Abstract (en)
[origin: EP0704825A1] The coin testing system has the coins (M) introduced into a channel section that is inclined such that the coins roll past a pair of inductive sensors. The channel is of a rectangular cross section and is tilted such that the coins move against one side wall that is ridged to facilitate motion. The inductive sensors have coils (9, 10) set into one side wall and metallic discs (11, 12) set in the other wall such that the coins pass in between. The sensors provide inputs to an electronic circuit (14) that measures the time response of the resistance of each one and determine maximum values. The circuit uses the values to determine the coin thickness.
