美國(guó)正品UE-J400系列壓力開(kāi)關(guān)UE差壓開(kāi)關(guān)J402-550
UE差壓開(kāi)關(guān)由2個(gè)膜盒腔組成,兩個(gè)腔體分別由兩片密封膜片和一片感差壓膜片密封。高壓和低壓分別進(jìn)入差壓開(kāi)關(guān)的高壓腔和低壓腔,感受到的差壓使感壓膜片形變,通過(guò)欄桿彈簧等機(jī)械結(jié)構(gòu),zui終啟動(dòng)zui上端的微動(dòng)開(kāi)關(guān),使電信號(hào)輸出。差壓開(kāi)關(guān)的感壓元件不同分為膜片和波紋管式,性能特點(diǎn)亦不同。差壓開(kāi)關(guān)由感壓元件的組成不同,原理不同,性能也有不同。膜片式可以做成高靜壓低差壓,而波紋管因?yàn)楸旧砟蛪旱汀?br>技術(shù)參數(shù)
