空調(diào)過濾網(wǎng)DWYER差壓表2000系列被廣泛應(yīng)用于監(jiān)測(cè)風(fēng)機(jī)出口靜壓，過濾器阻力，測(cè)量風(fēng)速，通風(fēng)狀態(tài)，測(cè)量孔板兩邊的差壓，還用于吹泡液位測(cè)量系統(tǒng)監(jiān)測(cè)液位，監(jiān)測(cè)氣體，空氣的混合控制比例，在醫(yī)療設(shè)備和裝置中監(jiān)測(cè)血壓，和呼吸壓力等。
空調(diào)過濾網(wǎng)DWYER差壓表2000系列利用簡(jiǎn)潔、無摩擦的磁性移動(dòng)部件，可以迅速測(cè)量出空氣等非腐蝕性氣體的正壓、負(fù)壓或差壓
空調(diào)過濾網(wǎng)DWYER差壓表2000系列設(shè)計(jì)抗沖擊、防震并且有過載保護(hù)
空調(diào)過濾網(wǎng)DWYER差壓表2000系列有81種量程范圍可供選擇，精度為2%。采用了無磨損的機(jī)芯，結(jié)構(gòu)簡(jiǎn)單可靠，可快速靈敏地指示氣體的微小正壓，負(fù)壓或差壓，它還具備防震和過壓保護(hù)的功能。Magnehelic®微差壓表的價(jià)格經(jīng)濟(jì)合理，使用方便，避免了測(cè)量中的液體差壓計(jì)的液體蒸發(fā)，結(jié)凍和必須水平矯正等問題。
