FAC series Crack detection gauge
This gauge is designed to measure the progress (length) of a crack and its rate of growth in a metal specimen. This gauge is bonded to the location where the generation of crack is predetermined. The grids of the gauge which are aligned with interval of 0.5mm are disconnected one by one by the progress of the crack. This gauge is used together with the crack gauge adaptor CGA-120A and the disconnection of one grid is measured as the change of 50×10-6 strain by strain meter.
