Yokogawa EJA110A Differential Pressure Transmitter

Specifications

1. 0.065 % High accuracy. 
2. Multi output for integration. 
3. Advanced Self diagnostics. 

      1.  Yokogawa EJA series uses a silicon resonant sensor technology.Monocrystalline silicon for the changes in pressure or temperature hysteresis does not exist.

     2. Single crystal silicon resonant sensor minimizes the effect of over voltage, temperature change, and static pressure and provides unmatched long-term stability.

      3. ASIC amplifier design to make diaphragm structure and flange miniaturization, reduces the number of parts, improve the reliability of the amplifier.

     4. The EJA series provides two modes of Fieldbus protocols as FUNDATION ™ fieldbus Low Voltage Mode and PROFIBUS PA devices, available to integrate Yokogawa and other suppliers to work together.

     5. The software side, the EJA series two AI function block calculates the differential pressure and static pressure in order to achieve a flexible instrument configuration.
