Abstract : This paper introduces a new kind of torque sensor based on simple structure and high measuring accuracy ———the measuring system of grating torque sensors. It mainly presents the construction of grating torque sensors and the basic composing and working principles for the torque measuring system of grating torque sensors. It also discusses the mechanical errors that a grating torque sensor does and presents the electrical errors as well as the causes for both. It presents two methods for eliminating these errors : the digi2
tal filter method and the non2linearity compensating method. The experimentation results of the model system show the measuring accuracy of the grating torque system is as good as that of an electromagnetic torque sen2 sor. It proves that the new system is an ideal , static and dynamic measuring tool for average torque. It has practical value and has the potential to be spread and used.
Key words : grating torque sensor ; measuring system; measuring accuracy
