A cartridge (1) for purifying and/or drying compressed air in a compressed air processing plant (47), including a treatment system with a pre-filter, cyclone, coalescence filter and drying agent, has a sensor (38) for evaluating the operating condition of the treatment system. Independent claims are included for: (1) a compressed air processing plant (47) with a cartridge as above, an air processing circuit (48), a regeneration circuit (53), a control device for operation-dependent activation of the air processing and/or regeneration circuit and a receiver for data or signals from a transmitter in the cartridge; (2) a method for operating the compressed air processing plant, in which a measured value from the sensor (38) is monitored by the control device, and if this value (or a variant of the value) exceeds or falls below a threshold value, the control device (a) initiates regeneration operation, (b) adjusts regeneration operation, (c) generates a signal for exchange of the cartridge, (d) initiates compressed air processing operation and/or (e) adjusts compressed air processing operation; and (3) a variant of the compressed air processing plant, with: a cartridge having a treatment system as above, which adjusts the physical properties of the compressed air in an air processing circuit; a regeneration circuit, in which the compressed air is pretreated for further processing; and a control device to control or regulate alternation or the ratio between the processing and alternation circuits; the novel features being that (i) the air fed through the cartridge contacts a moisture evaluation sensor at the outlet side of the cartridge and (ii) the controller determines, in dependence on the air moisture content, one or more of the operability of the cartridge and the necessity for initiation or termination of regeneration or processing operation. Die Erfindung betrifft eine Kartusche (1) für eine Druckluftaufbereitungsanlage (47) eines Kraft- oder Nutzfahrzeugs. Erfindungsgemäß ist in der Kartusche (1) ein Sensor (38) angeordnet, mit dem beispielsweise eine Feuchte eines Behandlungsmittels der Druckluft, insbesondere eines Granulats, sensiert wird. In einer Steuereinrichtung (56) erfolgt nach Maßgabe des Signals des Sensors (38) eine selbsttätige Umschaltung zwischen einem Druckluftaufbereitungskreislauf (48) und einem Regenerationskreislauf (53). Hierdurch können sowohl die Phasen für die Druckluftaufbereitung als auch für eine Regeneration des Behandlungsmittels optimiert werden.
