德国易福门IFM位移传感器

（一）IFM机械振动侦测电子位移传感器典型应用电路
 机械振动侦测电子传感器一般由机械振动侦测换能器件、交流电压放大器、电压比较器、电子开关（或电平变换）等电路组成。
 汽车防盗系统用电子振动传感器电路原理图，整机电路由机械振动检测、电压放大器、电压比较器、电平变换电路等组成。
 B 为机械振动能拾取元件，是在直径20mm的压电陶瓷片上加焊一段长度为20mm的螺旋状弹簧。其作用是既提高了振动灵敏度又抑制了音频信号的误触发。当汽 车受到振动时，B将机械能转换为微弱的电信号，经U1（HAl7358或LM358）的A运放组成的电压放大器U1A进行放大后，从①脚输出，经R12、 R4加在VI的基极。在这里，R12、1{4组成了V1的静态偏置电路，调整R12的阻值，可以调整传感器的检测灵敏度。在平时，V1在截止状态，其集电 极为高电平（约为电源电压），即电压比较器U1B的反相输入端⑥脚为电源电压，由于其同相输入端⑤脚的电压为R5与R6分压后获得，此时⑥脚电压高于⑤脚 电压，电压比较器U1B的⑦脚输出低电平，V2截止，其集电极为高电平，传感器没有输出。
 当B检测拾取到机械振动能时，U1A输出幅度较大的交 流信号，经R12、R4加在V1的基极，其交流信号的正半周使VI导通，其集电极电压（U1B的⑥脚电压）降低，当U1B的⑥脚电压低于⑤脚电压时，⑦脚 输出高电平，V2由截止变为导通，其集电极变为低电平，相当于输出一个低电平。同时，由于VDl的负极电位变低，有电流经过R9、VDl，VDl发光，作 传感器工作有效指示。

ifm易福门电感式传感器的工作原理是电磁感应。它是把被测量如位移等，转换为电感量变化的一种装置。按照转换方式的不同，可分为自感式（包括可变磁阻式与涡流式）和互感式（差动变压器式）两种。
