Features of ultrasonic wind speed sensor_application of ultrasonic wind speed sensor in production and life
The flow of air forms the wind. The wind in life can be divided into many types according to different wind speeds. Winds over 8 levels are usually more dangerous. Therefore, people have always paid more attention to the measurement of wind speed. With sensors With the continuous development and improvement of technology, wireless communication technology, and computing technology, various sensor networks will spread all over our living environment, so as to truly realize 'ubiquitous computing'. Let's take a look at the relevant knowledge of the wind speed sensor. The wind speed sensor is an intelligent instrument with convenient use, good performance and high reliability. It can be widely used to measure wind speed in greenhouses, environmental protection, weather stations and breeding places. There are many types of wind speed sensors, which can be divided into Pitot tube wind speed sensors, propeller wind speed sensors, Hall effect electromagnetic wind speed sensors, hot wire wind speed sensors, and ultrasonic wind speed sensors. Compared with the traditional wind speed sensor, the ultrasonic wind speed sensor has the advantages of good measurement accuracy and multiple functions, and the structure of its probe is relatively simple. It replaces the traditional wind speed and direction sensor in many application fields. People will choose ultrasonic wind speed sensors in some field accurate measurement work, such as: urban environmental monitoring, wind power generation, weather monitoring, bridges and tunnels, marine ships, aviation airports, various fan manufacturing industries, industries that require exhaust ventilation systems, etc. In the actual application process, the measurement of wind speed and wind direction generally exist at the same time. Below we mainly introduce the advantages and characteristics of the ultrasonic wind speed and direction sensor and some applications. Take the ultrasonic wind speed and direction sensor RS-CFSFX-NO1-2 as an example: The ultrasonic wind speed and direction sensor mainly uses the ultrasonic time difference method to measure wind speed and direction. The air velocity in the breeze direction is superimposed. If the propagation direction of the ultrasonic wave is the same as the wind direction, its speed will increase; otherwise, its speed will slow down. Therefore, under fixed detection conditions, the speed of ultrasonic propagation in the air can correspond to the wind speed function, and accurate wind speed and wind direction can be obtained by calculation. 1. Product features:1. The ultrasonic wind speed and direction sensor adopts an upside-down design, which can avoid rain and snow interference, and is not afraid of blockage by wind and sand. Compared with products without upside-down design on the market, the measurement is more accurate. Longer life. This technology has applied for a national patent. 2. The ultrasonic wind speed and direction sensor is equipped with a built-in electronic compass selection device. There is no longer an orientation requirement during installation, and it only needs to be installed horizontally. There is no need to ensure that the N on the shell must point to the north during installation. 3. The ultrasonic wind speed and direction sensor has no start-up wind speed limit, zero wind speed work, no angle limit, 360° omni-directional measurement, breakthrough angle troubles, wind speed and wind direction data can be obtained at the same time. 4. The ultrasonic wind speed and direction sensor adopts random error identification technology, which can ensure low dispersion error of measurement under strong wind and ensure stable output data. 5. The housing of the ultrasonic wind speed and direction sensor is made of high-quality ABS material, which is light in weight, easy to carry, and easy to disassemble. 6. The ultrasonic wind speed and direction sensor adopts an integrated design, IP66 high protection level, no moving parts, low wear, and a longer service life. It can easily deal with various harsh environments and ensure stable data output Precise. Second, the scope of application: Ultrasonic wind speed and direction sensors have a wide range of applications. In addition to wind power generation and weather monitoring as everyone knows, they can also be used in navigation ships, mining, airports, ports, and experiments. Various fields such as laboratories, industry, agriculture and transportation. Ultrasonic wind speed and direction sensors in many places bring people not only data, but also a guarantee of safety. For example, in mines, mine accidents caused by insufficient ventilation often occur. Therefore, we need to know in real time More accurate data underground to avoid unsafe factors in time. Traditional methods have the problems of low accuracy and poor stability in the measurement of wind speed and direction. However, the emergence of ultrasonic wind speed and direction sensors not only facilitates us to accurately collect data, but also guarantees the safety of personnel and property.
Currently there is a global trend growing. People are more conscious about OEM sensor and are seeking alternatives to traditional solutions.
