特性
- 的性能和稳定性
EJA系列采用单晶硅谐振式传感器技术。单晶硅对于压力或温度的变化不存在滞后现象,是非常理想的材料。单晶硅谐振式传感器将过压、温度变化和静压影响降为zui低,从而提供的长期稳定性。
- 小型轻量设计
由于采用ASIC放大器设计使包装变小,以及膜盒构造和法兰的小型化,这款机型的重量降到了原有机型的一半。ASIC设计不仅减少了零件数量,而且提高了放大器的可靠性。
- 现场总线通信能力
现场总线是双向数字通信系统,是配置仪表控制系统的革新技术,同时也是前景很好的更新换代产品,用于替换现在现场仪表中广泛使用的标准4~20mA模拟通信。
EJA系列提供两种现场总线模式,FOUNDATION™现场总线低压模式和PROFIBUS PA设备,以实现横河电机和其他供应商的协同工作。软件方面,EJA系列采用两个AI功能块计算差压和静压,从而实现灵活的仪表配置。
