Abstract

A three-dimensional anemometer containing thick film segmented thermistors for measuring wind speed using a heat loss method. Thick film segmented NTC thermistors are heated by their self-current under constant voltage supply. They have more segments connected in series to measure temperature in average; moreover they use internal electrodes to measure the temperature gradient and wind direction. The anemometer consists of 5 sensors: three measure wind speed on the x,y,z - axes, the fourth measures air temperature and the fifth measures humidity. The humidity sensor consists of two segmented thermistors put in Wheatstone bridge: the first is active -in contact with humidity and the second is isolated. The wind speed is obtained from calibration curves: thermistor current vs. wind speed, where temperature and humidity are parameters. The wind speed vector is obtained using projections on the axes. Then, modulo is calculated, and angles between speed vector and axes using modulo and projections on the axes. Data of 5 sensors are compared and applied using a PC for wind energy monitoring and remote control of windmill generators in real time.
