Method for monitoring a filter element

(57) Summary book invention relates to the method and equipment for supervising the exchange component (1) which is attached to the composition unit and needs maintenance. The characteristic data of some characteristic data, i. E. , the geometric form of an exchange component (1), the physical characteristic and/or a function, or others -- the inside of an exchange component (1) -- and it is saved into/or the suitable memory configuration portion (5) prepared by touching. Furthermore, by suitable reading equipment, data is read into an evaluating unit in the time of a setup, or the time interval of a setup. This read data is compared with the data of a setup in an evaluating unit, and the interference to the function of an exchange component and/or a composition unit can perform it after the comparative evaluation of data.
