Patent number: 8474333Abstract: An industrial roll is provided, comprising a transverse force transducing fiber Bragg sensor that is embedded in the roll cover and/or located in-between the roll cover and the roll core of the industrial roll. The transverse force transducing fiber Bragg sensor comprises a fiber optical waveguide having a fiber core and a fiber cladding, and a stud element being nonpositively joined to a partial area of the circumferential surface of the fiber optical waveguide. The fiber optical waveguide comprises a Bragg grating located in the fiber core, whereby the dimension of the partial area in the longitudinal direction of the fiber is longer than a grating spacing of the Bragg grating. The partial area is located at a section of the fiber optical waveguide housing the Bragg grating, and at least a first component of the stud element is formed from a first material having a Young's modulus of less than 10 kN/mm2.Type: GrantFiled: March 23, 2011Date of Patent: July 2, 2013Assignee: Voith Patent GmbHInventors: Antje Berendes, Norbert Gamsjaeger, Wolfgang Ecke, Manfred Rothhardt
