Abstract
A measuring device for arranging in tubular cavities of machine elements has a deformation body with a deformation region. A respective press-in ring element is secured to two opposite ends of the deformation body. The deformation body can be introduced into a tubular cavity of a machine element through a press-in opening using a press-in force such that mechanical effects acting on the machine element can extend to the deformation region by the press-in ring elements and can be detected by a sensor secured to the deformation region. The press-in ring elements have a ring element thickness that is so low that the deformation body can be reliably introduced into the tubular cavity and can be stored therein in a force-fitting manner while the cavity circumference of the tubular cavity is designed to have a non-circular shape, or has high tolerance variations, such as those found in pipes for example.
