Multi-sensing, an Evolution in the Silicon Resonant Sensor

EJX910A Multivariable Transmitter

Product Information

Introducing the Yokogawa EJX910A 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 EJX910A. FlowNavigator enables users to configure mass flow and achieve accurate measurements with real-time full density compensation. Key features include:

•

1.0% mass flow rate accuracy

•

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

•

Advanced diagnostic function (option)

[HART protocol type]

•

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

•

HART protocol revision selectable from HART 5 or HART 7

•

Long tag supporting up to 32 characters (HART 7)

•

Enhanced burst mode and event notification (HART 7)

•

SIL2 for safety requirement

Flow Configuration Software (FSA120)

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.

		Protocol revision supported by HART configuration tool
		HART 5	HART 7
Protocol revision of EJX multivariable transmitter	HART 5	○	○
Protocol revision of EJX multivariable transmitter	HART 7	-	○

○	: Communication OK
-	: Communication NG

HART 7 communication is supported by FieldMate R2.02 or later.
