YOKOGAWA EJX930A High-performance Multivariable Transmitter Pressure Transmitter

The EJX930A high-performance multivariable transmitter adopts a single crystal silicon resonant sensor, which can output and measure differential pressure, static pressure, process temperature, and calculate mass flow rate, suitable for high static pressure applications. Supports multiple protocols such as HART, FOUNDATION fieldbus, and RS485 Modbus.

Core functions

1. Multivariate measurement:

Differential pressure accuracy ± 0.04%, static pressure accuracy ± 0.1%, external temperature measurement range -200~800 ℃ (accuracy ± 0.5 ℃)；

Support mass flow calculation with an accuracy of ± 1.0%, suitable for flow measurement of gases, liquids, and vapors；

2. Communication protocol compatibility:
