Abstract

L'invention porte sur un commutateur de niveau d'eau électronique, pour la commande automatique d'une pompe, qui comprend un capteur de niveau d'eau (1) et une carte de circuit imprimé de commande (2) pour effectuer une commutation entre un état d'arrêt et un état de démarrage de la pompe par la réception d'un signal d'essai du capteur de niveau d'eau (1). Deux électrodes sont amenées hors du capteur de niveau d'eau (1). Une extrémité d'une première électrode (6) s'étend à l'intérieur d'une cavité de pompe (3) ou à l'intérieur d'un raccord de conduite, ou à l'intérieur d'une conduite. L'autre extrémité de la première électrode (6) s'étire hors de la cavité de pompe (3). Une seconde électrode est disposée à l'extérieur de la cavité de pompe (3), et est plus basse que la première électrode (10) dans une position horizontale. Le commutateur de niveau d'eau électronique améliore la précision de la commande de la pompe et réduit le taux de pannes de la pompe.
