SMC 流量開(kāi)關(guān)PF3W740-04-F-M長(zhǎng)期備貨
日本SMC流量開(kāi)關(guān)是利用探測(cè)頭溫度變化的原理設(shè)計(jì)。在探頭內(nèi)置發(fā)熱傳感器及感熱傳感器,并與介質(zhì)接觸。測(cè)量時(shí),發(fā)熱傳感器發(fā)出恒定的熱量,當(dāng)管道內(nèi)沒(méi)有介質(zhì)流動(dòng),感熱傳感器接收到的熱量是一個(gè)恒定值,當(dāng)有介質(zhì)流動(dòng)時(shí),感熱傳感器所接收到的熱量將隨介質(zhì)的流速變化而變化,感熱傳感器將這溫差信號(hào)轉(zhuǎn)化成電信號(hào),再經(jīng)過(guò)電路轉(zhuǎn)換為對(duì)應(yīng)的接點(diǎn)信號(hào)或模擬量信號(hào)。
