In the housing, leads of the cable are connected to the self-supporting electrical conductors. Using bed profiles passing through the cover, the film resistors are spaced from the housing sufficiently far that the film resistors and the housing are largely thermally decoupled. As an intermediate product, a measurement tip or a sensor bar as part of a sensor tip is made of purely inorganic components, in order to make the mass production efficient.
