Abstract: The present invention relates to an arrangement (1) for measuring the temperature of a web. The arrangement (1) comprises a plurality of sensors (3) for contactless measuring of the temperature, an elongated housing (5) intended for extending essentially along a transverse direction (T) which is transverse to the direction of movement of a web. The sensors (3) are arranged in a chamber (6) within the housing (5) and spread along the front side (7a) of the housing (5). Each sensor (3) is connected to a data bus (9) for providing information of the measured temperature to other systems and/or apparatuses. The sensors (3) are attached to a support structure (19) having at least one rotatable shaft (23) in the interior of the housing (7), and wherein the shaft (23) is arranged to rotate the support structure (19) such that the sensors (3) are displaced to a calibration and/or protection position away from the openings (11) for calibration and/or protection of the sensors (3).

Abstract: The present invention relates to a process for controlling the temperature of a product in the form of a web (12) that is influenced by an IR ramp (9) for surface treatment of the web (12). With the help of a number of temperature sensors (26), the temperature of the web (12) is measured continuously within evenly distributed zones across and along its direction of movement (28), and the values obtained from the respective zone of the web (12) are transmitted to the respective drier modules (2) for the purpose of subjecting the aforementioned zones of the web to heat. The invention also relates to an arrangement with which the aforementioned process is executed.
