ULTIMATE TECHNOLOGY WITH A LIMITED INVESTMENT Pillard Windcross™ propose Ultrasonic technology to measure wind velocity and direction. The Ultrasonic technology is based on sound propagation through the air; two transducers are alternately transmitters and receivers. The outward and return transit times induced by the air flow are measured. Using the time difference, the internal calculator measures the wind speed and direction compared to its reference axis. The measured value allows automatic activation of ventilation when required. Power supply Power consumption Operating temperature Analog...
