采用微电子加工技术(MEMS)在一个单晶硅芯片表面的中心和边缘制作 两个形状、尺寸、材质*一致的H形状的谐振梁,谐振梁在自激振荡回路中作高频振荡。 单晶硅片的上下表面受到的压力不等时,将产生形变,导致中心谐振梁 因压缩力而频率减小,边缘谐振因受拉伸力而频率增加。 两频率之差信号直接送到CPU进行数据处理,然后 (1)经D/A转换成4-20mA输出信号,通讯时叠加Brain或Hart数字信号; (2)直接输出符合现场总线(Fieldbus Foundation TM)标准的数字信号。 2、 优异的性能 静压影响忽略不计 当加有静压(工作压力)时,两形状、尺寸、材质*一致的谐振梁形变相同, 故频率变化也一致,故偏差自动*(公式和图类似温度影响)。 单向过压特性优异 接液膜片与膜盒本体采用*创的波纹加工技术,使外部压力增大到某一数值时, 接液膜片能与本体*接触,硅油传递给传感器的压力不再随外力的增加而增 加,从而达到对传感器的保护作用。 横河EJA530系列压力变送器 EJA530A-DAS4N-09DE EJA530A-EAS4N-09DE EJA530A-DBS4N-09DE EJA530A-EBS4N-09DE EJA530A-DCS4N-09DE EJA530A-ECS4N-09DE EJA530A-DDS4N-09DE
