HYDAC電子壓力開關(guān)詳細(xì)參數(shù)適合多種行業(yè)

Electronic pressure switches offer a multitude of advantages in comparison with mechanical pressure switches and contact manometers. They convince though greater accuracy, freedom from wear, long-term stability, simpler operation and the high number of switching cycles, among other things.

主要特點(diǎn)
HYDAC電子壓力開關(guān)主要類別包括常開式和常閉式。主要特點(diǎn)是：
1,、采用英制管螺紋快速接頭或銅管焊接式安裝結(jié)構(gòu)，安裝靈活,，使用方便，無需特殊的安裝固定,。
2、插片式導(dǎo)線式連接方可供用戶任意選定,。
3、密封式不銹鋼感應(yīng)器安全可靠,。
4、壓力范圍內(nèi)可根據(jù)用戶任意選定的壓力值進(jìn)行制造,。
壓力開關(guān)是與電器開關(guān)相結(jié)合的裝置，當(dāng)?shù)竭_(dá)預(yù)先設(shè)定的流體壓力時(shí),，開關(guān)接點(diǎn)動(dòng)作,。主要應(yīng)用于電廠、石化,、冶金行業(yè)等工業(yè)設(shè)備上輸出報(bào)警或控制信號(hào),，在工業(yè)領(lǐng)域中有著重要的用途，能預(yù)防生產(chǎn)工程中重要裝置的損壞,，避免了重大生產(chǎn)事故地發(fā)生。 

工作原理
HYDAC電子壓力開關(guān)的工作原理：是當(dāng)系統(tǒng)內(nèi)壓力高于或低于額定的安全壓力時(shí),，感應(yīng)器內(nèi)碟片瞬時(shí)發(fā)生移動(dòng),，通過連接導(dǎo)桿推動(dòng)開關(guān)接頭接通或斷開,，當(dāng)壓力降至或升額定的恢復(fù)值時(shí)，碟片瞬時(shí)復(fù)位,，開關(guān)自動(dòng)復(fù)位,，或者簡單的說是當(dāng)被測壓力超過額定值時(shí),，彈性元件的自由端產(chǎn)生位移,，直接或經(jīng)過比較后推動(dòng)開關(guān)元件，改變開關(guān)元件的通斷狀態(tài),，達(dá)到控制被測壓力的目的,。HYDAC電子壓力開關(guān)采用的彈性元件有單圈彈簧管、膜片,、膜盒及波紋管等,。
