A multi-sensing transmitter is used to supply three different process readings to an external device. This could include a flow computer or RTU.
Yokogawa's Multivariable transmitter includes an option for RS485 Modbus communication to allow easy integration with other devices.
This transmitter precisely measures differential pressure, static pressure, and process temperature; then uses these values in a high-perfomance on-board flow computer to deliver fully compensated Mass Flow.
Designed specifically for high static pressure applications, this transmitter precisely measures differential pressure, static pressure, and process temperature; then uses these values in a high-perfomance on-board flow computer to deliver fully compensated Mass Flow.
Description of new features in HART7 communication (equipment revision 12 or later)
Saturated Steam Mode
Added the ability to calculate steam temperature from static pressure values using the steam table (international state formula IAPWS-IF97).
When saturated steam mode (ET Fixed =Saturated Steam) is set, steam temperature values can be calculated. In measurement function B (mass flow measurement), saturated steam flow rate can be measured without connecting an external thermometer.
Since operation under saturated steam is possible without using an external thermometer, engineering man-hours and procurement costs can be reduced.
Storage of User Flow Parameters
User Flow Parameters which is flow settings information input by FSA120 FlowNavigator R2.03 can be stored to the transmitter.
Reduces man-hours required for equipment setup and management, enabling rapid start-up of operation.
User Flow Parameters
- Primary Device and Pipe setup
- Fluid type setup
- Fluid operating range setup
- Fluid physical property setup
Display of Device history
Detailed equipment history information ,which are alarms and process data detected by the transmitter, could be displayed and output via the equipment DTM (FDT2.0) in the unlikely event of equipment failure.
This provides improved maintenance operations by reducing the troubleshooting time required in the event of equipment failure.
Yokogawa DPharp EJA/EJX Pressure transmitters do not need frequent re-zeroing due to superior long term stability, it contributes to reduce maintenance time.
