<P>PROBLEM TO BE SOLVED: To accurately measure load acting between an outer ring 1 and a hub 2 regardless of temperature changes. <P>SOLUTION: The load is computed on the basis of variations in the distances between displacement measuring elements 16a and 16b each provided for displacement sensors 11b and 11b and a ring to be detected 12a. A temperature sensor 21 is provided adjacently to the displacement-side measuring elements 16a and 16b. A detection signal of the temperature sensor 21 is inputted with detection signals of the displacement-side measuring elements 16a and 16b to a computing unit for computing the load. With temperature drifts in the detection signals of the displacement-side measuring elements 16a and 16b removed on the basis of the detection signal of the temperature sensor 21, the computing unit computes the load. As a result, it is possible to accurately measure the load acting between the outer ring 1 and the hub 2. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
