  • Sensor for expansion measurement
    Patent number: 5616847
    Abstract: A sensor which can be held around a cylindrical body has elastic parts which have expansion-sensitive elements on the inner surfaces. The elastic parts are pressed against the cylinder surface under high pressure by bracing the two sensor halves, such that the expansion-sensitive elements engage the cylinder surface by friction force and thus can detect the surface expansion occurring.The expansion-sensitive elements are protected against mechanical influences. Thus expansion measurement strips can be applied to the cylinder surface without adhesive and can be used several times.
