Other Title
Process and device for the monitoring of the occurrence or propagation of fractures or cracks in materials, workpieces, components, structures or celestial bodies, in particular in earthquake-hazard areas or rock movement in tunnel construction
Abstract
A process and device for monitoring the occurrence of cracks, fractures, earthquakes and movement of strata is based on the principle that events of this sort are associated with electrical field changes. The electrical field changes associated with the occurrence of events of this sort are recorded by a field probe (1) which has metallic probe elements (2, 3) which supply a differential amplifier (5) whose output signal (6) supplies an analyzer (10, 11).
