To provide a sensor-roll calibration device which can be used on-line, set the center position of a weight at the center position of a rotor easily in a short time, adjust the weight load with ease and good operability so that it passes through the center of the rotor at right angles, and hold constant a test load with high reproducibility without disturbance load.
This sensor-roll calibration device comprises a horizontal rail 12 installed along the axis Z of and on the top of a sensor roll; a truck 14 supported on the horizontal rail and movable along the axis; and a weight 16 suspended from the truck. The weight 16 has four vertical planes 16a, 16b surrounding a centerline passing its center of gravity, G, and a hanging part 17 provided on the centerline. The truck 14 has guide rollers 15a, 15b to guide the four vertical planes at right angles, a hanging metal fitting 18 engaged with the hanging part to raise and lower it, and a lift 19 for raising and lowering the hanging metal fitting. Lowering the hanging metal fitting causes only the weight 16 to be placed on the rotor 2, disengaging the hanging part from the hanging metal fitting.
