详细介绍

EJA210A/EJA220A法兰安装式差压变送器

EJA210A和EJA220A型高性能的法兰安装式差压变送器可用于测量结晶性或沉淀性液体的液位和密度。

产品信息

EJA210A和EJA220A型高性能的法兰安装式差压变送器可用于测量结晶性或沉淀性液体的液位和密度，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。
