This measurement method includes wind cups, ultrasonic waves and laser Doppler anemometers.
1. Wind Cup Anemometer: Apply magnetic force to the axis of the wind cup to rotate it. As the wind cup rotates, the magnetic field lines also rotate. By measuring the rotational speed of magnetic field lines, wind speed can be calculated.
2. Ultrasonic Anemometer: Use the relationship between the speed of sound waves traveling through the air and the speed of the wind to measure wind speed. Wind speed can be calculated by emitting ultrasonic waves into the air and measuring the time it takes for the ultrasonic waves to travel through the air.
3. Laser Doppler Anemometer: Uses the Doppler effect to measure wind speed. When a laser beam passes through the air, particles in the air scatter the laser light and producea Doppler shift. By measuring the Doppler shift, wind speed can be calculated.
Sometimes we see many windmills on telephone poles or small balls rotating with the wind speed on the road. At that time we will be curious to know what these things are and what they do? In fact, these devices installed on telephone poles are wind speed sensors, which are mainly used in meteorology, laboratories and other testing equipment for scientific research to detect wind speed or weather monitoring. So we often see these wind speed sensors, what is their price and performance?

Wind speed and direction sensor DCF01A/DCF01C
DCF01A/ Wind speed DCF01C The wind direction sensor consists ofe of two parts: the DCF01A wind speed sensor and the DCF01C wind direction sensor. The wind speed sensor adopts the traditional three wind cup structure.The cup is made of carbon fiber, which has high strength and good start-up; the wind direction sensor uses a precision potentiometer, and a low-inertia light metal weather vane is used to respond to the wind direction and has good dynamic characteristics. The signal processing unit built into the cup body can output corresponding signals according to user needs.
This product has the advantages of wide measuring range, good linearity, strong lightning resistance, convenient observation, stability and reliability , etc. It can be widely used in meteorology, ocean, environment, airports, ports, laboratories. , industry, agriculture and transport andother areas.

The performance and function of wind speed sensors determine their unique role in scientific research. Today, with more and more tasks ofscientific research testing and laboratory scientific research, wind speed sensors are increasingly used, more and more manufacturers are producing them. wind speed sensors. In the competitive market environment, many manufacturers will produce wind speed sensors that are poor quality or do not meet scientific research standards. At present, we need to carefully analyze its performance and price. so don't be careless and buy a product that does not meet your requirements.
