Title: Manfred Kreuzer: Innovator in Optical Strain Gauges
Introduction
Manfred Kreuzer is a notable inventor based in Weiterstadt, Germany. He has made significant contributions to the field of optical strain measurement, holding a total of four patents. His work focuses on the development of advanced optical strain gauges that utilize fiber Bragg gratings.
Latest Patents
Kreuzer's latest patents include an innovative optical strain gauge that comprises a fiber Bragg grating. This invention relates to an optical strain gauge using a glass fiber that is coated with a sheath of polyether ether ketone. The sheath contains an admixture of at least 10 weight percent and a maximum of 40 weight percent of an inorganic filler, with a particle size ranging from 0.08 µm to 12 µm. The outer diameter of the sheath is between 0.2 mm and 1.2 mm, and the ratio between the outer diameter of the sheath and the diameter of the glass fiber is between 2 and 6. The design ensures that there is essentially no relative movement between the glass fiber and the sheath, enhancing the gauge's accuracy.
Another patent focuses on an optical strain gauge that incorporates an optical waveguide or fiber with a sensing section featuring a fiber Bragg grating. This design is intended for detecting strain in a strainable member on which the strain gauge is mounted. The optical waveguide is secured by two fastening elements that ensure a force-transmitting connection to the strainable member. A relatively soft elastic fixing material surrounds the optical waveguide, providing a form-fitting and force-isolating fixation of the fiber Bragg grating section.
