RADIO-FREQUENCY CRACK DETECTOR
The crack detector was designed for the precise and rapid indication of the presence and depth of cracks and seams in ferrous and non-ferrous electrically-conducting materials. Its principal features are: the giving of a direct reading, high speed of testing, high speed of operation, adjustment and operation by unskilled staff after brief and elementary instruction; a breakdown indicator, which gives immediate warning if the automatic apparatus fails. The instrument indicates cracks from less than 0.001 in. up to 0.250 in. deep. The crack detector was developed primarily for testing wire and bar stock materials up to 36 in. diameter. Round, hexagonal, tubes, angles and channels, and variations of these shapes of material can also be monitored with special order head coils.
