• Model EJX910A Multivariable 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 (FieldMate™ FlowNavigator™) is used for flow configuration of the HART protocol and FOUNDATION fieldbus protocol types.
    *: FDT (Field Device Tool): Defines the system environment in which the DTM runs. DTM (Device Type Manager): The application which defines the graphical user interface (GUI) specific to the device.
