Abstract

Inventia se refera la un sclerometru electromagnetic cu recul, destinat încercarilor nedistructive ale rocilor si betoanelor, pentru determinarea rezistentei la compresiune. Dispozitivul este format dintr-un electromagnet cu plonjor, care apasat pe suprafata de încercat un arc elicoidal se comprima si niste întrerupatoare normal deschise comanda un tiristor care închide circuitul de alimentare al electromagnetului. Plonjorul lovind suprafata cu forta maxima, decupleaza mecanic un întrerupator normal deschis ce comanda un tiristor, care decupleaza electromagnetul urmînd reculul. înainte de încercare, etalonarea aparatului se face pe un bloc de otel, reglînd intensitatea curentului electric, respectiv forta magnetomotoare cu o rezistenta înseriata cu electromagnetul.
