Yokogawa EJX910A Multivariable pressure transmitter
The high performance EJX910A multivariable transmitter 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.
Additionally the HART protocol and FOUNDATION fieldbus protocol types are suitable to measure dynamically calculated and fully compensated mass flow for liquid, gas, or steam. 4 to 20 mA DC signal output is available in HART protocol type.
FDT/DTM* standard conforming software is available for transmitter configuration. FSA120 (FieldMateTM FlowNavigatorTM) is used for flow configuration of the HART protocol and FOUNDATION fieldbus protocol types.
Key features:
[HART protocol type]
• 1.0% mass flow rate accuracy over 1:10 flow range
• Advanced diagnostic function (option)
• 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]
• 1.0% mass flow rate accuracy over 1:10 flow range
• Advanced diagnostic function (option)
• 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)
