The product has an outer diameter of Φ 61mm and a height of 10mm. At a rated range of 30Nm, its repeatability, nonlinearity, and hysteresis performance can be controlled within the range of 0.5% F.S. When subjected to lateral torsional loads, the maximum rated bending moment of the sensor is 20 Nm, the torsional stiffness is maintained within 57 kNm/Rad, and the maximum torsional angle does not exceed 0.04 °. When the sensor is subjected to lateral loads, the maximum load rating is 4.2 kN; in the direction of the sensor bearing axis, the load limit rating is 2.5 kN. If the lateral ultimate bending moment, lateral ultimate load, or axial ultimate load exceeds these ratings, the sensor structure will face the risk of damage or instability.
