EJA110A-DMS4A-92DA橫河儀川差壓變送器
壓力變送器和差壓變送器單從名詞上講測量的是壓力和兩個壓力的差，但它們間接測量的參數(shù)是有很多的,。如壓力變送器，除測量壓力外,，它還可以測量設(shè)備內(nèi)的液位,。在常壓容器測量液位時，需用一臺壓變即可,。當測量受壓容器液位時,，可用兩臺壓變,，即測量下限一臺，測量上限一臺,，它們的輸出信號可進行減法運算,，即可測出液位，一般選用差壓變送器,。在容器內(nèi)液位與壓力值不變

詳細介紹

EJA110A-DMS4A-92DA橫河儀川差壓變送器

橫河儀川壓力變送器特點：壓力變送器也稱差變送器,，主要由測壓元件傳感器、模塊電路,、顯示表頭,、表殼和過程連接件等組成,。它能將接收的氣體,、液體等壓力信號轉(zhuǎn)變成標準的電流電壓信號，以供給指示報警儀,、記錄儀,、調(diào)節(jié)器等二次儀表進行測量、指示和過程調(diào)節(jié),。
壓力變送器測量原理是：流程壓力和參考壓力分別作
變送器用于集成硅壓力敏感元件的兩端,，其差壓使硅片變形（位移很小，僅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，所以輸出信號的線性度及變差指標均很高,。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，zui后產(chǎn)生與輸入壓力成線性對應(yīng)關(guān)系的標準電流電壓信號,。

橫河儀川一體化溫度變送器：一體化溫度變送器一般由測溫探頭（熱電偶或熱電阻傳感器）和兩線制固體電子單元組成,。采用固體模塊形式將測溫探頭直接安裝在接線盒內(nèi)，從而形成一體化的變送器,。一體化溫度變送器一般分為熱電阻和熱電偶型兩種類型,。

熱電阻溫度變送器是由基準單元、R/V轉(zhuǎn)換單元,、線性電路,、
變送器反接保護、限流保護,、V/I轉(zhuǎn)換單元等組成,。測溫熱電阻信號轉(zhuǎn)換放大后，再由線性電路對溫度與電阻的非線性關(guān)系進行補償，經(jīng)V/I轉(zhuǎn)換電路后輸出一個與被測溫度成線性關(guān)系的4～20mA的恒流信號,。
熱電偶溫度變送器一般由基準源,、冷端補償、放大單元,、線性化處理,、V/I轉(zhuǎn)換、斷偶處理,、反接保護,、限流保護等電路單元組成。它是將熱電偶產(chǎn)生的熱電勢經(jīng)冷端補償放大后,，再帽由線性電路消除熱電勢與溫度的非線性誤差,，zui后放大轉(zhuǎn)換為4～20mA電流輸出信號。為防止熱電偶測量中由于電偶斷絲而使控溫失效造成事故,，變送器中還設(shè)有斷電保護電路,。當熱電偶斷絲或接解不良時，變送器會輸出zui大值（28mA）以使儀表切斷電源,。
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,、抗干擾能力強,、線性好、顯示儀表簡單,、固體模塊抗震防潮,、有反接保護和限流保護、工作可靠等優(yōu)點,。
一體化溫度變送器的輸出為統(tǒng)一的4～20mA信號,；可與微機系統(tǒng)或其它常規(guī)儀表匹配使用。也可用戶要求做成防爆型或防火型測量儀表,。
