Yokogawa EJX430A-EAS4G-022DB Gauge Pressure Transmitter

Core Performance & Industrial Application

The Yokogawa EJX430A-EAS4G-022DB is a DPharp resonant sensor gauge pressure transmitter of EJX-A series.

It converts gauge pressure signal into standard 4-20mA analog signal with HART digital communication.

It supports remote configuration, zero trim and self-diagnosis via HART handheld communicator.

Multi-sensing technology can detect impulse line blockage and heat trace failure for advanced pipeline diagnosis.

It features excellent long-term stability and high accuracy, suitable for liquid, gas and steam media.

It can connect to Yokogawa DCS, widely used for pipeline pressure supervision and tank pressure monitoring.
