SMC 流量開關(guān)PF3W740-04-F-M長(zhǎng)期備貨
日本SMC流量開關(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)過電路轉(zhuǎn)換為對(duì)應(yīng)的接點(diǎn)信號(hào)或模擬量信號(hào)。
日本SMC流量開關(guān)重要技巧參數(shù)設(shè)定范疇:1~150cm/s(水),3~300cm/s(油),20~3m/s(空氣)信號(hào)輸出:PNP,NPN,繼電器,模仿量(4~20mA)供電:24V±20%DC接通電流:大400 mA(PNP或NPN型),大1A@24Vac/dc (繼電器型)空載電流:大80mA流量唆使:LED排 (6個(gè))設(shè)定方法:電位器設(shè)定耐壓范疇:100bar介質(zhì)溫度變更:≤4℃/s響應(yīng)時(shí)光:1~13s, 值2s初始化時(shí)光: 約8s電氣維護(hù):反相,短路,過載維護(hù)防護(hù)等級(jí):IP67介質(zhì)溫度:-20~80℃環(huán)境溫度:-20~80℃儲(chǔ)存溫度:-20~100℃材質(zhì):探頭:不銹鋼304(可選316L),外殼:不銹鋼304日本SMC流量開關(guān)重要利用:可對(duì)管道中的液體流動(dòng)情形舉行及時(shí)監(jiān)控,供給開關(guān)量輸出,并采取6個(gè)LED及時(shí)顯示流體流速狀況,實(shí)現(xiàn)下列監(jiān)控功效:介質(zhì)流動(dòng),下降/進(jìn)步流速; 介質(zhì)存在/不存在; 介質(zhì)流動(dòng)/靜止;可用于監(jiān)控管道內(nèi)流體流速巨細(xì)、斷流監(jiān)測(cè)或避免泵的空轉(zhuǎn)。
