德國易福門IFM位移傳感器

（一）IFM機械振動偵測電子位移傳感器典型應用電路

 機械振動偵測電子傳感器一般由機械振動偵測換能器件、交流電壓放大器、電壓比較器、電子開關（或電平變換）等電路組成。

 汽車防盜系統(tǒng)用電子振動傳感器電路原理圖，整機電路由機械振動檢測、電壓放大器、電壓比較器、電平變換電路等組成。

 B 為機械振動能拾取元件，是在直徑20mm的壓電陶瓷片上加焊一段長度為20mm的螺旋狀彈簧。其作用是既提高了振動靈敏度又抑制了音頻信號的誤觸發(fā)。當汽 車受到振動時，B將機械能轉換為微弱的電信號，經(jīng)U1（HAl7358或LM358）的A運放組成的電壓放大器U1A進行放大后，從①腳輸出，經(jīng)R12、 R4加在VI的基極。在這里，R12、1{4組成了V1的靜態(tài)偏置電路，調(diào)整R12的阻值，可以調(diào)整傳感器的檢測靈敏度。在平時，V1在截止狀態(tài)，其集電 極為高電平（約為電源電壓），即電壓比較器U1B的反相輸入端⑥腳為電源電壓，由于其同相輸入端⑤腳的電壓為R5與R6分壓后獲得，此時⑥腳電壓高于⑤腳 電壓，電壓比較器U1B的⑦腳輸出低電平，V2截止，其集電極為高電平，傳感器沒有輸出。

 當B檢測拾取到機械振動能時，U1A輸出幅度較大的交 流信號，經(jīng)R12、R4加在V1的基極，其交流信號的正半周使VI導通，其集電極電壓（U1B的⑥腳電壓）降低，當U1B的⑥腳電壓低于⑤腳電壓時，⑦腳 輸出高電平，V2由截止變?yōu)閷?，其集電極變?yōu)榈碗娖?，相當于輸出一個低電平。同時，由于VDl的負極電位變低，有電流經(jīng)過R9、VDl，VDl發(fā)光，作 傳感器工作有效指示。

ifm易福門電感式傳感器的工作原理是電磁感應。它是把被測量如位移等，轉換為電感量變化的一種裝置。按照轉換方式的不同，可分為自感式（包括可變磁阻式與渦流式）和互感式（差動變壓器式）兩種。
