Working Principle of Wind Direction and Speed Sensor

The wind speed sensor is a conventional sensor that consistently gauges wind speed and air volume (air volume = wind speed x cross-sectional region). The wind speed sensor is generally characterized into a mechanical sort (principally a propeller type, a cup type) wind speed sensor, a hot air type wind speed sensor, a pitot tube wind speed sensor, and a ultrasonic wind speed sensor dependent on an acoustic rule.

We know that the fan drives the fan cutting edges to pivot by the engine, making a compel distinction between the sharp edges to push the wind current. The propeller anemometer work the other way. The cutting edge framework that lines up with the wind current is liable to wind pressure, which creates a certain torsional second to turn the edge framework. Typically the propeller-type speed sensor estimates the wind speed by pivoting a bunch of three-or four-bladed propellers around a level hub. The propeller is for the most part mounted on the facade of a weathervane so its plane of pivot is continually confronting the direction of the wind. Its speed relies upon the wind speed.

The wind speed and direction sensor is a typical wind speed sensor initially created by British Rubinson. The detecting segment comprises of three or four funnel shaped or hemispherical void cups. Empty cup shells are fixed on a trigeminal star section that is 120° separated or a 90° cross-molded section. The curved surfaces of the cups are characterized in one direction, and the whole cross arm outline is fixed on a vertical turning shaft.

At the point when the wind blows from the left, the wind cup 1 is corresponding to the wind direction, and the power of the wind against the cup 1 is around zero in the direction nearest to the hub of the cup. The wind cup 2 and 3 converge with the wind direction at a point of 60 degrees. the wind cup 2, the sunken surface faces the wind and the wind pressure is the best; the wind cup 3 has its raised surface confronting the wind, and the wind streams around it to make it subject to wind pressure. More modest than the wind cup 2, because of the pressing factor contrast between the cup 2 and the cup 3 in the direction opposite to the cup pivot, the cup begins to turn clockwise, and the wind speed is bigger, the underlying pressing factor distinction is bigger, bringing about The more noteworthy the speed increase, the quicker the cup turns.

After the wind cup begins to pivot, since the cup 2 turns in the direction of the wind, the pressing factor of the wind is moderately diminished, and the cup 3 pivots at a similar speed against the wind, the wind pressure is generally expanded, and the wind pressure contrast is persistently decreased. After a timeframe (when the wind speed is steady), when the halfway pressing factor contrast following up on the three wind cups is zero, the wind cup turns into a uniform pivot. Along these lines, the wind speed can be set up as indicated by the rotational speed of the cup (the quantity of turns each second).
