Abstract: The invention provides a high-precision strain type torque sensor which comprises two changeover plates (1), four strain columns (2), strain pieces (3), a dynamic strain meter (4) and a data acquisition and processing system (5). The four strain columns (2) and the upper and the lower changeover plates (1) are fixed. The strain columns (2) are of square column structures, each strain column is provided with two semi-circular grooves, the strain pieces (3) are pasted on the backs, above the semi-circular grooves, of the two symmetrical strain columns (2), and the four strain pieces (3) are pasted totally. In the testing process, one changeover plate (1) is fixed, a vibration source is arranged in the center of the other changeover plate (1), and four kinds of strain generated by the four strain pieces (2) form a full-bridge. The dynamic strain meter (4) converts the strain generated by the strain pieces (3) into dynamic voltage signals. The data acquisition and processing system (5) collects the dynamic voltage signals, and torque is obtained according to the dynamic voltage signals.
