Abstract

The present disclosure relates to a device for determining and/or monitoring the temperature of a medium, comprising a temperature sensor with a temperature-sensitive sensor element which is placed in electrical contact by means of at least a first connection line and a second connection line, wherein the first connection line is divided into a first section and a second section, wherein the first section which faces the sensor element is composed of a first material, and wherein the second section which faces away from the sensor element is composed of a second material which differs from the first material, wherein the second connection line is composed of the second material, and wherein the first section of the first connection line and at least one part of the second connection line form a first difference temperature sensor in the form of a thermocouple.
