/> </div><div>　　消防五參數風速儀的技術原理：<br /> </div><div>　　消防五參數風速儀是利用超聲波時差法來實現風速的測量。聲音在空氣中的傳播速度，會和風向上的氣流速度疊加。若超聲波的傳播方向與風向相同，它的速度會加快；反之，若超聲波的傳播方向若與風向相反，它的速度會變慢。因此，在固定的檢測條件下，超聲波在空氣中傳播的速度可以和風速函數對應。通過計算即可得到的風速和風向。由于聲波在空氣中傳播時，它的速度受溫度的影響很大；本風速儀檢測兩個通道上的兩個相反方向，因此溫度對聲波速度產生的影響可以忽略不計。<br /> </div><div>　　消防五參數風速儀是對傳統風杯/風向標/螺旋槳風速風向傳感器的替代產品。它揉合了的超聲波制造的專業技術，是基于現有的、高度成功的、實踐證明的超聲波技術。適用于陸地和海洋環境。有別于傳統易損壞的風杯/風向標/螺旋槳風速風向傳感器，超聲波風速風向儀質量輕，其堅固的高強度結構設計在安裝和使用時無需擔心損壞。</div> </div> <div id="vxxthb5"
