Bonded to a cracked or crack-expected part of structures and materials, the KV series gages 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)
Features
- Progress and developing velocity of a crack are electrically obtained.
- High response speed.
- Applicable to both flat and curved surfaces.
- Resistance change vs crack length is virtually linear.
- Dedicated adapter enables use of conventional strain ampli?ers.
- Extremely simple and convenient compared with the conventional optical method.
- 2 trigger wires each before and behind the grids (KV-5C) can be used for automation of measurement.
