概述
壓ya力li傳chuan感gan器qi是shi能neng感gan受shou壓ya力li信xin號hao，並bing能neng按an照zhao一yi定ding的de規gui律lv將jiang壓ya力li信xin號hao轉zhuan換huan成cheng可ke用yong的de輸shu出chu的de電dian信xin號hao的de器qi件jian或huo裝zhuang置zhi。壓ya力li傳chuan感gan器qi通tong常chang由you壓ya力li敏min感gan元yuan件jian和he信xin號hao處chu理li單dan元yuan組zu成cheng。按an不bu同tong的de測ce試shi壓ya力li類lei型xing，壓ya力li傳chuan感gan器qi可ke分fen為wei表biao壓ya傳chuan感gan器qi、差壓傳感器和絕壓傳感器。
應用
壓力傳感器是工業實踐中最為常用的一種傳感器，其廣泛應用於各種工業自控環境，涉及水利水電、鐵路交通、智能建築、生產自控、航空航天、軍工、石化、油井、電力、船舶、機床、管道等眾多行業。
常見問題
1.密封圈的問題

2.變送器與指針式壓力表對照偏差大
出現偏差是正常的現象，確認正常的偏差範圍即可；
3.微差壓變送器安裝位置對零位輸出的影響。

5. 變送器輸出信號不穩
這種故障有可能是壓力源的問題。壓力源本身是一個不穩定的壓力，很有可能是儀表或壓力傳感器抗幹擾能力不強、傳感器本身振動很厲害和傳感器故障；
