Title:
An anemoscope, a wind direction airflow meter, and the move direction measurement meter
Document Type and Number:
Japanese Patent JP6225940
Kind Code:
B2
Abstract:
A wind direction meter 1 has the following plurality of sensors 2 and a control unit 3. Each sensor 2 has a first surface 2a and has first and second interlayer connection members 21a, 21b made of different metals or semiconductors. Further, the wind direction meter includes a thermoelectric conversion element 21 which generates an electrical output when a temperature difference occurs between first ends 21aa, 21ba and second ends 21ab, 21bb of the respective first and second interlayer connection members 21a, 21b. The sensor 2 generates an electric output when the surrounding air, whose temperature has been changed by a heater 22, is moved by the wind to produce a temperature difference between the first ends 21aa, 21ba and the second ends 21ab, 21bb of the first and second interlayer connection members 21a, 21b. The control unit 3 calculates the direction of the wind on the basis of the difference in output. Thus, the wind direction of a weak wind can be detected with the wind direction meter 1.
