Dwyer ISDP系列 本安防爆型微差壓變送器

ISDP系列 本安防爆型微差壓變送器采用NEMA 4X的防護，輸出4-20mA信號，大屏的LCD顯示，可編程顯示差壓，流速或流量。可通過面板的按鍵來編程設置：安全級別，英制公制的工程單位，風速或風量，皮托管K系數，圓管，矩形管尺寸用于計算流量，等等。ISDP采用兩線制，10-35V電源，帶4針M-12連接頭。它的精度為0.5%， 量程范圍從0.25 - 100英寸水柱，還有正負雙向量程到10英寸水柱。這些使得ISDP變送器非常適用于危險場合來監測差壓或風速風量，防爆級別為Class I Div. I Groups A, B, C, D; Class II Div. I Groups E, F, G; Class III Div. I 。
