a) 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). The invention also relates to a method for measuring the temperature of a web, a computer program, a computer readable medium and a control unit.

Abrégé

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).The invention also relates to a method for measuring the temperature of a web, a computer program, a computer readable medium and a control unit.
