隔膜式壓力開(kāi)關(guān)(guān)
采用了隔膜設(shè)計(jì)壓力開(kāi)關(guān)(guān)是通過(guò)壓力通接連接處的導(dǎo)壓口作用于隔膜,使隔膜變形如果壓力大到壓力開(kāi)關(guān)(guān)的報(bào)警動(dòng)作點(diǎn)(diǎn)壓縮彈簧后就會(huì )帶動(dòng)接觸點(diǎn)(diǎn).通過(guò)接觸點(diǎn)(diǎn)的接通或打開(kāi)信號來(lái)監(jiān)控設(shè)備系統(tǒng)工作.
活塞式壓力開(kāi)關(guān)(guān)
內(nèi)置活塞與精密彈簧相連活塞的頂桿跟壓力通接連接處的導(dǎo)壓口相通,當(dāng)壓力變化時(shí)(shí)活塞的頂桿推動(dòng)彈簧伸縮量發(fā)(fā)生相應(yīng)變化,當(dāng)壓力達(dá)到設(shè)定值時(shí)(shí),會(huì )觸發(fā)(fā)預(yù)設(shè)得機(jī)械結(jié)構(gòu)并發(fā)(fā)出開(kāi)關(guān)(guān)信號。
?通用型,真空,差壓,特殊開(kāi)關(guān)(guān) ?現(xiàn)場(chǎng)調(diào)節(jié)或工廠(chǎng)設(shè)定 ?高耐壓 ?結(jié)實(shí)(shí)耐壓,性能可靠
