Abstract: Utilize the function of twain dimension microdisplacement for planar encoder, to establish a system of a group of measurement, to measure gigantic rotational shaft torque Sum up the principle, development and utilization of torque measurement. Measure the relatively rotation displacement of twain section using quadruplet planar encoder. By operation the relatively rotation displacement, the relatively rotation angle is gained, further realize torque measurement, realize dynamics observat`ion of main drive for large mechanism equipment, which can provide the foundation of the equipment automatiza-tion and intelligentization.

Key words: Dynamics observation, Larger rotation shaft, Measure torque, Planar encoder
