ISDP系列 本安防爆型微差壓變送器-德威爾Dwyer
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(shè)置:安全級別,英制公制的工程單位,風(fēng)速或風(fēng)量,皮托管K系數(shù),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(fù)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(jiān)測差壓或風(fēng)速風(fēng)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 。
