產品特點：E+H變送器FMR231-AABMJAB4CA結構簡單以機械結構型的器件為主，以彈性元件的形變指示壓力，但這種結構尺寸大、質量重，不能提供電學輸出。隨著半導體技術的發展，半導體壓力傳感器也應運而生。其特點是體積小、質量輕、準確度高、溫度特性好。特別是隨著MEMS技術的發展，半導體傳感器向著微型化發展，而且其功耗小、可靠性高。
E+H變送器FMR231-AABMJAB4CA結構簡單的詳細資料：
E+H變送器一體化(hua)溫度變送器(qi)具有(you)結構簡(jian)單、節(jie)省引線、輸出信號(hao)大(da)、抗干擾能(neng)力(li)強(qiang)、線性好、顯示儀表簡(jian)單、固體模塊抗震(zhen)防(fang)潮、有(you)反接保(bao)護和(he)限流保(bao)護、工作可靠等優點。
一體化溫度變(bian)送器的輸出為統(tong)一的4～20mA信號；可與微(wei)機系(xi)統(tong)或其(qi)它常規儀表匹(pi)配使用。也可應用戶要求做(zuo)成防爆型(xing)或防火(huo)型(xing)測量(liang)儀表。
它是將熱(re)電(dian)(dian)(dian)(dian)(dian)偶產(chan)生的熱(re)電(dian)(dian)(dian)(dian)(dian)勢經冷端補償(chang)放大(da)(da)后，再帽由線(xian)性(xing)電(dian)(dian)(dian)(dian)(dian)路消除熱(re)電(dian)(dian)(dian)(dian)(dian)勢與溫(wen)度(du)的非線(xian)性(xing)誤(wu)差，后放大(da)(da)轉換為(wei)4～20mA電(dian)(dian)(dian)(dian)(dian)流輸出(chu)信(xin)號。為(wei)防(fang)止熱(re)電(dian)(dian)(dian)(dian)(dian)偶測量(liang)中由于(yu)電(dian)(dian)(dian)(dian)(dian)偶斷(duan)絲而使控(kong)溫(wen)失效造成事(shi)故，變送(song)器中還設有斷(duan)電(dian)(dian)(dian)(dian)(dian)保護電(dian)(dian)(dian)(dian)(dian)路。當熱(re)電(dian)(dian)(dian)(dian)(dian)偶斷(duan)絲或接解不良時，變送(song)器會輸出(chu)大(da)(da)值（28mA）以使儀表切斷(duan)電(dian)(dian)(dian)(dian)(dian)源。
E+H變送器主要有電容式E+H壓(ya)(ya)(ya)力變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)和(he)擴(kuo)散(san)硅E+H壓(ya)(ya)(ya)力變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)，陶瓷E+H壓(ya)(ya)(ya)力變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)，應變(bian)(bian)(bian)式E+H壓(ya)(ya)(ya)力變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)等(deng)。E+H壓(ya)(ya)(ya)力變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)根(gen)據測(ce)壓(ya)(ya)(ya)范(fan)圍可分成一般E+H壓(ya)(ya)(ya)力變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)（0.001MPa～35MPa）和(he)微差壓(ya)(ya)(ya)變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)（0～1.5kPa），負壓(ya)(ya)(ya)變(bian)(bian)(bian)送(song)(song)(song)(song)(song)器(qi)三種(zhong)。
E+H壓(ya)力(li)變(bian)送(song)器的(de)主要作用把(ba)壓(ya)力(li)信(xin)(xin)號傳(chuan)到電子設(she)備，進而在計算機顯示壓(ya)力(li)其原理大致是：將水壓(ya)這種壓(ya)力(li)的(de)力(li)學信(xin)(xin)號轉變(bian)成電流（4-20mA）這樣的(de)電子信(xin)(xin)號壓(ya)力(li)和電壓(ya)或電流大小成線性關系，一般是正(zheng)比(bi)關系。
