Abstract

L'invention concerne un système de détection (900) pour la mesure de niveau de remplissage ou de niveau limite d'un produit de remplissage (55) ou la mesure de pression dans un récipient (50). Le système de détection (900) comporte un capteur (20) et un dispositif d'affichage (100) Le capteur (20) est conçu pour émettre et recevoir un signal de mesure et pour calculer des données de mesure. Le dispositif d'affichage (100) est séparé du capteur et comporte une unité de réception (110) qui est conçue pour la réception sans fil des données de mesure du capteur (20), et un affichage de signal (180) qui est conçu pour afficher les données de mesure du capteur (20).
