Abstract:
The inventive anemometer (1) is provided with: a thermocouple (5); a heater; an integrator circuit (11) for integrating a signal in response to the electromotive force from the thermocouple (5); an amplifier circuit (12) for amplifying the output from the integrator circuit (11); a comparator circuit (13) for outputting a reset signal for returning the integrator circuit (11) to a predetermined state when the output from the amplifier circuit (12) has exceeded an amplification output reference value; and a counter circuit (15) for measuring the wind speed on the basis of the intervals output by the reset signal. By virtue of this, an anemometer using a thermocouple can be provided at low cost.
