Abstract

The invention relates to an apparatus and a method for monitoring the state of a machine element (10) in a paper machine or finishing machine for paper. The apparatus comprises a magnetized conductor (20), for example a copper fiber coated with a magnetic materiel. The conductor (20) can be placed in a rotating machine element (10), such as a roll or the like, wherein the element in contact with the roll surface produces pressure in the conductor (20), as well as an electrical signal corresponding to the pressure. The magnetized conductor (20) can be advantageously arranged as a loop-shaped measurement sensor, wherein several of these sensors can be placed in different sections of the machine element (10). The variable measured by the sensors is transmitted forward as an electrical signal.
