日本*SMC數(shù)字式流量開(kāi)關(guān)

流量開(kāi)關(guān)就是根據(jù)流量來(lái)指令系統(tǒng)的開(kāi)關(guān)的。

給流量開(kāi)關(guān)設(shè)定上限或者下限，當(dāng)流量達(dá)到此次限定值時(shí)，流量開(kāi)關(guān)發(fā)出信號(hào)或報(bào)警，系統(tǒng)將運(yùn)行或停止。一般要求流量的系統(tǒng)會(huì)采用流量開(kāi)關(guān)。

根據(jù)系統(tǒng)的不同，以及流量開(kāi)關(guān)型號(hào)等因素的不同，使用的地方也不同，要根據(jù)具體情況而定。

流量開(kāi)關(guān)工作原理

水流量開(kāi)關(guān)工作原理當(dāng)水流開(kāi)關(guān)內(nèi)有水流動(dòng)，水流量≥1.0L/min時(shí)，水流開(kāi)關(guān)內(nèi)的磁芯受水流推動(dòng)產(chǎn)生位移，磁芯位移帶動(dòng)磁源產(chǎn)生磁控作用使水流開(kāi)關(guān)輸出“通”信號(hào)。流量開(kāi)關(guān)快易優(yōu)自動(dòng)化選型有收錄，該信號(hào)輸入設(shè)備控制系統(tǒng)，經(jīng)控制系統(tǒng)實(shí)現(xiàn)控制作用，當(dāng)水流量小于啟動(dòng)流量時(shí)，水流開(kāi)關(guān)輸出“斷”的信號(hào)。控制系統(tǒng)產(chǎn)生與上述相反的控制作用。換句話說(shuō)就是：水流開(kāi)關(guān)當(dāng)管路中的水流量大于1L/min流量時(shí)，磁芯在水流作用下產(chǎn)生位移并帶動(dòng)磁源產(chǎn)生磁控作用使傳感器輸出"1"開(kāi)關(guān)信號(hào),該信號(hào)輸入到設(shè)備控制系統(tǒng)，經(jīng)功率擴(kuò)放大后實(shí)現(xiàn)以水流量控制的目的。當(dāng)管路中的水流量小于1L/min流量后，磁芯在復(fù)位彈簧推力作用下帶動(dòng)磁源回位，使傳感器輸出"0"開(kāi)關(guān)信號(hào),停止系統(tǒng)的工作。流量開(kāi)關(guān)具有靈敏度高、耐久性強(qiáng)等優(yōu)點(diǎn) 。
