Abstract
The present disclosure relates to a device for determining and/or monitoring temperature of a liquid, comprising a temperature sensor, a reference element for in-situ calibration and/or validation of a temperature sensor and an electronics unit, wherein the reference element is composed at least partially of a material, in the case of which at least one phase transformation occurs at at least a first predetermined phase transformation temperature in a temperature range relevant for calibrating the temperature sensor, in which phase transformation the material remains in the solid phase. According to the present disclosure, the electronics unit is embodied to supply the reference element with a dynamic excitation signal. Furthermore, the present disclosure relates to a method for calibration and/or validation of a temperature sensor based on a device of the invention.
