機(jī)械式風(fēng)速風(fēng)向傳感器是一種基于機(jī)械原理進(jìn)行風(fēng)速和風(fēng)向測量的設(shè)備。其風(fēng)速測量部分通常采用三杯或四杯旋轉(zhuǎn)式設(shè)計，當(dāng)風(fēng)吹動風(fēng)杯時，風(fēng)杯會隨風(fēng)速大小而旋轉(zhuǎn)，通過測量旋轉(zhuǎn)速度即可得知風(fēng)速。風(fēng)向測量部分則一般使用風(fēng)向標(biāo)，風(fēng)向標(biāo)的一端固定，另一端可隨風(fēng)向自由轉(zhuǎn)動，通過讀取風(fēng)向標(biāo)指示的方向即可得知風(fēng)向。機(jī)械式風(fēng)速風(fēng)向傳感器具有結(jié)構(gòu)簡單、運行穩(wěn)定、維護(hù)方便等優(yōu)點，廣泛應(yīng)用于氣象觀測、環(huán)境監(jiān)測、農(nóng)業(yè)氣象等領(lǐng)域，為相關(guān)領(lǐng)域的科研和生產(chǎn)提供了重要的數(shù)據(jù)支持。

A mechanical anemometer is a device that measures wind speed and direction based on mechanical principles. The wind speed measurement part usually adopts a threeup or four-cup rotary design. When the wind blows the cups, they rotate with the wind speed, and the wind speed can be known by measuring the rotation. The wind direction measurement part generally uses a wind vane. One end of the wind vane is fixed, and the other end can rotate freely with the wind. The wind direction can be known by reading the direction indicated by the wind vane. The anemometer has the advantages of simple structure, stable operation, and maintenance, and is widely used in meteorological observation, environmental monitoring, agricultural meteorology, and other fields, providing relevant
