SMC數(shù)字式流量開(kāi)關(guān)#smc廣州一級(jí)現(xiàn)貨
SMC流量開(kāi)關(guān)的熱導(dǎo)示流器是基于熱交換原理設(shè)計(jì)，探頭內(nèi)置發(fā)熱模塊以及感熱模塊,，示流器的熱量傳導(dǎo)與被測(cè)流體流速密切相關(guān),，如果管道內(nèi)沒(méi)有介質(zhì)流動(dòng),，感熱模塊接收到的熱量是一個(gè)固定值，而當(dāng)流體介質(zhì)流過(guò)示流器探頭時(shí),，感熱模塊所接收到的熱量隨介質(zhì)的流速變化而變化,，感熱模塊再將這溫差信號(hào)轉(zhuǎn)化成電信號(hào)，處理器再將其轉(zhuǎn)換成4～20mA電信號(hào)或與設(shè)定流量對(duì)應(yīng)的接點(diǎn)信號(hào)輸出,。熱導(dǎo)示流器將流量探頭和信號(hào)處理器一體化集成,，六個(gè)LED指示燈提供了流動(dòng)狀態(tài)的趨勢(shì)顯示，開(kāi)關(guān)動(dòng)作值可以簡(jiǎn)單的通過(guò)前面板上保護(hù)螺釘下的電位器進(jìn)行調(diào)節(jié),，LJ1-1-Y05
