EJA310A Absolute Pressure Transmitter

YokogawaEJAThe 310A absolute pressure transmitter is used to measure the pressure of gases, liquids, and vapors, and then convert it into a 4-20mADC current signal output. The Yokogawa EJA310A pressure transmitter can also communicate with each other through the BRAN controller, CENTUM CS/μ XL, or Rosemount HART475 controller for setting and monitoring.
