A tube bundle reactor carries out endothermic or exothermic gas phase reactions. The tube bundle of reactor tubes are filled with catalyst, and have their ends fastened tightly in tube sheets (3, 4). A fluid heat carrier (10) flows around the tubes during operation. A shell (5) encloses the tube bundle. A gas inlet head (6) spans one of the tube sheets, and a gas outlet head (7) spans the other tube sheet. The reactor tubes are in fluid communication with the gas inlet and outlet heads (6, 7), and further include at least one stage thermometer (9) installed in a thermometer tube (2) disposed in the tube bundle. The at least one stage thermometer (9) is axially movable inside the thermometer tube (2), and the tube bundle reactor (1) includes a mechanical positioning means (8) to effect the axial movement of the stage thermometer (9). Moreover, a method is proposed for measuring a temperature profile in tube bundle reactors of the kind specified.
