Yokogawa EJX110A Differential Pressure Transmitter

Core Performance & Industrial Application

The Yokogawa EJX110A belongs to EJX-A OpreX series traditional mount differential pressure transmitter.

It adopts DPharp single crystal silicon resonant sensing technology, can measure differential pressure and static pressure simultaneously.

It outputs 4-20mA analog signal plus digital communication, supports HART, BRAIN, FF and PROFIBUS PA optional.

It features excellent long-term stability of ±0.1% per 15 years, fast response and built-in advanced impulse line blockage diagnosis.

It supports local LCD indicator, on-site parameter setting, explosion-proof and SIL2/3 safety certification for hazardous areas.

It is widely used for flow, liquid level, density and differential pressure monitoring in petrochemical, oil & gas and power plants.
