An apparatus (1) for detecting mechanical features of materials, in particular metal materials, comprising an indenter (10) adapted to be pushed against a sample material (15) in which it penetrates for a depth (h) and responsive to the hardness of the materials same. The apparatus (1) provides means for generating a measured force (F) and a transmission gear (35) which changes the rotational motion of shaft (40) of motor (30) into a linear reversible movement. The force generated is then amplified in a hydraulic way and transmitted to the indenter (10). This solution allows to lighten and to reduce the size of the mechanisms for generating the force, reducing also wear and mechanical backlash, as well as costs and overall dimensions. An advantage is also to measure with precision the stroke of the indenter with corresponding control in precision of the penetration (h) of the indenter in the sample material. |
