The invention relates to a path sensor which displays the position of a first body in relation to a second body by outputting a path signal. The path sensor is provided with a first component, which is coupled to the first body, and a second component, which is coupled to the second body. The second component comprises a thermal expansion coefficient which is different from a thermal expansion coefficient of the first component. A reference point is provided on the first component and the path signal is adapted by the position of the reference point in relation to the second component. The reference point of a predetermined central section of the second component is opposite a preferred position of the first body in relation to the second body. The second component is subsequently mechanically coupled to the second body via the predetermined section. |
