Multi-Sensing

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.

    Ce transmetteur mesure avec précision la pression différentielle, la pression statique et la température du process ; il utilise ensuite ces valeurs dans un calculateur de débit embarqué hautes performances pour fournir un débit massique totalement compensé.

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.

Instrument configuration for measuring saturated steam

 

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.

Vue générale:

Yokogawa DPharp EJA/EJX Pressure transmitters do not need frequent re-zeroing due to superior long term stability, it contributes to reduce maintenance time.

Notes Applicatives
Vue générale:

La configuration du transmetteur de niveau peut prendre beaucoup de temps. Les calculs requis pour déterminer les valeurs de plage correctes pour les transmetteurs traditionnels peuvent devenir complexes en raison de la disposition physique d'une application.
