Dwyer ISDP系列 本安防爆型微差压变送器
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 。
