YOKOGAWA EJX930A Multivariable Transmitter

Introducing the Yokogawa EJX930A multivariable transmitter, a remarkable innovation in multi-sensing technology that makes optimal use of the powerful characteristics of the single-crystal silicon resonant sensor. Experience FlowNavigator (FSA120), PC-based software that is exclusively designed for use with the EJX930A. FlowNavigator enables users to configure mass flow and achieve accurate measurements with real-time full density compensation. Key features include:

l 1.0% mass flow rate accuracy

l Fully compensated mass flow: all flow factors can be automatically and dynamically calculated to an optimal value

l Advanced diagnostic function (option) [HART protocol type]

l Simultaneous dual output of 4 to 20 mA and pulse signals for total flow, flow rate, or alarm status

l HART protocol revision selectable from HART 5 or HART 7

l Long tag supporting up to 32 characters (HART 7)

l Enhanced burst mode and event notification (HART 7)

l SIL2 for safety requirement [FOUNDATION fieldbus protocol type]

l Various function blocks available; 5 Als, AR, IT, SC, and IS as standard PID as an optional feature

l Cyclically displays up to 10 variables

l Software download function(option)

In case ordering HART communication, it is recommended to specify output signal code -J (HART 5/HART 7 selectable) than -E (HART 5 only). EJX-A Series except multivariable transmitters (EJX910A/EJX930A) already released "Output signal code -J" for HART 7 only. In this case HART protocol revision cannot be selected from HART 5 or HART 7. Protocol revision supported by HART configuration tool must be the same or higher than that of the EJX multivariable transmitter.
