KWR61N30 torque sensor is a high-precision product that can output both analog and digital signals directly. This product can customize and adapt high-precision signal acquisition modules according to different signal output requirements (such as RS485, CAN signal output). 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. The applicable working temperature range of this product is between -10 ℃ and 80 ℃. Within this temperature range, the output of the sensor can remain stable and not be affected by temperature fluctuations. Beyond the temperature range, stability may be affected and the output signal may drift or fluctuate. This product has been verified through multiple practical tests, and the theoretical data is highly consistent with the actual data, demonstrating superior performance.
