第3章 压电式传感器
从晶体上沿着轴线切下的一片压电元件称为压电晶片,当晶片在沿X 轴方向有作用力Fx作用时,会在与X轴方向垂直的表面产生电荷,其大小 为: q x d11Fx (电荷极性由力的方向决定)
当晶片在沿Y轴方向有作用力Fy作用时,会在与Y轴方向垂直的表面产 生电荷,其大小为: q y d11 a Fy (电荷极性由力的方向决定) b L 从以上两式可以看出,纵向压电效应与元件尺寸无关,而横向压电效 应与元件尺寸有关;且从式中的负号可以看出,两者产生电荷的极性相反。 综上所述,晶体切片上电荷的符号与受力方向的关系可用图3-2表示。

图3-12是一种振动加速度传感器的测量电路。电路中,利用传感 器将被测加速度转换成电压输出,经过运放741和阻容元件组成的二 阶低通滤波器将53Hz以上的振荡频率衰减,再经IC2(3521)和阻容元 件组成的高通滤波器滤去低于1Hz的振荡频率。IC3与IC4组成交流放大 积分器,可以将IC2的输出转换成速度输出。IC5与IC6又可以将速度积 分成位移输出。由于加速度、速度、位移幅度的不同,为了都能送至 同一片MC14433做A/D转换,电路中配备了未标阻值的三个串联分压器, 可以根据需要设计选择。图中IC7是反相器。

综上所述,螺管式自感传感器的特点: ①结构简单,制造装配容易; ②由于空气间隙大,磁路的磁阻高,因此灵敏度低 ,但线性范围大; ③由于磁路大部分为空气,易受外部磁场干扰; ④由于磁阻高,为了达到某一自感量,需要的线圈 匝数多,因而线圈分布电容大; ⑤要求线圈框架尺寸和形状必须稳定,否则影响其 线性和稳定性。

第6章 电感式传感器
电感式传感器是建立在电磁感应基础上,利用 线圈自感或互感的改变来实现测量的一种装置。它 可对直线位移和角位移进行直接测量,也可通过一 定的敏感元件把振动、压力、应变、流量等转换成 位移量而进行测量。通常可由下列方法使线圈的电 感变化:
(1)改变几何形状; (2)改变磁路的磁阻; (3)改变磁芯材料的导磁率; (4)改变一组线圈的两部分或几部分间的耦合度。
