Wind Speed Sensor

Product introduction:

The wind speed sensor adopts the traditional three wind cups wind speed sensor structure, the wind cups choose carbon fiber material, high strength, good start; the signal processing unit embedded in the cups can output the corresponding wind speed signal according to the user's needs, can be widely used in meteorology, marine, environment, airports, ports, laboratories, industry and agriculture and transportation and other fields.

Wind speed sensor is used to measure wind speed equipment, compact and lightweight, easy to carry and assemble, three cup design concept can effectively obtain wind speed information, the shell is made of high-quality aluminum alloy profile or polycarbonate composite material, rain, corrosion resistance, anti-aging, is an easy to use, safe and reliable intelligent instrumentation.

What is the working principle of wind speed sensor

The sensing part is composed of three or four conical or hemispherical hollow cups. The hollow cup shell is fixed on a trigonal star-shaped bracket of 120° to each other or a cross-shaped bracket of 90° to each other, and the concave surface of the cup is arranged in one direction, while the whole cross-arm frame is fixed on a vertical rotation axis.

When the wind blows from the left, the wind cup 1 is parallel to the wind direction, and the pressure of the wind on the wind cup 1 is approximately zero in the direction of the most straight to the wind cup axis. Wind cup 2 and 3 with the wind direction into 60 degrees angle intersection, for the wind cup 2, its concave surface facing the wind, bear the largest wind pressure; wind cup 3 its convex surface facing the wind, the wind around the role of wind pressure than the wind cup 2 small, due to the wind cup 2 and wind cup 3 in the direction of the wind cup axis perpendicular to the pressure difference, and the wind cup began to rotate clockwise direction, the greater the wind speed, the greater the starting pressure difference, the greater the acceleration, the wind cup rotation The greater the wind speed, the greater the initial pressure difference, the greater the acceleration, the faster the wind cup turns.

After the wind cup starts to rotate, as cup 2 rotates in the direction of the wind, the pressure of the wind is relatively reduced, while cup 3 rotates at the same speed as the wind, the wind pressure is relatively increased, the wind pressure difference is decreasing, after a period of time (when the wind speed is constant), the partial pressure difference acting on the three wind cups is zero, the wind cup becomes uniform rotation. Thus, according to the speed of the wind cup (the number of revolutions per second) can determine the size of the wind speed.

The application of wind speed sensor is very wide, according to the actual needs of the site to choose a different signal output wind speed sensor. Wind speed sensor can be widely used in greenhouse, environmental protection, agriculture, ship, meteorology, breeding, wind mouth and other industries, and can be used in outdoor for a long time.
