Abstract

The invention relates to a force sensor for measuring a bearing force of a roller deviating a web of material. The force sensor includes a base element on which at least one sensor element is supported. The sensor element has at least one plate which can be elastically deformed by the bearing force and is provided with at least one force transducer. The sensor element is loaded by a pressure piece into which the bearing force is introduced by means of a spring. The spring has a larger range of spring—in the direction of the force—than the elastically deformable plate for the same load. In order to limit the action of the force on the sensor element, an annular abutment is provided, against which the pressure piece can be pressed flat. The abutment is provided around the sensor element.
