横河EJA430系列

文档简介横河EJA438W液位变送器一、zhuo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Zdi，从而提供无与伦比的长期稳定性。二、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。三、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PROFIBUSPA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总线通信能力.3051智能压力变送器3051C型差压、表压与压力变送器性能优异：精度0.075％量程比100：1差压量程从0-25Pa至13.8MPa表压量程从0-0.12KPa～13.8MPa绝压量程从0-2KPa至27.6MPa过程隔离膜片：不锈钢，哈氏合金C，蒙乃尔，钽（CD，CG）及镀金蒙乃尔设计小巧、坚固而质轻，易于安装。横河EJA30系列型号：EJA430A-DMS4A-97DAEJA430A-EMS4A-97DAEJA430A-EBS4A-97DAEJA430A-DMS4A-97NAEJA430A-EMS4A-97NAEJA430A-DAS4A-97NAEJA430A-EAS4A-97NAEJA430A-DBS4A-97NAEJA430A-EBS4A-97NAEJA430A-DMS-97DAEJA430A-EMS-97DAEJA430A-DAS-97DAEJA430A-EAS-97DAEJA430A-DBS-97DAEJA430A-EBS-97DAEJA430A-DMS-97NAEJA430A-EMS-97NAEJA430A-DAS-97NAEJA430A-EAS-97NAEJA430A-DBS-97NAEJA430A-EBS-97NAEJA430A-DMS4A-92DAEJA430A-EMS4A-92DAEJA430A-DAS4A-92DAEJA430A-EAS4A-92DAEJA430A-DBS4A-92DAEJA430A-EBS4A-92DAEJA430A-DMS4A-92NAEJA430A-EMS4A-92NAEJA430A-DAS4A-92NAEJA430A-EAS4A-92NAEJA430A-DBS4A-92NAEJA430A-EBS4A-92NAEJA430A-DMS-92DAEJA430A-EMS-92DAEJA430A-DAS-92DAEJA430A-EAS-92DAEJA430A-DBS-92DAEJA430A-EBS-92DAEJA430A-DMS-92NAEJA430A-EMS-92NAEJA430A-DAS-92NAEJA430A-EAS-92NAEJA430A-DBS-92NAEJA430A-EBS-92NAEJA430A-DMS4A-22DAEJA430A-EMS4A-22DAEJA430A-DAS4A-22DAEJA430A-EAS4A-22DAEJA430A-DBS4A-22DAEJA430A-EBS4A-22DAEJA430A-DMS4A-22NAEJA430A-EMS4A-22NAEJA430A-DAS4A-22NAEJA430A-EAS4A-22NAEJA430A-DBS4A-22NAEJA430A-EBS4A-22NAEJA430A-DMS-22DAEJA430A-EMS-22DAEJA430A-DAS-22DAEJA430A-EAS-22DAEJA430A-DBS-22DAEJA430A-EBS-22DAEJA430A-DMS-22NAEJA430A-EMS-22NAEJA430A-DAS-22NAEJA430A-EAS-22NAEJA430A-DBS-22NAEJA430A-EBS-22NAEJA430A-DMS4A-97DNEJA430A-EMS4A-97DNEJA430A-DAS4A-97DNEJA430A-EAS4A-97DNEJA430A-DBS4A-97DNEJA430A-EBS4A-97DAEJA430A-DMS4A-97NNEJA430A-EMS4A-97NNEJA430A-DAS4A-97NNEJA430A-EAS4A-97NNEJA430A-DBS4A-97NNEJA430A-EBS4A-97NNEJA430A-DMS-97DNEJA430A-EMS-97DNEJA430A-DAS-97DNEJA430A-EAS-97DNEJA430A-DBS-97DNEJA430A-EBS-97DNEJA430A-DMS-97NNEJA430A-EMS-97NNEJA430A-DAS-97NNEJA430A-EAS-97NNEJA430A-DBS-97NNEJA430A-EBS-97NNEJA430A-DMS4A-92DNEJA430A-EMS4A-92DNEJA430A-DAS4A-92DNEJA430A-EAS4A-92DNEJA430A-DBS4A-92DNEJA430A-EBS4A-92DNEJA430A-DMS4A-92NNEJA430A-EMS4A-92NNEJA430A-DAS4A-92NNEJA430A-EAS4A-92NNEJA430A-DBS4A-92NNEJA430A-EBS4A-92NN
