ISDP系列 本安防爆型微差压变送器 采用NEMA 4X的防护,输出4-20mA信号,大屏的LCD显示,可编程显示差压,流速或流量。可通过面板的按键来编程设置:安全级别,英制公制的工程单位,风速或风量,皮托管K系数,圆管,矩形管尺寸用于计算流量,等等。ISDP采用两线制,10-35V电源,带4针M-12连接头。它的精度为0.5%, 量程范围从0.25 - 100英寸水柱,还有正负双向量程到10英寸水柱。这些使得ISDP变送器非常适用于危险场合来监测差压或风速风量,防爆级别为Class I Div. I Groups A, B, C, D; Class II Div. I Groups E, F, G; Class III Div. I 。
