Abstract
(EN)
An electronic level sensor (1) includes a closed container (2), electrode membranes (31), and a common electrode (32). The closed container (2) is filled with conductive liquid (5) and has a bubble (4) formed by the air. The electrode membranes (31) and the common electrode (32) contact with the conductive liquid (5). The closed container (2) has extended slots (24) sealed by low temperature nanometer glass paste. The electrode membranes (31) and the common electrode (32) are formed on the inner surface of the closed container (2) by vacuum coating and extend toward the outer surface of the closed container (2) through extended slots (24).

L'invention porte sur un capteur de niveau électronique (1) qui comprend un contenant fermé (2), des membranes d'électrode (31) et une électrode commune (32). Le contenant fermé (2) est rempli par un liquide conducteur (5) et présente une bulle (4) formée par l'air. Les membranes d'électrode (31) et l'électrode commune (32) viennent en contact avec le liquide conducteur (5). Le contenant fermé (2) présente des fentes étendues (24) scellées de façon étanche par de la pâte à verre nanométrique à basse température. Les membranes d'électrode (31) et l'électrode commune (32) sont formées sur la surface interne du contenant fermé (2) par revêtement sous vide, et s'étendent vers la surface extérieure du contenant fermé (2) à travers des fentes allongées (24).
