Problems solved by technology

The disadvantage is the need for a free field of view, usually several meters, and therefore cannot be placed in confined spaces, which is often the case for paper machines
Additionally, the environment in which temperature measurements are taken can be harsh, including high temperatures and dirty conditions

Embodiment Construction

[0037] The front side of the device is defined as the side facing the surface for temperature measurement.

[0038] figure 1 shows a perspective front view of a device 1 according to an embodiment of the invention, figure 2 shows a top view of a device 1 according to an embodiment of the invention, image 3 A side view of a device 1 according to an embodiment of the invention is shown. The device 1 for measuring the temperature of a web comprises a plurality of sensors 3 for measuring said temperature without contact (hereinafter based on Figure 4 for a more detailed view and description). The device also comprises an elongated housing 5 for extending substantially in a direction T transverse to the direction of travel of the web. When the housing is fixedly mounted relative to the web, the distance between the sensor for measuring the temperature of the web and the web may be in the range of about 20mm to about 200mm, suitably in the range of about 50mm to about 100mm. ...

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).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.

Description

technical field [0001] The invention relates to a device for measuring the temperature of a web, the invention also relates to a method, a computer program, a computer readable medium and a control unit for measuring the temperature of a web. Background technique [0002] The invention is advantageously used for measuring the temperature of a web, such as paper, metal sheet or textile. [0003] Information about the temperature of the web is an important process parameter when producing materials in web form, such as paper, metal sheets, textiles, etc. Typically during the manufacturing process, the temperature is varied continuously along and across the web. Typically, these materials must themselves be dried or coated by some form of coating, dyeing or dipping that requires drying. Sometimes materials in web form must be heated to a certain temperature to cure or otherwise react. Other situations where temperature information is important relate to the pressing of paper...
