METHOD FOR THE IN-SITU CALIBRATION OF A THERMOMETER
A method for in-situ calibration and validation of a thermometer includes at least one of detecting and registering at least one measured value obtained by a temperature sensor and at least one characteristic physical or chemical reference variable of the reference element. The occurrence of a phase transformation of the reference element is detected. The point in time at which the phase transformation occurs is ascertained and a sensor temperature is obtained. The sensor temperature and the phase transformation temperature are compared using a model of dynamic heat flow for determining the difference between the sensor temperature and the phase transformation temperature. The model takes into consideration an inhomogeneous and/or dynamic movement of heat within the thermometer, thus at the site of the temperature sensor and/or at the site of the reference element and/or effects of heat removal, as brought about by changes in the ambient temperature.
