1. Product
The high performance EJX930A multivariable transmitter features a single-crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam mass flow. The EJX930A outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure, static pressure, process temperature, or dynamically calculated and fully compensated mass flow.
FOUNDATION fieldbus protocol type is also available.
Key features:
• 1.0% mass flow rate accuracy over 1:10 flow range
• Advanced diagnostic function (option) [HART protocol type]
• Simultaneous dual output of 4 to 20mA and pulse signals.
• HART protocol revision selectable from 5 (HART 5) or 7 (HART 7)
• Long tag supporting up to 32 characters (HART 7)
• Enhanced burst mode and event notification(HART 7)
• SIL2 for safety requirement Note: HART 5 stands for HART protocol revision 5 HART 7 stands for HART protocol revision 7 [FOUNDATION Fieldbus protocol type]
• Various function blocks available; 5 AIs, AR, IT, SC, and IS as standard. PID as an optional feature.
• Cyclically displays up to 10 variables
• Software download function (option)
