MBC壓力開關(guān)適用于那些需要著重考慮空間和可靠性要求的海上應(yīng)用。MBC壓力開關(guān)具有緊湊的結(jié)構(gòu)，并且基于我們最新的模塊式設(shè)計，它們可以抵抗船舶機械艙中的各種惡劣工況。MBC具有高度抗振性能，并且通過了所有的常見的船級認證�；夭罟潭�，但很小，可以保證對關(guān)鍵壓力的精確監(jiān)視。
?壓力范圍：-0.2到400bar
?低回差（固定）微型開關(guān) 
?防護等級IP65堅固耐用，抗海水侵蝕 
?結(jié)構(gòu)緊湊可靠
?抗沖擊、抗振動
?膜片式針對脈動特性的應(yīng)用 
?針對壓力峰值和介質(zhì)為海水的應(yīng)用
?安裝成本低 
?可提供壓差開關(guān)
?易于安裝到測試閥塊上
