Torque sensor based on ring ball gratings is composed of a special spheric grid annulus and a magnetic - electric detector. It has the characteristics of being shakeproof , waterproof, dustproof, greaseproof, and high sensitivity. We make some improvement on original torque sensor based on ring ball gratings, increasing the number of electromagnetic detector, and simplifying the signal processing process. First, we introduce the structure and principle of the improved sensor. Second, we establish the mathematical model of the improved sensor. Finally, we use ANSOFF for the modeling and elec- tromagnetic analysis of the improved sensor. And we use the improved sensor to measure torque in lab. The experiment data prove that the improved sensor can work normally and guarantee precision in bad environment.
