A detection system for swing angle of dynamic torque loader magnetic yoke

With the progress of scientific technology and development of production, measurement technology of dynamic torque has been widely applied to lots of fields of national economy. In different fields, the measurement method of dynamic torque is not the same. This paper describes a method for measuring dynamic torque by swiveling angle of the magnetic yoke, designs and implements an acquisition system of dynamic torque. The system can achieve many functions, for example, it can collect 16-ways parallel digital signal, analyze and display oscillogram and so on, through analyze and process real-time oscillogram, we can measure the instantaneous value of swing angle, by which we can accurately obtain the instantaneous dynamic torque.
