The EJX910A multivariable pressure transmitter is part of Yokogawa's DPharp transmitter series. It features multi-sensing technology with a single-crystal silicon resonant sensor that outputs the measured differential pressure, static pressure and process temperature, which covers multiple protocols: HART, FOUNDATION fieldbus and RS485 Modbus.

FieldMate FlowNavigator™ is a PC-based software that is exclusively designed for use with the EJX910A / EJA930A. It uses FDT/DTM standards to enable users to configure mass flow and achieve accurate measurements with real-time full density compensation.
For Differential pressure transmitters, Yokogawa offers a complete line of IEC 61518 compliant 3-Valve and 5-Valve manifolds. Available in T-Style, H-Style, Wafer-Style, and Bottom Process Connection Style and can be ASME B31.1 (Power) Compliant, ISO 15848 Compliant, or TA-Luft Compliant.
Direct-immersion RTD sensor (Thermowells Available)
Join Applications Engineer Michael Keller as he guides you through the steps for connecting the EJX910 Modbus with the USB Modbus converter.
Yokogawa presents a brief tutorial on configuring Stardom RTU to communicate with EJX Multivariable Pressure and Temperature transmitter via Modbus RTU over RS485. Appropriate function blocks and settings within Logic Designer are covered in order to read in the primary three variables DP, SP, and Temperature. Also a quick review of FieldMate and Kepware OPC Server are shown as examples of ways to review and change the settings of the EJX 910 Modbus MV transmitter.
