Abstract
The present disclosure relates to a device for determining a temperature of a liquid. The device comprises a first temperature sensor and a reference element. The reference element is composed of a material in which a phase transformation occurs at a predetermined temperature within a temperature range relevant for operation of the device. The material remains in the solid phase. Arranged on the reference element are a first and a second electrode electrically insulated from one another. The device includes a first connection line for contacting the first electrode, and a second connection line for contacting the second electrode. The device further includes a third connection line composed of a material different from the material of the first or the second connection line. The third connection line forms with the first or the second connection line the first temperature sensor in the form of a first thermocouple.
