DM-2000系列 帶數(shù)顯的微差壓變送器-德威爾Dwyer
DM-2000系列 帶數(shù)顯的微差壓變送器用于監(jiān)測(cè)空氣或其它兼容氣體的差壓,輸出標(biāo)準(zhǔn)的4-20mA。它和2000系列的Magnehelic微差壓表安裝開孔尺寸一樣,便于取代升級(jí)。有很多種量程供選擇,也可定制特殊量程。
采用玻璃鋼模壓的壓力接頭和外殼,安裝起來(lái)方便簡(jiǎn)單。數(shù)字按鍵校準(zhǔn)零點(diǎn)和量程。可選三位半LCD數(shù)顯來(lái)現(xiàn)場(chǎng)指示,根據(jù)不同的量程范圍,有4到6種工程單位供選擇。
