bellows）作為感受壓力的敏感元件的壓力計，這是一種彈性式壓力計。波紋管又稱皺紋箱，它是一種表面上有許多同心環(huán)狀波形皺紋的薄壁圓管。當波紋管作為壓力敏感元件時，將波紋管開口的一端連接于固定的基座上，壓力由此傳至管內。在壓力的作用下，波紋管伸長或收縮一直到壓力與彈性力平衡為止。這時管的自由端就產生一定位移，通過傳動放大機構后，使指針轉動顯示讀數(shù)。波紋管自由端的位移與所測壓力成正比。波紋管可以分成單層和多層。在總厚度相同的條件下，多層波紋管的內部應力小，能承受更高的壓力，耐久性也有所增加。在壓力或軸向力的作用下，波紋管將伸長或縮短，由于它在軸向容易變形，所以靈敏度較高。波紋管對于低壓力（3000Pa~0.5MPa）比彈簧管和膜片靈敏，而且所能產生用以轉動指針或記錄筆的力也比較大。增加了彈簧后的多層波紋管的測壓范圍可以達到7MPa（可測量壓水堆核電廠二次側蒸汽的壓力）。西安超高溫差壓遠傳變送器帶傳感器的變送器通常由兩部分組成：傳感器和信號轉換器。</p><div

style="text-indent:25px">熱電阻溫度變送器由基準單元、R/V轉換單元、線性電路、反接保護、限流保護、V/I轉換單元等組成。測溫熱電阻信號轉換放大后，再由線性電路對溫度與電阻的非線性關系進行補償，經V/I轉換電路后輸出一個與被測溫度成線性關系的4～20mA的恒流信號。熱電阻溫度變送器的結構大體上可分為三大部分：輸入電橋、放大電路及反饋電路。其輸入電橋實質上是一個不平衡電橋。熱電阻被接入其中一個橋臂，當受溫度變化引起熱電電阻阻值發(fā)生改變后，電橋就輸出一個不平衡電壓信號，此電壓信號通過放大電路和反饋電路，便可以得到一個與輸入信號呈線性函數(shù)關系的輸出電流。</p><p style="text-indent:25px">智能遠傳差壓變送器通常也叫雙法蘭差壓變送器。差壓變送器與被測設備之間用毛細管連接。當差壓變送器與被測設備之間用毛細管連接即成為帶遠傳差壓變送器，是一種通過安裝在管道或容器上的遠傳裝置來感受被測壓力，該壓力經毛細管內的灌充硅油(或其它的液體)傳遞至變送器的主體，然后由變送器主體內的δ室和放大線路板，將壓力或差壓轉換4～20mA.DC信號輸出，與符合HART協(xié)議的手操器配合,可以相互通訊，進行設定和監(jiān)控。為了適應不同的需求，DP智能遠傳差壓變送器具有多種形式的遠傳裝置方式，主體結構與差壓變送器相同，普遍應用于石油、化工、電力、食品、造紙、市政工程等行業(yè)。pt100溫度傳感器主要用于工業(yè)過程溫度參數(shù)的測量和控制。</p><div

style="text-indent:25px">隔離器是一種采用線性光耦隔離原理，將輸入信號進行轉換輸出。輸入，輸出和工作電源三者相互隔離，特別適合與需要電隔離的設備儀表配用。隔離器又名信號隔離器，是工業(yè)控制系統(tǒng)中重要組成部分。在工業(yè)生產過程中實現(xiàn)監(jiān)視和控制需要用到各種自動化儀表、控制系統(tǒng)和執(zhí)行機構，它們之間的信號傳輸既有微弱到毫伏級、微安級的小信號，又有幾十伏，甚至數(shù)千伏、數(shù)百安培的大信號；既有低頻直流信號，也有高頻脈沖信號等等，構成系統(tǒng)后往往發(fā)現(xiàn)在儀表和設備之間信號傳輸互相干擾，造成系統(tǒng)不穩(wěn)定甚至誤操作。出現(xiàn)這種情況除了每個儀表、設備本身的性能原因如抗電磁干擾影響外，還有一個十分重要的因素就是由于儀表和設備之間的信號參考點之間存在電勢差，因而形成“接地環(huán)路”造成信號傳輸過程中失真。因此，要保證系統(tǒng)穩(wěn)定和可靠的運行，“接地環(huán)路”問題是在系統(tǒng)信號處理過程中必須解決的問題。溫度變送器技術已經非常成熟了，在各工廠中非常常見。進口差壓液位變送器價位</p><p
