Abstract

A resistance thermometer, composed of a plurality of components, at least comprising: at least one substrate, which is composed essentially of a material, whose thermal coefficient of expansion is essentially greater than 10.5 ppm/K; at least one resistive element, which is arranged on the substrate; and at least one electrically insulating, separating layer, which is arranged essentially between the resistive element and the substrate. The invention includes that the effective thermal coefficient of expansion TCEeff is greater than or equal to the thermal coefficient of expansion of the bulk metal of the resistive element.
