德國易福門IFM位移傳感器 (一)IFM機(jī)械振動偵測電子位移傳感器典型應(yīng)用電路 機(jī)械振動偵測電子傳感器一般由機(jī)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(guān)(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(jī)電路由機(jī)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(jī)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(dāng)汽 車受到振動時,B將機(jī)械能轉(zhuǎn)換為微弱的電信號,經(jīng)U1(HAl7358或LM358)的A運(yùn)放組成的電壓放大器U1A進(jìn)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?fàn)顟B(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(dāng)B檢測拾取到機(jī)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(dǎo)通,其集電極電壓(U1B的⑥腳電壓)降低,當(dāng)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?dǎo)通,其集電極變?yōu)榈碗娖?,相?dāng)于輸出一個低電平。同時,由于VDl的負(fù)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(yīng)。它是把被測量如位移等,轉(zhuǎn)換為電感量變化的一種裝置。按照轉(zhuǎn)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。 IFM自感型傳感器1. 可變磁阻式傳感器 可變磁阻式傳感器自感 自感L與氣隙δ成反比,而與氣隙導(dǎo)磁截面積S0 成正比。 | S0 固 定 不 變 , δ 變 化 時 | 德國IFM易福門電感式傳感器的工作原理 L 與δ呈非線性(雙曲線)關(guān)系。傳感器的靈敏度為 (9.21)靈敏度S與氣隙長度δ的平方成反比,δ愈小,靈敏度S愈高。為了減小非線性誤差,在實(shí)際應(yīng)用中,一般取 。這種傳感器適用于較小位移的測量,一般約為0.001~1 mm。 | δ 固 定 不 變 , S0 變 化 時 | 自感L與S0 呈線性關(guān)系。這種傳感器靈敏度較低。 |
