补充资料：电容式传感器
把被测的机械量，如位移、压力等转换为电容量变化的传感器。它的敏感部分就是具有可变参数的电容器。其最常用的形式是由两个平行电极组成、极间以空气为介质的电容器（见图）。若忽略边缘效应，平板电容器的电容为εA／δ，式中ε为极间介质的介电常数，A为两电极互相覆盖的有效面积,δ为两电极之间的距离。δ、A、ε 三个参数中任一个的变化都将引起电容量变化，并可用于测量。因此电容式传感器可分为极距变化型、面积变化型、介质变化型三类。极距变化型一般用来测量微小的线位移或由于力、压力、振动等引起的极距变化(见电容式压力传感器)。面积变化型一般用于测量角位移或较大的线位移。介质变化型常用于物位测量和各种介质的温度、密度、湿度的测定。电容器传感器的优点是结构简单,价格便宜，灵敏度高,过载能力强，动态响应特性好和对高温、辐射、强振等恶劣条件的适应性强等。缺点是输出有非线性，寄生电容和分布电容对灵敏度和测量精度的影响较大，以及联接电路较复杂等。70年代末以来,随着集成电路技术的发展,出现了与微型测量仪表封装在一起的电容式传感器。这种新型的传感器能使分布电容的影响大为减小，使其固有的缺点得到克服。电容式传感器是一种用途极广，很有发展潜力的传感器。
