常用壓力傳感器四種常見的故障

　　一、壓力上去
，變送器輸也上不去

　　此ci種zhong情qing況kuang
，先xian應ying檢jian查zha壓ya力li接jie口kou是shi否fou漏lou氣qi或huo者zhe被bei堵du住zhu，如ru果guo確que認ren不bu是shi
，檢jian查zha接jie線xian方fang式shi和he檢jian查zha電dian源yuan，如ru電dian源yuan正zheng常chang則ze進jin行xing簡jian單dan加jia壓ya看kan輸shu出chu是shi否fou變bian化hua，或huo者zhe察cha看kan傳chuan感gan器qi零ling位wei是shi否fou有you輸shu出chu
，若ruo無wu變bian化hua則ze傳chuan感gan器qi已yi損sun壞huai，可ke能neng是shi儀yi表biao損sun壞huai或huo者zhe整zheng個ge係xi統tong的de其qi他ta環huan節jie的de問wen題ti

　　三
、變送器輸出信號不穩

　　這種故障有肯是壓力源的問題。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

；

　　四、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；最zui後hou一yi種zhong易yi出chu現xian的de故gu障zhang是shi微wei差cha壓ya變bian送song器qi安an裝zhuang位wei置zhi對dui零ling位wei輸shu出chu的de影ying響xiang。微wei差cha壓ya變bian送song器qi由you於yu其qi測ce量liang範fan圍wei很hen小xiao
，變bian送song器qi中zhong傳chuan感gan元yuan件jian會hui影ying響xiang到dao微wei差cha壓ya變bian送song器qi的de輸shu出chu。安an裝zhuang時shi應ying使shi變bian送song器qi的de壓ya力li敏min感gan件jian軸zhou向xiang垂chui直zhi於yu重zhong力li方fang向xiang，安an裝zhuang固gu定ding後hou調tiao整zheng變bian送song器qi零ling位wei到dao標biao準zhun值zhi。

　　上shang述shu的de內nei容rong就jiu是shi常chang用yong壓ya力li傳chuan感gan器qi四si種zhong常chang見jian的de故gu障zhang，我wo們men通tong常chang使shi用yong的de壓ya力li傳chuan感gan器qi主zhu要yao是shi利li用yong壓ya電dian效xiao應ying製zhi造zao而er成cheng的de，所suo以yi說shuo常chang用yong壓ya力li傳chuan感gan器qi也ye稱cheng為wei壓ya電dian傳chuan感gan器qi。
