一、前言我们研制的电容式负荷传感器,其特性、原理、变换线路等已在计量技术85年第10期上作了论述,本文拟就该传感器实用结构设计和制造工艺等作一介绍。二、电容式负荷传感器的实用结构电容式负荷传感器的实用结构如图1所示,负荷通过承压头作用在弹性体的轮毂上侧,使轮辐发生挠曲。当额定负荷下的挠度y与轮辐厚度h之比y/h设计得较小时,负荷P与挠度y的变化可成较好的线性关系。电
I. Preface We have developed a capacitive load sensor, its characteristics, principles, such as conversion lines have been discussed in the measurement technology 85, No. 10, this paper is about the practical structure of the sensor design and manufacturing process to make an introduction. Second, the practical structure of the capacitive load sensor The practical structure of the capacitive load sensor shown in Figure 1, the load acting on the head of the elastic body through the pressure head, so that spoke deflection. When the ratio of the deflection y to the thickness h of the spokes at the rated load is designed to be small, the change of the load P and the deflection y may have a good linear relationship.
