Abstract:

In the proposed flaw detector the principle of comparison of two articles of the same type the tested and the standard is used for checking two symmetrically placed surfaces of one item with the aid of two differentially connected-up pickups. A defect on one of the two simultaneously checked surfaces creates an imbalance in the voltages in the differential scheme of connecting in the pickups causing the needle of the checking instrument to deviate. The direction of the deviation of the needle indicates which of the checked surfaces has a flaw.
