       smc壓力開關(guān)現(xiàn)貨大甩賣
日本SMC壓力開關(guān)是一種簡(jiǎn)單的壓力控制裝置，當(dāng)被測(cè)壓力達(dá)到額定值時(shí)，壓力開關(guān)可發(fā)出警報(bào)或控制信號(hào)。壓力開關(guān)的工作原理是：當(dāng)被測(cè)壓力超過額定值時(shí)，彈性元件的自由端產(chǎn)生位移，直接或經(jīng)過比較后推動(dòng)開關(guān)元件，改變開關(guān)元件的通斷狀態(tài)，達(dá)到控制被測(cè)壓力的目的。
      SMC壓力開關(guān)的工作原理：一般是使用“電接點(diǎn)壓力表"，這是一種普通的管彈簧壓力表，加上兩組電接點(diǎn)。
                                    
      可以接通相當(dāng)高低壓力的電接點(diǎn)，從而把壓力控制在上下限之間。這種電接點(diǎn)的容量小，只能開關(guān)接觸器的控制線圈，壓力表上的控制位置可以調(diào)節(jié)。
     
日本smc壓力開關(guān)主要采用壓力傳感器進(jìn)行壓力采樣，通過壓力傳感器直接將非電量—壓力轉(zhuǎn)換為可直接測(cè)量的電量—電壓或電流，再通過信號(hào)調(diào)理電路對(duì)傳感器信號(hào)進(jìn)行放大和歸整處理，zui后通過比較電路，使得該器件在所設(shè)定的壓力門限上，輸出電平是某一邏輯狀態(tài)，這個(gè)邏輯電平可輸入到微控制器，驅(qū)動(dòng)后部電路或控制電開關(guān)。
     
日本SMC是一家對(duì)差壓、壓力、溫度、液位和流量的測(cè)量,變送和控制等方面擁有眾多精密儀器儀表產(chǎn)品并且在價(jià)格上有強(qiáng)競(jìng)爭(zhēng)力的儀器儀表制造公司。產(chǎn)品主要包括差壓表,壓差計(jì),微差壓變送器,風(fēng)速計(jì)，風(fēng)量計(jì)，壓力變送器,壓力開關(guān),差壓開關(guān),壓力表、溫濕度傳感器、液位開關(guān),超聲波液位計(jì),液位變送器,流量開關(guān),流量計(jì),溫度開關(guān)及變送器、記錄器，閥門等等.
