1. Overview

The Yokogawa EJX110A (also referenced as Yokogawa EJX110A differential pressure transmitter) is a high-performance differential pressure transmitter featuring an advanced single-crystal silicon resonant sensor. It is engineered for precise measurement of liquid, gas, and steam pressure.

For a complete technical breakdown, you can reference the official Yokogawa EJX110A datasheet or ejx110a datasheet for deep parameter configurations. The transmitter outputs a standard 4 to 20 mA DC signal corresponding to the measured differential pressure. Additionally, its multi-sensing technology can measure static pressure, which can be viewed directly on an integral indicator or monitored remotely via BRAIN or HART communications.
