Abstract:
An electrical temperature sensor comprising: a platinum-containing resistance layer (1) as a measuring resistor provided with electrical connections on an electrically insulating surface of a ceramic substrate (2), wherein the resistance layer (1) is provided with at least one layer for protection against contamination or damage, wherein at least one intermediate layer (10) is applied on the resistance layer (1) as a diffusion barrier layer, and wherein an electrode (4) is provided on a side of the resistance layer (1) facing away from the substrate surface and spaced therefrom, wherein the electrode (4) is applied on a carrier substrate (12) lying opposite it and spaced from the resistance layer (1), and wherein the electrode (4) covers a supply line (15) to the resistance layer (1), the supply line (15) being mounted on the carrier substrate (12).
