摘要

FIELD: measuring devices. SUBSTANCE: nondestructive inspection of physical and mechanical properties of materials is based on measuring the recoil distance of balls. Installation comprises holder 10 of specimen 11, device 3 disposed above holder for dropping of balls and comprising hopper 5 and cut-off retainer 7, and apparatuses for measuring recoil range of balls 4. Said apparatuses have electric-contact device 16 arranged along ball recoil trajectory, and digital indication unit with two indicators connected with said device 16. Electric-contact device comprises groups of activated and interrogated buses combined, jointly with indicators, into an electric circuit comprising interlocking device 18, overfilling meters and multiplexers which ensures automatic location of all drop point coordinates. EFFECT: improved design. 2 dwg
