2Workingprinciple andDiagram ofthe instrument
2.1 Workingprinciple
An impact bodywith a sphericaltest tip madeof
tungsten carbide ispropelled against thesample
surface by aspring force andthen rebounds back.
At adistance of 1mmfrom the samplesurface, the
impact and rebound velocity ofthe impact body,
when passing through the coilin its coilerholder,
induces in thecoil and electricvoltage proportional
to the velocities fo themagnet. Leeb hardness as the
