摘要

The paper focuses on a high accuracy measuring hardness tester of universal use, meant to metals hardness tests using static loads and IMPACT ones. With this end in view, an electromagnetic loading computer-controlled system is used allowing the tested material to be stressed by a spherical tungsten carbide penetrator, and force is measured by a capacitive sensor which consists of an oscillation resonant circuit, and depth of penetration is measured by an inductive displacement sensor. To perform a certain hardness test using this equipment requires the penetrator change and proper computer setting only.
