哪些壓力開關可適用在危險場合
一、防爆型機械壓力開關
防爆型機械壓力開關是純機械的開關工作，它的工作原理是當被測介質的壓力增加或減小時，使測壓原件伸長或縮短彈性元件，再通過杠桿推動開關觸點使其閉合或斷開，從而達到對介質壓力控制的目的。防爆型機械壓力開關是在純機械開關的基礎上添加了防爆功能，可以在石油化工設備或礦井中使用。
二、防爆型智能壓力開關
防爆型智能壓力開關不僅是防爆機械壓力開關的升級，同時也是智能壓力開關的衍生產品，該系列開關輸出的信號類型為電信號，在智能壓力開關的基礎上增加了密封性能超群的外殼，不僅密封性能良好，同時還擁有著良好的防爆性能，為鍋爐、石化、機械、冶金等行業帶來了極大的便利與安全。
