Yokogawa EJX910A Multivariable Pressure Transmitter

Yokogawa EJX910A Multivariable Pressure Transmitter

Product Introduction

The Yokogawa EJX910A is a high-performance multivariable transmitter designed for precise measurement of differential pressure, static pressure, and process temperature in industrial applications. Leveraging single-crystal silicon resonant sensor technology, it offers exceptional accuracy (±0.04% for differential pressure) and supports multiple protocols (HART, FOUNDATION Fieldbus, Modbus). Ideal for mass flow measurement in liquid, gas, or steam systems, the EJX910A provides fully compensated readings and integrates with FDT/DTM software for seamless configuration. Part of Yokogawa’s OpreX Field Instruments family, it meets SIL 2/3 safety standards and delivers reliability in demanding processes.
