Use Case: Pressure and temperature monitoring

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)
    • GW 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.
