Abstract
FIELD: instruments for non-destructive testing of materials in civil engineering, scientific research and other applications. SUBSTANCE: indenter-acting instrument has striker 1 with replaceable ball indenter 2 with arm catch 3, working spring 5, barrel 5, arm pin 6, moving member of displacement sensor 7, body 8 with handle and funnel-shaped bevel 9 for release of striker, spring 10 for return of barrel in body, L-shaped levers 11, spring-loaded moving orientator 12 for direction test blow, electronic control unit 13 with adapter for fixing and indication of visual information of test results. Spring- loaded orientator has supporting rods 13, splined bush and spring. Striker catch unit includes catch axle, spring bush, catch spring and catch head. Electronic control unit is made up of sections to form an analogue signal which is proportional to displacement of probe into recess resulted from sclerometric blow, analogue-digital converter integral with digital indication section, voltage converter section. Instrument is used by holding it in one arm. It is applicable for testing undulated surface. EFFECT: high efficiency. 3 cl, 5 dwg
