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.
An arrangement for measuring temperature of a web, the arrangement comprises a plurality of sensors for contactless measuring of the temperature, a housing intended for extending along a transverse direction (T) which is transverse to the direction of movement of the web, characterized in that the sensors are arranged in a chamber within the housing and spread along a front side of the housing, and that each sensor is connected to a data bus for providing information of the measured temperature to other systems and/or apparatuses, a plurality of openings are provided at the front side of the housing at positions for the sensors, such that each sensor is positioned adjacent to an opening, wherein the sensors are attached to a circuit board which is connected to the data bus, the sensors and the circuit board are attached to a support structure having at least one rotatable shaft in the interior of the housing, and wherein the shaft is arranged to rotate the support structure such that the sensors are displaced to a calibration and/or protection position away from the openings for calibration and/or protection of the sensors.
