Yokogawa EJA110A Differential Pressure Transmitter

Core Performance & Industrial Application

The Yokogawa EJA110A is a classic smart differential pressure transmitter of the EJA series, now discontinued.

It adopts single crystal silicon resonant sensor, converts differential pressure into standard 4-20mA signal with HART or BRAIN digital communication.

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

It features high accuracy of ±0.065% and excellent long-term stability, suitable for liquid, gas and steam media.

It is widely used for flow calculation, tank level measurement and filter differential pressure monitoring.

It can connect to Yokogawa DCS system, commonly used as spare replacement for old process plants.
