/*本風(fēng)速傳感器采用小型直流有刷電機(jī)與三杯式旋轉(zhuǎn)風(fēng)杯組裝
而成，其工作原理為，當(dāng)環(huán)境有水平流動(dòng)風(fēng)時(shí)，旋轉(zhuǎn)風(fēng)杯能夠產(chǎn)生旋轉(zhuǎn)，并帶動(dòng)小型電機(jī)產(chǎn)生電壓，其電壓與旋轉(zhuǎn)速度基本成正比。利用此信號(hào)電壓，可以對(duì)環(huán)境風(fēng)速進(jìn)行測(cè)量。這款風(fēng)速傳感器采用海洋軍用的高精度測(cè)量風(fēng)速傳感器，與傳統(tǒng)產(chǎn)品先別，具有更高精度;是建筑機(jī)械(起重機(jī)、履帶吊、門吊、塔吊)、鐵路、港口、碼頭、風(fēng)力發(fā)電、光伏發(fā)電、電廠、氣象、索道、環(huán)境、溫室、養(yǎng)殖等領(lǐng)域不可缺少的風(fēng)速檢測(cè)裝置。用它可以實(shí)現(xiàn)設(shè)備風(fēng)速指示數(shù)字化及自動(dòng)化，是相關(guān)設(shè)備不可缺少的風(fēng)速檢測(cè)設(shè)備。*/
