3工作原理
工(gong)作時，高、低(di)壓(ya)(ya)(ya)(ya)側(ce)的隔離膜片(pian)和灌(guan)充液(ye)將過(guo)程壓(ya)(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)(chuan)遞給灌(guan)充液(ye)，接著灌(guan)充液(ye)將壓(ya)(ya)(ya)(ya)力(li)(li)傳(chuan)(chuan)(chuan)(chuan)遞到傳(chuan)(chuan)(chuan)(chuan)感(gan)器(qi)中(zhong)心的傳(chuan)(chuan)(chuan)(chuan)感(gan)膜片(pian)上(shang)。傳(chuan)(chuan)(chuan)(chuan)感(gan)膜片(pian)是個張緊的彈性元(yuan)件，其位(wei)移隨(sui)所受(shou)壓(ya)(ya)(ya)(ya)而變化（對(dui)于GP表(biao)壓(ya)(ya)(ya)(ya)變送(song)器(qi)，大氣壓(ya)(ya)(ya)(ya)如同(tong)施加在傳(chuan)(chuan)(chuan)(chuan)感(gan)膜片(pian)的低(di)壓(ya)(ya)(ya)(ya)側(ce)樣）。AP絕壓(ya)(ya)(ya)(ya)變送(song)器(qi)，低(di)壓(ya)(ya)(ya)(ya)側(ce)始終保持個參(can)考壓(ya)(ya)(ya)(ya)力(li)(li)。傳(chuan)(chuan)(chuan)(chuan)感(gan)膜片(pian)的大位(wei)移量為0.004英寸（0.1毫(hao)米），且(qie)位(wei)移量與壓(ya)(ya)(ya)(ya)力(li)(li)成(cheng)正(zheng)比。兩(liang)側(ce)的電(dian)(dian)容(rong)(rong)板檢測(ce)傳(chuan)(chuan)(chuan)(chuan)感(gan)膜片(pian)的位(wei)置。傳(chuan)(chuan)(chuan)(chuan)感(gan)膜片(pian)和電(dian)(dian)容(rong)(rong)板之間(jian)電(dian)(dian)容(rong)(rong)的差(cha)值被轉換為相應的電(dian)(dian)流，電(dian)(dian)壓(ya)(ya)(ya)(ya)或字HART（高速(su)可(ke)尋址(zhi)遠程發送(song)器(qi)據公路(lu)）輸出信號。
