Abstract

The cell has a full test tube (31) and an empty test tube (33) that are arranged above one another and are separated by an inter-test tube distance. A calculating unit determines overheating in a core for a given position of the core along a vertical axis, from a difference between temperature differences relative to the full and empty test tubes when the full test tube is situated at the position and the empty test tube is situated at the position consecutive to displacement of the cell at a distance equal to the inter-test tube distance, respectively.
