Abstract
Pompe à vide (1) comportant un stator (2) comportant au moins un étage de pompage (T1-T5), deux arbres (4) portant des rotors (5) configurés pour tourner dans l’étage de pompage (T1-T5) autour d’un axe de rotation (I-I) respectif, au moins un carter d’huile (6) comprenant une chambre configurée pour contenir un lubrifiant liquide destiné à lubrifier des éléments (10, 11) permettant la rotation des arbres (4) et un dispositif de détermination du niveau de lubrifiant liquide (12) configuré pour déterminer une information représentative du niveau de lubrifiant liquide contenu dans la chambre du carter d’huile (6) à partir de la mesure différentielle de pression entre la pression exercée par le lubrifiant liquide et la pression gazeuse régnant dans le volume de la chambre du carter d’huile (6) au-dessus du niveau de lubrifiant d’huile.
