Product Details
EJA430A pressure transmitterUsed to measure the pressure of gases, liquids, and vapors, and then convert it into a 4-20mADC current signal output. The Yokogawa EJA430A pressure transmitter can also communicate with each other through the BRAN controller, CENTUM CS/μ XL, or Rosemount HART 475 controller for setting and monitoring.
