Pressure and Temperature Monitoring at Refinery/Fertilizer Plants


Pressure and temperature monitoring at refinery/fertilizer plants

  • Replacement of the pressure and thermal gauges.
  • The gauge sensors in the existing system are off-line (no communication).


  • Daily manual reading of pressure and temperature gauges with report by phone.
  • The customer wants to change measurement from off-line to on-line.
  • Cabling for wired transmitters in huge plants (up to 300 meters long) is expensive.


  • Wireless pressure and temperature monitoring (Temporary installation for communication tests)
    • Gateway with 3 m extended antenna cable x1 on the roof of the control room
    • Transmitter (YTA and EJX) x 8
    • Repeater x2 on a tower which is about 40 m high. (One repeater covers 4 transmitters).
  • The maximum distance between the GW and transmitters is approximately 300 m.
  • Very high quality wireless communication via repeater was confirmed.


  • Eliminates wiring costs.
  • Eliminates manual gauge reading and maintenance costs.
  • Greater communication range than with Wireless HART.
  • Robust communication with lower packet error rates.

  • Chemical

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
