- Abstract:
- In order to obtain accurate torque measurements in harsh condition, such as underwater, a torque transducer based on fiber Bragg grating is proposed in this paper. According to optimized deformation element design and fiber Bragg grating patching tactic, the new proposed torque transducer realizes accurate torque detection with automatic compensations of temperature and bending moment as well as avoiding influences from environment. The accuracy of the torque transducer, as well as its underwater performance are tested by calibration tests both in air and in underwater environment, indicating the designed torque transducer is not only able to realize high- accurate measurements, but also can be applied in torque sensing in underwater environment.
