Abstract (en)
[origin: CA2261081A1] A capacitor sensor for assessing dielectric properties of currency paper uses a transmitting dielectrode on a first side of an evaluation channel and a receiving electrode on the same first side of the evaluation channel. A passive electrode is located on the opposite side of the evaluation channel and overlays with the transmitting and receiving electrodes. An electronic processing arrangement is connected to the transmitting and receiving electrodes and evaluates the signals for changes in the capacitance coupling of the electrode. This coupling is directly related to the properties of the paper passing between the passive electrode on one side and then transmitting and receiving electrodes on the other side.
