Abstract: A system for changing a roller, has a system for determining parameters which characterize the identity and/or the operating state of a roller of an industrial plant, at least one sensor arranged on the roller for furnishing parameters being designed such that the furnished identity parameter of the roller is detectable, and a reading device designed for reading out detected parameters from the sensor without contact. The sensor is also designed to detect an operation state parameter of the roller and can be operated at a roller temperature of at least 150 C. In a rollerchanging wagon on which a roller can be mounted in such a manner that the roller can be guided into or out of a roll stand, the sensor is arranged on the roller for the purpose of furnishing and/or detecting parameters. The process security for an industrial plant can be increased by such a system.
