PT211船用壓力變送器選(xuan)用(yong)進(jin)口壓(ya)(ya)力(li)芯(xin)片，敏感(gan)元(yuan)件(jian)采用(yong)擴散(san)或離子注入等工藝(yi)形成電(dian)(dian)阻(zu)并連(lian)接成惠斯通電(dian)(dian)橋(qiao)(qiao)，用(yong)微機械(xie)加(jia)工技(ji)術在電(dian)(dian)橋(qiao)(qiao)下形成壓(ya)(ya)力(li)敏感(gan)膜片。當壓(ya)(ya)力(li)作(zuo)用(yong)在膜片上(shang)(shang)時，電(dian)(dian)阻(zu)值(zhi)發生變化(hua)并且產生一 個(ge)與作(zuo)用(yong)壓(ya)(ya)力(li)成正比的線性(xing)化(hua)輸出(chu)信號。我們在惠斯通電(dian)(dian)橋(qiao)(qiao)上(shang)(shang)加(jia)上(shang)(shang)直(zhi)流(liu)電(dian)(dian)源，就會產生一個(ge)直(zhi)流(liu)電(dian)(dian)壓(ya)(ya)信號的輸出(chu)。經過二次轉換(huan)線路，實現兩線制4～20MA輸出(chu)。
