  • the first, the second and the third sensor elements 25, 29 and 31 with locating circuit serve as path sensors.
  • the position of the sensor element 25, 29 and 31 with the locating circuit can be detected by way of the abovementioned transmission and reception coils (not shown) on the resonant circuit location system 32.
  • the operation of such sensor elements with locating circuit was explained in the introduction to the description. Deviating from the known use of the location sensor is now in the first sensor element with locating circuit 25 an RFID chip (not shown in detail) provided. Using this RFID chip can take place using the interaction between the resonant circuit location system 32 and the first sensor element 25 with locating circuit by a coded influencing the resonant circuit of the first sensor element 25 with locating circuit information exchange.
  • information about the state of the filling 27 can be made by measuring the filling level of the filling 27 via the first sensor element 25 with locating circuit.
  • the extent of such a filling 27 gives a measure of the loading state, so that in this way statements about the exhaustion of the filter cartridge can be made.
  • the third sensor element 31 with locating circuit can be used for a variety of purposes in the operation of the machine for control.
  • a detection of the consumption state, a Neufiltererkennung, a lifetime control and a water hardness calculation and many other state and / or operating data is possible.
  • the water hardness calculation could be determined, for example, based on the lifetime of the filter cartridge taking into account the flow rate.
  • a descaling notice of the beverage machine can be generated based on the thus acquired state and / or operating data. Machine use without a filter or with a wrong filter can also be detected so that warranty service and warranty claims may be coupled to the use of a correct filter if necessary.
  • the RFID technology allows for authenticity monitoring, possibly in conjunction with a lock on the machine when using an unauthenticated filter cartridge. It can take place a flow rate control and again a filter change detection.
  • the flow rate control requires the storage of the water flowed through the filter cartridge. This can be detected, for example, by a time measurement during the reference of water by the coffee maker 21.
  • the corresponding storage unit is preferably accommodated in the sensor system of the filter cartridge 24, so that these cartridge-specific data are also currently available for an interim replacement of the filter cartridge 24 and its renewed insertion.
  • Essential for the invention is a filter cartridge 3, which is equipped with a communication element.

Abstract
