Fonction
L'initiateur (contact NC) est intégré à un flotteur en PP et s'active en cas de déviation de sa position horizontale. La bille de commutation dans le flotteur bouge selon un axe et active le processus de commutation dans l'initiateur de façon inductive. La sortie de commutation fournie par l'initiateur prend la forme d'un signal de commutation conforme à la norme EN 60947-5-6 (NAMUR).
