Abstract

Contrôleur électrique de niveau avec avertisseur électronique de signalisation, adaptable au niveau à eau pour réglage optima de celui-ci. Contrôleur caractérisé par le fait qu'il est constitué par un bloc avertisseur vissable et tarable sur une fiole de niveau. Ce bloc robuste et étanche comporte un ampli, un signal sonore ou lumineux mis sous tension lorsque le liquide à contrôler ferme ou ouvre un circuit électrique par l'intermédiaire de deux électrodes. Il permet à une seule personne d'utiliser un niveau à eau d'une façon précise, sûre, en tous lieux, sur de grandes distances. Une pile, une sonnerie incorporées dans ce bloc rendent cet appareil indépendant et audible par la personne qui l'emploi sur un chantier important Système adaptable au contrôle de tous liquides ou solides contenus dans tous récipients, cuves, tuyauteries... Ce contrôleur de niveau électrique peut être adapté à toutes machines comportant un circuit hydraulique comme contrôleur de fuites et mise en sécurité de ces machines.
