ABSTRACT:
An inclination detector device is disclosed. The detector device has a light source, a light sensor device, and a level arranged between the light source and the light sensor device. In addition, a light guide is arranged between the light source and the level. The light source is joined to the light guide, the light guide is joined to the level, and the level is joined to the light sensor device in such a way that the light source, the light guide, the level, and the light sensor device form a closed unit.
