膜片式壓力開關的簡單介紹
壓力開關根據傳感器元件劃分時有圈彈簧管壓力開關、膜片壓力開關、膜盒壓力開關及波紋管壓力開關等等，今天小編主要為大家介紹膜片式壓力開關。
一、膜片式壓力開關的工作原理
當系統內壓力高于或低于額定的安全壓力時，感應器內碟片瞬時發生移動，通過連接導桿推動開關接頭接通或斷開，當壓力降至或升額定的恢復值時，碟片瞬復位，開關自動復位，從而達到壓力控制的目的。
二、膜片式壓力開關的特點
膜片式壓力開關采用了不銹鋼的材質，滿量程可調，可以實現上限值與下限值的調節，性能穩定可靠，動作點靈活。
三、膜片式壓力開關的應用
由于膜片式壓力開關采用了不銹鋼的材質，所以可以測量腐蝕性介質，在濕度較高的場合使用。
