Abstract
A device for contact-free measurement of the temperature at the surface of a workpiece, in particular aluminum strips and sections, and/or for determining and/or measuring the shape of a workpiece, in particular dimension or shape or the like includes, a measuring pin which has a central bore resides in a housing and is directed at the workpiece. The workpiece is jetted with compressed gas emerging from the central bore. The measuring pin in the housing can be moved in the direction x and maintains a specific distance s from the surface of the workpiece as a result of a negative pressure created by the compressed gas between the base of the measuring pin and the workpiece surface. Situated in the bore and at the base of the measuring pin are thermocouples which transmit their measured values to a registering unit.
