    隔ge離li型xing壓ya力li變bian送song器qi主zhu要yao是shi針zhen對dui特te殊shu的de被bei測ce量liang介jie質zhi使shi用yong的de

，如ru被bei測ce介jie質zhi離li開kai設she備bei後hou會hui產chan生sheng結jie晶jing，而er使shi用yong普pu通tong型xing變bian送song器qi需xu要yao取qu出chu介jie質zhi，會hui將jiang導dao壓ya管guan和he膜mo盒he室shi堵du塞sai使shi其qi不bu能neng正zheng常chang工gong作zuo，所suo以yi必bi須xu選xuan用yong隔ge離li型xing。隔ge離li型xing通tong常chang作zuo成cheng法fa蘭lan式shi安an裝zhuang，即ji在zai被bei測ce設she備bei上shang開kai口kou加jia法fa蘭lan使shi變bian送song器qi安an裝zhuang後hou它ta的de感gan應ying膜mo片pian是shi設she備bei壁bi的de一yi部bu分fen，這zhe樣yang它ta不bu會hui取qu出chu被bei測ce介jie質zhi
，一yi般ban不bu會hui造zao成cheng結jie晶jing堵du塞sai。

    如ru果guo被bei測ce介jie質zhi需xu求qiu結jie晶jing溫wen度du較jiao高gao時shi，可ke選xuan用yong將jiang膜mo片pian凸tu出chu結jie構gou的de壓ya力li變bian送song器qi，這zhe樣yang可ke將jiang傳chuan感gan膜mo片pian插cha入ru到dao設she備bei內nei部bu，從cong而er感gan應ying到dao的de介jie質zhi溫wen度du不bu會hui降jiang低di
，這zhe樣yang測ce量liang是shi有you保bao障zhang的de，即ji選xuan用yong插cha入ru式shi法fa蘭lan壓ya力li變bian送song器qi。

    然而，隔離型壓力變送器有遠傳型和一體型。通常所說的遠傳型即外膜盒與測量膜盒之間用加強毛細管連接，一般毛細管為3~5米，這樣外膜盒裝在設備上

，內膜盒及變送器可以安裝在便於維護的支架上；另ling一yi種zhong形xing式shi是shi外wai膜mo盒he與yu變bian送song器qi作zuo成cheng一yi體ti直zhi接jie由you法fa蘭lan安an裝zhuang在zai設she備bei上shang。對dui於yu隔ge離li型xing壓ya力li變bian送song器qi它ta還hai可ke以yi作zuo成cheng螺luo紋wen連lian接jie型xing，即ji外wai膜mo盒he或huo外wai彈dan性xing元yuan件jian可ke在zai安an裝zhuang螺luo紋wen的de前qian麵mian
，隻zhi要yao在zai被bei測ce設she備bei上shang焊han接jie上shang內nei螺luo紋wen凸tu台tai，便bian可ke將jiang變bian送song器qi直zhi接jie擰ning到dao設she備bei上shang

，安an裝zhuang非fei常chang方fang便bian。

    通過以上的介紹，我們了解到了隔離型壓力變送器的製作複雜，而且材質要求頗高
，這也就導致了其價格要高於普通型的3倍左右。
