摘要

Measuring roller for determining variations in flatness of a band-shaped material, wherein the measuring roller has a longitudinal axis and at least one in a recess in the measuring roll, the sensor arranged in a from one to the outer surface of the measuring roll force introduced can generate a measurement signal, with a first temperature sensor, which in a first distance in the radial direction is arranged at a distance from the longitudinal axis, and a second temperature sensor in a second, different distance from the first distance in the radial direction from the longitudinal axis is arranged at a distance of.
