FBM216端子P0916BX FBM216端子P0916BX噪聲傳感器的工作原理 噪聲傳感器內置一個對聲音敏感的電容式駐極體話筒，駐極體面與背電極相對，中間有一個極小的空氣隙，形成一個以空氣隙和駐極體作絕緣介質，以背電極和駐極體上的金屬層作為兩個電極構成一個平板電容器。電容的兩極之間有輸出電極。由于駐極體薄膜上分布有自由電荷。當聲波引起駐極體薄膜振動而產生位移時；改變了電容兩極版之間的距離，從而引起電容的容量發生變化，由于駐極體上的電荷數始終保持恒定，根據公式：Q＝CU，所以當C變化時必然引起電容器兩端電壓U的變化，從而輸出電信號，實現聲音信號到電信號的變換。 具體來說，駐極體總的電荷量是不變，當極板在聲波壓力下后退時，電容量減小，電容兩極間的電壓就會成反比的升高，反之電容量增加時電容兩極間的電壓就會成反比的降低。再通過阻抗非常高的場效應將電容兩端的電壓取出來，噪聲傳感器同時進行放大，從而可以得到和聲音對應的電壓了。由于場效應管時有源器件，需要一定的偏置和電流才可以工作在放大狀態，因此，駐極體話筒都要加一個直流偏置才能工作。
噪聲傳感器RS－ZS－N01－＊是一款高精度的聲音計量儀器，產品采用高靈敏度的電容式麥克風，信號穩定，精度高。具有測量范圍寬、線形度好、使用方便、便于安裝、傳輸距離遠等特點。量程高達30dB～120dB，滿足日常測量需求，廣泛應用于家庭、辦公、車間、汽車測量、工業測量等各種領域。 從世界衛生組織發布的報告可看出，噪音污染已經成為僅次于空氣污染之后威脅公民健康的隱患，這比此前想象的情形更為嚴重。隨著城市規劃的失衡很多城市噪音污染仍然無法得到很好的控制，但相信在科技力量幫助之可以讓噪音的危害降得越來越低。
