Measurement Principle The Solid State Wind sensor uses a temperature
sensitive element to measure wind direction and
wind speed. The sensing element consists of a
specially designed ceramic plate which incorpo-
rates an IC. The IC temperature is maintained at
a constant value above ambient temperature.
Two pairs of thermocouples are mounted on the IC at right angles. If there is an airflow, the thermocouples measure the temperature difference over the IC surface. This is a measure
of the wind speed and direction.
Guide discs ensure that wind passes the sensor in
the right way. Mathematical processing by the
microprocessor and signal conditioner results in a
RS422 signal for wind speed and wind direction
according to the NMEA 0183 standard.
The wind sensor has no moving parts, which warranties a long lifespan with only a minimum of
maintenance. >
