Abstract

See full text

A coin sensor comprising a first inductive branch with a first inductor in series with a first resistor; a second inductive branch with a second inductor in series with a second resistor, wherein the first and second inductors are arranged facing each other on both sides of a passage channel of coins to be discriminated; at least one capacitive branch with a condenser and a resistor in series; an excitation circuit with a generator and at least one pair of switches, configured to alternately feed the first inductive branch and the second inductive branch with a pattern signal with spectral energy in two or more frequencies, such that the branch of the inductor excited at any given time is arranged in a bridge configuration with at least one capacitive branch; at least one differential amplifier configured to alternately measure the voltage between the exit nodes of the excited bridge.
