Installation cost is reduced with a multi-variable transmitter. The EJX multi-variable transmitter combines three process variables in one transmitter. It removes the need to install a separate gauge pressure transmitter, temperature transmitter and flow computer. Dedicated software for configuring the flow calculation is available (FieldMate – Flow Navigator).
Customer Issues
- Installation cost of multiple field devices is high.
- Mass flow measurement is expensive.
Utilize EJX910A/930A + Flow Navigator
- From one multi-variable transmitter, you can measure differential pressure, static pressure, temperature and mass flow. The total cost is greatly reduced.
- Flow Navigator software provides a simple, user friendly method to configure the mass flow measurement.
Utilize FieldMate
- Flow Navigator has a step by step interface based on FDT/DTM technology. You can set the data by simply selecting the primary element, and inputting the flow rate information.
- You can copy the configuration of one transmitter to another transmitter to help with multiple configurations.
EJX Multi-Variable Transmitter Outputs
① In the case of HART digital / FOUNDATION Fieldbus /Modbus, these types of outputs can transmit multi process values at the same time.
② In the case of Analog signal (4-20mA), a multiplexer can be used to convert up to three values from HART signals into 4-20mA signals. The transmitter can transmit up to four values in conjunction with the original signal.
③ In the case of ISA100(wireless), the ISA 100 adaptor can transmit up to four values from the HART signal without reconstructing an existing line.

*1:In 4-20mA, output is one signal by one value。In HART, output is one signal by multiple value (up to four value).
*2:Number of output values is up to five.
*3:Flow, total flow, other temperature(flange)as output are not supported.
*4:Total flow is using HART or the pulse signal. 4-20mA signal is not supported. In FOUNDATION fieldbus, output is using IT function block.
