壓力控制器的壓力該如何控制
壓力開關采用高精度、高穩定性能的壓力傳感器和變送電路，實現對介質壓力信號的檢測、顯示、報警和控制信號輸出。壓力開關可以廣泛用于石油、化工、冶金、電力、供水等領域中對各種氣體、液體的表壓、絕壓的測量控制，是工業現場理想的智能化測控儀表。
其工作原理：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。
壓力開關外形比較精致小巧，安裝使用比較方便，可以同時控制系統內高壓端和低壓端的壓力。當系統內的壓力高于設備要求的安全壓力時，控制氣內的壓力感應器立即動作，使控制器內的微動開關斷開，此時設備停止工作，當系統內的壓力回到設備的安全壓力范圍時，控 制器內的壓力感應器立即復位，但由于控制器內的自鎖裝置已經工作的原因，微動開關不能接通，此時需要按壓力手動按鈕使微動開關接通，設備開始正常工作。
