風途科技品牌超聲波風速風向傳感器（型號：FT-WQX2）利用超聲波在空氣中的傳播時間差來測量風速及風向，結構堅固，儀器抗腐蝕性強，在安裝和使用時無需擔心損壞，設計靈活，輕巧，攜帶輕便，安裝、拆卸容易；信號接入方便,目前設計有數字量RS485通訊和模擬量4-20mA兩種信號輸出類型，文末有技術指標。

　　在地(di)(di)(di)(di)(di)球(qiu)的(de)(de)(de)外表面(mian)包圍著(zhu)一(yi)層空(kong)(kong)氣，由(you)于(yu)地(di)(di)(di)(di)(di)球(qiu)引力的(de)(de)(de)作用靠地(di)(di)(di)(di)(di)面(mian)的(de)(de)(de)空(kong)(kong)氣密度(du)(du)大壓力大、離地(di)(di)(di)(di)(di)面(mian)遠(yuan)些的(de)(de)(de)空(kong)(kong)氣密度(du)(du)小(xiao)壓力小(xiao)。太陽(yang)照(zhao)熱(re)地(di)(di)(di)(di)(di)面(mian)使地(di)(di)(di)(di)(di)面(mian)的(de)(de)(de)空(kong)(kong)氣密度(du)(du)減(jian)小(xiao)上升、又(you)由(you)于(yu)各(ge)地(di)(di)(di)(di)(di)表面(mian)對太陽(yang)的(de)(de)(de)吸收(shou)與反(fan)射不(bu)同(tong)(tong)(tong)、地(di)(di)(di)(di)(di)球(qiu)不(bu)同(tong)(tong)(tong)緯度(du)(du)的(de)(de)(de)溫(wen)度(du)(du)不(bu)同(tong)(tong)(tong)造成各(ge)地(di)(di)(di)(di)(di)空(kong)(kong)氣密度(du)(du)不(bu)同(tong)(tong)(tong)、地(di)(di)(di)(di)(di)球(qiu)自轉使地(di)(di)(di)(di)(di)面(mian)溫(wen)度(du)(du)晝夜(ye)交替(ti)變化等(deng)等(deng)都促成空(kong)(kong)氣的(de)(de)(de)不(bu)停流(liu)動(dong)，同(tong)(tong)(tong)時由(you)于(yu)地(di)(di)(di)(di)(di)球(qiu)的(de)(de)(de)自轉也造成空(kong)(kong)氣的(de)(de)(de)流(liu)動(dong)，這就是(shi)風的(de)(de)(de)形成原因。流(liu)動(dong)的(de)(de)(de)空(kong)(kong)氣具有(you)的(de)(de)(de)能量就是(shi)風能。

　　風(feng)力(li)不僅(jin)有大小還有方向(xiang)(xiang)，可通過儀(yi)器來(lai)測量(liang)風(feng)力(li)的大小與方向(xiang)(xiang)。根據測量(liang)原(yuan)理主要有以下幾類：機械式、超聲波式、聲振蕩、壓力(li)式與熱線(xian)式等，在一般場合用得較多的是機械式與超聲波式。

　　與傳統(tong)機械式(shi)風(feng)(feng)速(su)風(feng)(feng)向傳感(gan)器(qi)相比，超(chao)聲波風(feng)(feng)速(su)風(feng)(feng)向傳感(gan)器(qi)具(ju)有明顯的優點：不(bu)存在轉(zhuan)動(dong)部件，不(bu)會發生因轉(zhuan)動(dong)而帶來的磨損、老化問題(ti)，靈敏度高，啟動(dong)風(feng)(feng)速(su)為零(ling)，測量速(su)度快等。不(bu)同于機械式(shi)風(feng)(feng)傳感(gan)器(qi)的使用(yong)12個月或更短時(shi)間需校(xiao)準維護，超(chao)聲波風(feng)(feng)傳感(gan)器(qi)可以承受更長時(shi)間的工作期，不(bu)易遭受雨、霧、風(feng)(feng)沙影響及其他環境危害，維護成(cheng)本(ben)更低。

　　應用領域有城市(shi)環(huan)境(jing)(jing)、風力發電(dian)、氣象監(jian)測(ce)、橋梁隧(sui)道、航(hang)海(hai)船舶、航(hang)空機場、農(nong)業(ye)氣象、水利氣象、高速公路、電(dian)力環(huan)境(jing)(jing)……
