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 EJXMVTool™(FSA120), PC-based software that is exclusively designed for use with the EJX910A. EJXMVTool™ 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

[HART protocol type]

•

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

[FOUNDATION™ fieldbus protocol type]

•

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

•

Cyclically displays up to 10 variables

•

Software download function(option)

•

Advanced diagnostic function (option)
