Description
| EJA440A型高性能的压力变送器可用于测量液体、气体或蒸汽的压力，然后将其转变成4～20mA DC的电流信号输出。 |
EJA系列支持BRAIN、HART和FOUNDATION™现场总线或PROFIBUS PA通信协议。 特性 - 卓越的性能和稳定性 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最低，从而提供无与伦比的长期稳定性。 - 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。 |
