The new ultrasonic wind speed and direction detector uses ultrasonic principles to detect horizontal wind speed and direction. The detector is completely made of corrosion-resistant materials and is anti-corrosion. The ultrasonic principle it adopts makes the measurement data more accurate and the initial measurement value lower. The use of ultrasonic waves to measure horizontal wind speed and direction solves the problem of traditional wind cup occlusion, thereby ensuring the accuracy of wind speed measurement in any direction, without dead corners and data incompleteness
Compared with traditional mechanical wind detectors, the threshold is lower , no moving parts, not easily damaged, easier to maintain
Has heating function, automatically starts heating at low temperatures, allowing wind measurement to be carried out in freezing weather and snowy days
Has multiple digital and analog output modes , and provide digital output interface. Its flexible design allows you to freely set data to be transmitted as required, and select the output unit and speed according to the provided software to ensure accuracy and reliability.
The measurement principle is based on the time of ultrasonic transmission between detector probes. The time it takes for ultrasonic waves to travel from one probe to another is related to the wind speed and ultrasonic path. The detector simultaneously measures the ultrasonic transmission time of the ultrasonic path in two directions on a probe. If the wind speed is zero, the transmission times for sending and returning are equal. The wind between the ultrasonic passages has a headwind propagation time that increases and a downwind propagation time that decreases. By measuring these two propagation times, the microcontrol unit calculates the wind speed between the passages. The measured wind speed is not affected by environmental factors such as altitude, temperature and humidity. It is a truly maintenance-free ultrasonic wind speed and direction detector.
