Abstract

L’invention se rapporte à un système (1) de détection de fuites au moyen d’un gaz traceur destiné à être relié à une sonde de reniflage pour le contrôle de l’étanchéité d’un objet à tester, comportant un premier dispositif (13) de pompage permettant d’obtenir un vide primaire. Selon l’invention, le premier dispositif (13) de pompage comporte au moins une pompe à membrane formant au moins deux étages (E1, E2, E3, E4) de pompage reliés entre eux par un module (14) de connexion configuré pour sélectivement mettre chaque étage (E1, E2, E3, E4) de pompage en parallèle ou en série d’au moins un autre étage (E1, E2, E3, E4) de pompage en fonction d’un paramètre de fonctionnement du système (1) de détection de fuites.
