硕士讨论生课程《智能传感器技术》(考查)自选课题2010 年 5 月 24 日 智能电容式传感器的国外现状与进展趋势The Current Situation And Tendency ofDyadic Intelligence Capacitance Sensor at Home and Aboard摘要电容式传感器是把被测量转换为电容量变化的一种传感器
它不但广泛应用于位移、振动、角度、加速度等机械量的精密测量,而且还逐步地扩大,应用于压力、液面、料面、成分含量等方面的测量
这种传感器具有结构简单、灵敏度高、动态响应特性好、适应性强、抗过载能力大与价格便宜等一系列优点,因此,占有很重要的地位
文中主要介绍了电容式感器的结构原理、性能改善、测量电路、应用与其进展
关键词电容式 智能化 测量电路AbstractCapacitive sensor is a sensor which convert the measurements into the change of capacitances
It is not only widely used in displacement,virbration,angle,acceration and other precision measurement of mechancial energy,but also gradually expanded,applied in pressure,surface,material surface,ingredients and other measurements
The sensor has a series of advantages such as simple structure,high sensitivity,good dynamic response,adaptability,
