日本*SMC數(shù)字式流量開關(guān)

流量開關(guān)就是根據(jù)流量來指令系統(tǒng)的開關(guān)的,。

給流量開關(guān)設(shè)定上限或者下限，當(dāng)流量達到此次限定值時,，流量開關(guān)發(fā)出信號或報警,，系統(tǒng)將運行或停止。一般要求流量的系統(tǒng)會采用流量開關(guān),。

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

流量開關(guān)工作原理

水流量開關(guān)工作原理當(dāng)水流開關(guān)內(nèi)有水流動，水流量≥1.0L/min時,，水流開關(guān)內(nèi)的磁芯受水流推動產(chǎn)生位移,，磁芯位移帶動磁源產(chǎn)生磁控作用使水流開關(guān)輸出“通”信號。流量開關(guān)快易優(yōu)自動化選型有收錄,，該信號輸入設(shè)備控制系統(tǒng),，經(jīng)控制系統(tǒng)實現(xiàn)控制作用，當(dāng)水流量小于啟動流量時,，水流開關(guān)輸出“斷”的信號,。控制系統(tǒng)產(chǎn)生與上述相反的控制作用,。換句話說就是：水流開關(guān)當(dāng)管路中的水流量大于1L/min流量時,，磁芯在水流作用下產(chǎn)生位移并帶動磁源產(chǎn)生磁控作用使傳感器輸出"1"開關(guān)信號,該信號輸入到設(shè)備控制系統(tǒng)，經(jīng)功率擴放大后實現(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磁源回位，使傳感器輸出"0"開關(guān)信號,停止系統(tǒng)的工作,。流量開關(guān)具有靈敏度高,、耐久性強等優(yōu)點 ,。
