Bestimmung der Schräglage von Rissen bei der Risstiefenmessung

A pocket size digital crack depth gage based on the potential drop method was presented earlier, which monitors the crack size along its growth direction. This value may yield overestimation of necessary repair in case of crack orientations not perpendicular to the surface. Therefore, an additional function was introduced to the new version of this equipment to determine the angle of inclination of the crack relative to the surface. This function allows to measure the projection of the crack depth perpendicular to the surface.
