What is the wind speed sensor?

wind speed sensor is part of the tool used to measure wind speed. The scientific name of this tool is an anemometer, a device that usually includes both the wind direction and the wind speed sensor. The word "anemometer" comes from the Greek anemos for the wind. Anemometers are part of the standard device in the weather observation station and are used to measure wind speed at a specific height in the atmosphere. In addition, it is also possible to measure air current speed in the wind tunnel or for other applications involving gas flow speed and allows relative ventilation to estimate and allow a relative estimate of the fair and allows the relative estimate of the fair and allows relative estimate of the stainless estimation that relative estimation of attraction. Another common type of wind speed sensors is the Anemometer Cup, a rotary sensor with a cup that spins in the wind, controls the generator and the production of the electric output measured by the meter that was calibratedto the wind speed. The friction makes it difficult to calibrate the cup anemometer and affects the accuracy of the measurement. Cup anemometers are affordable and are the most commonly used wind speed sensors for a wide range of applications.

There are more sophisticated types of wind speed sensors that are useful for applications where accurate measurements are required. Thermoelectric wind speed sensors calculate the speed by measuring the speed at which the wind cools the heated conductor and is often used when the average speed is low. Pressure tubes are related to air pressure differences to wind speed and are used on aircraft and for other applications where air currents are stable and measured by average speeds are high. Ultrasonic and laser anemometers use the Doppler effect to estimate the wind Speed ​​by detecting the phase shift of sound or light reflected from the air molecules.

mechanical sensor speedWind losses, such as the Anemometer of the Cup, can be influenced by weather conditions, including low temperatures that could lead to the accumulation of ice. Hand anemometers are lightweight and portable, but tend to be less accurate and are usually used for firefighting or other situations, if portability is necessary, as well as for educational or recreational purposes. Calibrated wind speed sensors can be very expensive and can be delicate. These types of professional accurate sensors are essential for highly technical applications, such as estimating energy production in the design of wind turbine projects and storm predictions.
