Abstract
A sealing strip and a sealing device for sealing a negative-pressure zone of a suction roller for a machine for producing or processing a fibrous web, such as a paper, board or tissue machine. The stealing strip has an upper face, which forms a sealing surface of the sealing strip, and the sealing strip includes a sensor unit, which has a first temperature sensor at a first distance from the sealing surface and a second temperature sensor at a second distance from the sealing surface. The first distance is smaller than the second distance. The sealing strip is formed of a base material and a protective material which is different from the base material, and the sensor unit is embedded, in particular cast, into the protective material.
