The Wind Speed Transmitter works by sensing airflow velocity using either an ultrasonic sensor or a cup/vane anemometer mechanism. As wind passes through, the sensor measures the speed based on time-of-flight (ultrasonic) or rotational speed (mechanical). The signal is then converted into an electrical output, processed by the transmitter, and sent as analog or digital data. This enables real-time monitoring of wind conditions for HVAC systems, weather stations, and safety controls, ensuring accurate and reliable performance in various environments.
