Abstract (en)
[origin: WO2012080010A1] The invention relates to a device for determining the weight per unit area of a moving material web (6), in particular a fibrous material web, said device comprising at least one microwave sensor that has an element for coupling the microwaves (8) and a reference element (9), the coupling element (8) and the reference element (9) being located at a distance from one another in such a way that the material web (6) can be moved therebetween. At least one microwave sensor element, the coupling element (8) and/or the reference element (9) can be moved such that the distances (a, b) between the material web (6) and the elements (8, 9) can be adjusted for or during the measurement of the moving material web.
