寶德8020型插入式渦輪流量傳感器/BURKERT流量傳感器
寶德8020型插入式渦輪流量傳感器的結(jié)構(gòu)和工作原理如圖 11所示。在進(jìn)氣管道正中間設(shè)有*線形或三角形的渦流發(fā)生器，當(dāng)空氣流經(jīng)該渦流發(fā)生器時(shí)，在其后部的氣流中會(huì)不斷產(chǎn)生列不對(duì)稱卻十分規(guī)則的被稱為卡門渦流的空氣渦流。根據(jù)卡門渦流理論，這個(gè)旋渦行列是紊亂地依次沿氣流流動(dòng)方向移動(dòng)，其移動(dòng)的速度與空氣流速成正比，即在單位時(shí)間內(nèi)通過渦流發(fā)生器后方某點(diǎn)的旋渦數(shù)量與空氣流速成正比。因此，通過測(cè)量單位時(shí)間內(nèi)渦流的數(shù)量就可計(jì)算出空氣流速和流量。測(cè)量單位時(shí)間內(nèi)旋渦數(shù)量的方法有反光鏡檢出式和超聲波檢出式兩種。圖 12所示是反光鏡檢出式卡門渦旋流量傳感器，其內(nèi)有只發(fā)光二極管和只光敏三極管。發(fā)光二極管發(fā)出的光束被片反光鏡反射到光敏三極管上，使光敏三極管導(dǎo)通。反光鏡安裝在個(gè)很薄的金屬簧片上。金屬簧片在進(jìn)氣氣流旋渦的壓力作用下產(chǎn)生振動(dòng)，其振動(dòng)頻率與單位時(shí)間內(nèi)產(chǎn)生的旋渦數(shù)量相同。由于反光鏡隨簧片同振動(dòng)，因此被反射的光束也以相同的頻率變化，致使光敏三極管也隨光束以同樣的頻率導(dǎo)通、截止。ECU根據(jù)光敏三極管導(dǎo)通、截止的頻率即可計(jì)算出進(jìn)氣量（圖 11）。凌志LS400小轎車即用了這種型式的卡門渦旋式空氣流量傳感器。
