General Description

The MMW-005 uses a temperature sensitive element to measure wind direction and wind speed. The sensing element consists of a specially designed ceramic plate which incorporates an integrate circuit (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 assures a long lifespan with only a minimum of maintenance.
