KV Series Crack Gages
Bonded to a cracked or crack-expected part of structures and materials, the KV Series Crack Gages/Gauges measure the developing length and velocity of the crack. Different from usual strain gages, the grids of KV series gages is cut along with crack development, resulting in resistance change. (Utility model). The main features of this series are progress and developing velocity of a crack are electrically obtained, they are applicable to both ﬂat and curved surfaces; the resistance change vs crack length is virtually linear. There is also dedicated adapter to enable the use of conventional strain ampliﬁers. They are extremely simple and convenient compared to the conventional optical method. The 2 trigger wires each before and behind the grids (KV-5C) can be used for automation of measurement.
