A substrate for a sensor assembly of a resistance thermometer is disclosed. The substrate is comprised of spinel and magnesium oxide and has a thermal coefficient of expansion approximately equal to the thermal coefficient of expansion of platinum.

A substrate for a sensor assembly of a resistance thermometer is disclosed. The substrate has a plurality of first layers formed of a first material and a plurality of second layers formed of a second material. The first and second layers are disposed over one another such that a thermal coefficient of expansion of the substrate is approximately equal to the thermal coefficient of expansion of platinum.

A sensor assembly for a resistance thermometer is disclosed. The sensor assembly comprises a substrate, a measuring structure disposed on the substrate, and a cover layer disposed on the measuring structure. The cover layer has a plurality of first layers formed of a first material and a plurality of second layers formed of a second material. The first and second layers are disposed over one another such that a thermal coefficient of expansion of the cover layer is adapted to a thermal coefficient of expansion of the measuring structure.
