Abstract: An apparatus for measuring a temperature distribution on a surface has a first plurality of conductors, which are each arranged parallel in relation to one another, and a second plurality of conductors, which are each arranged parallel in relation to one another. The apparatus further has a connection conductor, which is electrically conductively connected to a voltage source, and an evaluation unit. Each conductor of the first plurality of conductors crosses each conductor of the second plurality of conductors and each conductor of the first plurality of conductors is electrically isolated from each conductor of the second plurality of conductors.

Abstract: A heatable media guide serves for guiding a medium. It has a tubular guide element which extends in a longitudinal direction and has a sheathing made from a sheathing material, which surrounds an interior space for the medium. The guide element furthermore has at least one heating element, which extends with the sheathing in the longitudinal direction and which is embedded in the sheathing material.
