美国DM-1000系列DWYER数显压差表
详细信息| 询价留言品牌:DWYER/德威尔 型号:DM-1000系列 加工定制:否 精度等级:1% 型号:DM-1000系列 加工定制:否
对DM-1000系列进行编程,仅仅需要通过菜单键进入4个醒目的子菜单,通过它们可以设定安全等级、选择工程单位、更改K系数(当使用不同的皮托管或流量传感器时)、设定圆形或方形管道尺寸(测量体积流量时)、更改过滤器设定点、查看*高/*低峰值数据、设定数字阻尼值用来平滑读数(用于读数波动较多的过程应用)、高级显示模式(用以节省电池),现场校准零点及量程。
DM-1000系列数字式差压表/风速表,具有1%FS的精度(量程大于2˝ W.C)及2%精度(量程0.25˝ W.C到1˝ W.C)。DM-1000具有多种供电方式,可以使用9-24VDC电源模块供电,也可以使用9V电池供电。而当使用电源模块供电且仪表具有9V电池时,电池将起到备份的作用,即当停电时9V电池将自动启动,使仪表继续正常运行。
