The utility model discloses an EPS torque sensor adopting a strain gauge mode to detect torque, and belongs to the technical field of EPS torque sensors. The utility model relates to an EPS torque sensor for detecting torque by adopting a strain gauge mode, which comprises a torque transmission shaft and an outer shell, wherein the outer shell is arranged in the middle of the torque transmission shaft and wraps the periphery of the torque transmission shaft; a PCB (Printed Circuit Board) is coaxially arranged in the outer shell, and a socket is connected to the PCB; strain gauges are symmetrically arranged on the outer surface of a cylinder in the middle of the torque transmission shaft in the circumferential direction, and when the torque transmission shaft is subjected to torsion from asteering wheel, the strain gauges deform to generate a voltage signal; the strain gauges are used for collecting torque signals, so that the torque value precision is high, and the tested torque rangeis large, namely the outp
