UE防爆壓力開關(guān)工作原理
UE防爆壓力開關(guān)產(chǎn)品工作原理:
UE防爆壓力開關(guān)是通過堅固的密封殼體將接線觸點密閉在堅固空間中達到隔爆的效果。
UE防爆壓力開關(guān)工作原理為純機械形變導(dǎo)致微動開關(guān)動作,。當(dāng)壓力增加時,作用在不同的傳感壓力元器件(膜片,、波紋管,、活塞)產(chǎn)生形變,,將向上移動,通過欄桿彈簧等機械結(jié)構(gòu),,zui終啟動zui上端的微動開關(guān),,使電信號輸出,,設(shè)定方式從功能原理上又分成連續(xù)位移型和力平衡型。防爆壓力開關(guān)按原理可分為機械防爆壓力開關(guān)和電子防爆壓力開關(guān),,機械式中又分為普通的和密封型.
