  • Page 6: Wind Speed And Direction Sensor (Gmx200 And Gmx600)

    Wind Speed and Direction Sensor (GMX200 and GMX600) The MaxiMet uses the Gill WindSonic wind speed and direction sensor. The WindSonic measures the times taken for an ultrasonic pulse of sound to travel from the North (N) transducer to the South (S) transducer, and compares it with the time for a pulse to travel from S to N transducer.

  • Page 7: Radiation Shield (Gmx200 And Gmx600)

    Gill Instruments Ltd _____________________________________________________________________________________________________________ Radiation Shield (GMX200 and GMX600) A MetSpec Multi-Plate Radiation Shield is used. The special shield plate geometry, with its double louvre design, provides excellent response time performance of quick ambient temperature changes while still working effectively as a baffle to stop larger contaminants such as salt or dirt from reaching the temperature and humidity.
