A contour measuring devices for measuring the contour of hot-strip rolls installed in a roll stand during a rolling process includes a plurality of distance sensors that extend along the length of the hot-strip roll in a perpendicular and non-contacting manner and, in this manner. Each distance sensor has a measurement head oriented towards the hot-strip roll. The plurality of distance sensors are positioned separate from and lateral to each other on and along a longitudinal support. The longitudinal support is comprised of a double shell tube that cools the design sensors with an inner tube that conducts a coolant, a shell tube that surrounds the inner tube, and an annular space located therebetween. The inner tube is fixed at its opposite ends in a position relative to the shell tube.
