壓力開關的分類介紹
目前市面上的壓力開關主要有：機械式壓力開關，智能壓力開關，隔爆型壓力開關。今天我們就這幾種壓力開關來簡單了解下，以便于后期客戶朋友們知道選擇哪種壓力開關。
一、機械式壓力開關
機械式壓力開關為純機械形變導致微動開關動作，當壓力增加時，作用在不同的傳感壓力元器件（膜片、波紋管、活塞）產生形變，將向上移動，通過欄桿彈簧等機械結構，最終啟動最上端的微動開關，使電信號輸出。
二、智能壓力開關
智能壓力開關是用于測量各種氣體、液體的壓力，并將壓力信號轉換成標準信號來進行自動控制與安全保護的儀表。智能壓力開關的壓力傳感器采用了高精度半導體擴散硅敏感元件；采用4位LED實時數顯壓力，電路和結構采用了單片機技術、大規模集成電路以及新式的薄膜開關，因而具有電子顯示屏直觀，抗震動，響應快，穩定可靠，精度高的優勢。
三、隔爆型壓力開關
隔爆型壓力開關是應用在電力，化工，冶金，環保設備等爆炸區域以及強腐蝕性環境中，在原有壓力開關的基礎之上，通過堅固的密封殼體將容易爆炸的接線觸點密封起來，從而達到隔爆的效果。
