1、EJA115型微小流量變送器是一款內(nèi)藏孔板的差壓變送器，特別適用于測(cè)量微小流量，然后將其轉(zhuǎn)變成4～20mADC的電流信號(hào)輸出。內(nèi)藏孔板有六種內(nèi)徑，范圍從0.508mm到6.350mm。孔徑的選擇結(jié)合差壓變送器的差壓測(cè)量量程，就可進(jìn)行大范圍的微小流量測(cè)量。EJA系列支持BRAIN、HART和FOUNDATION現(xiàn)場(chǎng)總線或PROFIBUSPA通信協(xié)議。115微小流量EJA變送器的規(guī)格EJA115微小流量變送器L膜盒M膜盒H膜盒水當(dāng)量0.016~7.2l/min0.022~23l/min0.07~33l/min空氣當(dāng)量0.4
