Overview

Bonded to the cracked part of a structure or material (or a part of such material where a crack is predicted to develop), the KV series gages measure the developing length and velocity of the crack.
Different from usual strain gages, the grids of the KV series gages are cut along with crack development, resulting in resistance change.

Key Features

Progress and developing velocity of the crack are electrically obtained.

Applicable to both ?at and curved surfaces.

Resistance change vs crack length is virtually linear.

Dedicated adapter enables use of a conventional strain ampli?er.

Extremely simple and convenient compared with the conventional optical method.

Allows 2 trigger wires each in front of and behind the grid (KV-5C) to be used for automation of measurement.
