PURPOSE:To measure torque continuously, instantaneously and simply by processing signals outputted from a photoelectric element string interrupted from light rays radiated from a light source by the motion of an indicator fixed on a rotary shaft of a substance to be measured and calculating the torque by an arithmetic circuit in which the inertia moment and torque calculating equations of the substance to be measured have been previously stored. CONSTITUTION:When a second hand shaft 3 is rotated, a second hand body is moved to interrupt light rays 6 radiated from the light source 1 from the arrival at the photoe lectric element string 11. A line sensor camera 5 sends the passing positions of the second hand body 4 on the photoelectric element string 11 continuously as signals to an optomotion detector 7, where combines the positions and times required up to the positions and sends the combined results to a waveform storage device 8 to store the combined results temporally. A microcomputer 9 invokes data from the device 8 and converts the selected position into an angular acceleration on the basis of a previously stored operation program. In addition, the microcomputer 9 previously stores the inertia moments of the second hand body, the second hand shaft 3, a gear or the like fixed on the second hand shaft 3 and multiplies the angular acceleration by the inertia moment to output a graph formed by the torque and time. |
