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.
