描述
PGS11 switchGAUGE型压力表结合了波登管压力表和压力开关。该型号压力表具备模拟显示功能,无论是否存在电源,操作人员都可以现场读取测量值。此外,该压力表还可以在无电势的情况下转换电信号。西安奥信自动化仪表公司 专业代理 029-86691808 86691828.预设切换值由表盘上有红色标记的指针指示,并且用户可根据需要随时将切换值设置为量程的10%至90%。然后,压力表就可以根据指针的位置,接通或断开电路。因此,switchGAUGE系列压力表可用于过程监测,如控制气瓶或液压回路中的液位。 西安奥信自动化仪表公司 专业代理 029-86691808 86691828switchGAUGE系列标准型压力表的量程为0 ... 0.25至0 ... 40 MPa,精度等级为2.5,电气连接件为1m长的圆形电缆。
该型号压力表具备各种选件(如更高的精度等级、不同的电缆长度、在仪表外围8点钟方向的电缆出口),可以完全满足用户的所有应用要求。
该型号压力表根据EN837-1标准而设计,完全符合相关要求。
