Title
(EN) A FILTER, MORE PARTICULARLY LIQUID FILTER, PROVIDED WITH A FILTER ELEMENT WITH AN IDENTIFICATION LABEL
(FR) FILTRE, PLUS PARTICULIEREMENT FILTRE A LIQUIDE, POURVU D'UN ELEMENT FILTRANT PORTANT UNE ETIQUETTE D'IDENTIFICATION
Abstract
(EN)
A filter comprising a casing with an inlet space for liquid to be filtered and an outlet space for filtered liquid; a substantially cylindrical filter element of the disposable type, which is removably placed within the casing to function therein as a liquid permeable partition between the inlet space and the outlet space; a unique information containing micro circuit provided in said filter element, adapted to function as an identification label and cooperating with a receiver element provided in the casing, so as to provide for a periodical or continuous exchange of information between the micro circuit and the receiver element. According to the invention the micro circuit is embedded, at a circumferential location, in a sealing ring provided at a terminal edge of the cylindrical filter element, by means of which sealing ring the filter element sealingly engages an annular seat between the inlet space and the outlet space. The receiver element is provided in said seat and comprises a flat annular coil, the average diameter of which corresponds with that of the sealing ring.
(FR)
Un filtre comprenant une cartouche définissant un volume d'entrée pour le liquide à filtrer et un volume pour le liquide filtré. Un élément filtrant sensiblement cylindrique de type jetable placé amovible dans la cartouche pour y servir de paroi perméable au liquide entre le volume d'entrée et le volume de sortie. Un microcircuit porteur d'une information unique monté dans cet élément filtrant, conçu pour servir d'étiquette d'identification et pour coopérer avec un élément récepteur disposé dans la cartouche, de façon à assurer un échange d'information périodique ou continu entre le microcircuit et l'élément récepteur. Selon l'invention, le microcircuit est en inclusion, en un point de la périphérie, dans un joint d'étanchéité équipant le bord terminal de l'élément filtrant cylindrique, joint au moyen duquel l'élément filtrant établit une liaison hermétique avec un siège annulaire entre le volume d'entrée et le volume de sortie. L'élément récepteur, qui est disposé dans ledit siège, comprend un enroulement annuaire plat dont le diamètre moyen correspond à celui du joint d'étanchéité.
