      差(cha)壓(ya)變(bian)送(song)器用於(yu)測量(liang)液體(ti)、氣體(ti)或(huo)蒸汽(qi)的壓(ya)力(li)、液位(wei)或(huo)密(mi)度。采用單(dan)晶矽差(cha)壓(ya)敏(min)感(gan)元件或(huo)全密封(feng)電(dian)容，使壓(ya)力(li)測量(liang)有(you)很高測量(liang)精度的同(tong)時保(bao)證了(le)優(you)良(liang)的(de)穩定(ding)性(xing)和可(ke)靠(kao)性(xing)，該壓(ya)力(li)經毛細(xi)管(guan)內(nei)的灌(guan)充(chong)矽油(或(huo)其它的液體(ti))傳遞至(zhi)變送(song)器的(de)主(zhu)體(ti)，然後由變送(song)器主(zhu)體(ti)內(nei)的δ室和放(fang)大(da)線(xian)路(lu)板，將壓(ya)力(li)或(huo)差(cha)壓(ya)轉換4～20mA DC信號輸(shu)出。1151差(cha)壓(ya)變(bian)送(song)器廠(chang)家

       差(cha)壓(ya)變(bian)送(song)器可(ke)配(pei)置HART通訊協議，可(ke)與(yu)控(kong)制系(xi)統(tong)或(huo)手操器相(xiang)互通(tong)訊，通過(guo)它們進行設定(ding)、監(jian)控(kong)、測試和(he)組(zu)態。HART協(xie)議使用工業標(biao)準(zhun)的(de)BELL202頻率相(xiang)移(yi)鍵(jian)控(kong)（FSK）技(ji)術，以數字(zi)信(xin)號疊(die)加(jia)在(zai)4-20mA的(de)信號上實現通(tong)訊，通訊時頻率信號對4-20mA不(bu)產(chan)生(sheng)幹擾(rao)。1151差(cha)壓(ya)變(bian)送(song)器廠(chang)家
