在研究液压系统和元件时,电学的或电子学的测量方法得到了广泛的应用。这是因为电测的方法能方便地把机械量如位移、速度、加速度、力、力矩、压力、温度等转换成电的信号。电信号可以远传、灵敏度高、易于切换、响应频率高,并可贮存和用计算机进行数据处理。本讲对电测方法作些介 In the study of hydraulic systems and components, electrical or electronic measurement methods have been widely used. This is because electrical measurement methods can easily convert mechanical quantities such as displacement, velocity, acceleration, force, torque, pressure, temperature, etc. into electrical signals. Electrical signals can be remote, high sensitivity, easy to switch, high response frequency, and can store and use computer data processing. This talk about the electrical measurement method for some mediated
