Abstract: A method for measuring side run-out of a wheel by turning the wheel mounted on a roller supported rotatably. It is judged whether or not the difference between the side run-out of a wheel at the start point onf one turn and the end point of one turn falls within a specified range or not. If it falls within the specified range, the difference between the maximum and minimum values of the side run-out during rotation is defined as the side run-out of the wheel. Even if the wheel is displaced during measurement to cause variation in the measurement value of the side run-out, the varied measurement value can be removed and highly accurate side run-out and side run-out width can be obtained.

Abstract: To compensate for modules which expand as a function of temperature, the present invention provides for using a flat sensor having special structural components that feature temperature-dependent electrical conductivity over the entire length to be measured. The benefit derived is that the temperature is measured over the entire sensor. The structural components are interconnected into tracks, and linked to electronics integrated on the sensor. On its rear side, the sensor has an adhesive layer, enabling it to be simply adhesively mounted on the component to be measured. The manner in which the structural components are distributed, makes it possible to adjust the sensor to any desired length, simply by trimming it. After the sensor is mounted, a protective layer is adhesively applied thereto, as a protective measure.
