<p>Device for obtaining mechanical characteristics of coins, comprised of an element which is elastically deformable by the weight of coins during their passage on said element. The deformation of said element will depend on the weight of the coins and their position on the length of said element. The elastically deformable element is provided with sensors in order to obtain an electric signal inherent to the mechanical characteristic searched in the coin. From the impact produced by the drop of the coins on said beam a parameter representative of the mechanical elasticity of the coin is determined by means of frequency analysis, by proceeding to the measurement of higher harmonics of the impact signal.</p> |
