Abstract
A load measuring device for measuring a load acting on an elastically deformable member, has a distance sensor for measuring a length change in response to a deformation of the deformable member under a load. The sensor has a sensing element and a reference element arranged such that a portion of the elastically deformable member is interposed between the sensing element and the reference element. For paper manufacturing or finishing, two members between which the load is measured are cooperating rolls, at least one of which is provided with an elastic cover. One of the rolls includes the sensing element and the other roll includes the reference element. Alternatively, the two members are a roll and a cooperating belt, one having an elastic cover. Also, the sensing element and the reference element may be formed in one and the same member.
