)要求，并考慮電站的運(yùn)行、維護(hù)要求。電站的安全運(yùn)行主要取決于執(zhí)行安全功能的設(shè)備的可靠性。對(duì)于執(zhí)行緊急停堆、應(yīng)急堆芯冷卻、余熱排出、安全殼隔離、安全殼排熱及防止放射性物質(zhì)向環(huán)境釋放這些安全功能的電氣設(shè)備，稱為安全(1E)級(jí)電氣設(shè)備。尤其對(duì)于安裝在電站安全殼內(nèi)的核級(jí)壓力變送器，因工作在有輻照的環(huán)境條件中，并且要求在地震和事故工況下保持其功能與性能，工作條件非常嚴(yán)酷。為使變送器在壽期內(nèi)保證在電站正常運(yùn)行工況或者事故工況下經(jīng)受苛刻的環(huán)境條件執(zhí)行規(guī)定的安全功能，必須使用經(jīng)過(guò)質(zhì)量鑒定合格的壓力變送器產(chǎn)品。用戶在選用壓力變送器時(shí)一定要結(jié)合自己的實(shí)際應(yīng)用情況及其產(chǎn)品特點(diǎn)來(lái)選型，避免盲目選擇。</p><div
