壓(ya)(ya)(ya)力(li)(li)(li)變送器(qi)(qi)(qi)(qi)是工業實踐中常用(yong)(yong)的(de)一種傳感器(qi)(qi)(qi)(qi)，其廣泛應(ying)用(yong)(yong)于(yu)各種工業自控環境，涉及水(shui)利(li)水(shui)電、鐵路交通、智能建筑、生產自控、航空航天、軍工、石化、油井、電力(li)(li)(li)、船舶、機床(chuang)、管道(dao)等眾多行業。下面就簡單介紹一些常用(yong)(yong)壓(ya)(ya)(ya)力(li)(li)(li)變送器(qi)(qi)(qi)(qi)的(de)原理及其應(ying)用(yong)(yong)、壓(ya)(ya)(ya)力(li)(li)(li)變送器(qi)(qi)(qi)(qi)是用(yong)(yong)于(yu)測量液(ye)體、氣體或蒸汽的(de)液(ye)位、密度和壓(ya)(ya)(ya)力(li)(li)(li)，然后將壓(ya)(ya)(ya)力(li)(li)(li)信號轉變成4～20mADC信號輸出。

壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器主(zhu)要有(you)電容式(shi)壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器和擴散硅壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器，陶瓷壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器，應變(bian)(bian)(bian)式(shi)壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器等(deng)。壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器根據(ju)測壓(ya)(ya)(ya)(ya)范圍可分成一般壓(ya)(ya)(ya)(ya)力(li)變(bian)(bian)(bian)送(song)器（0.001MPa～35MPa）和微差壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)送(song)器（0～1.5kPa），負壓(ya)(ya)(ya)(ya)變(bian)(bian)(bian)送(song)器三種。
