Patent

CA 2288657

The invention relates to a leak test for liquid-filled receptacles, in accordance with which a pressure difference Dp between the inside and the outside of the receptacle is established. The invention seeks to provide reliable information about the imperviousness of the receptacle and also of its walls, which are in contact with the liquid content. To this end, impedance measurement (7) is carried out on the outside of the receptacle by means of measuring electrodes (3a, 3b).

L'invention concerne le contrôle d'étanchéité de récipients remplis de liquide, selon lequel on établit une différence de pression .DELTA.p s'exerçant de l'intérieur vers l'extérieur du récipient. Dans le but de disposer d'une information fiable sur l'étanchéité existante, y compris celle en rapport avec la paroi du récipient en contact avec le produit liquide, on effectue, au moyen d'électrodes de mesure (3a, 3b), une mesure d'impédance (7) à l'extérieur du récipient (1).
