Pressure and Temperature Monitoring at Refinery/Fertilizer Plants

Application

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).

Challenges

  • 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.

Solutions

  • 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.

Benefits

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