Abstract

Dispositif de mesure de niveau utilisant des thermoéléments (20) qui sont disposés sur un support en forme de feuilles (25). Les thermoéléments (20) comprennent deux matériaux différents et sont agencés en deux séries côte à côte (71, 72). Deux thermoéléments (20), situés côte à côte, de ces deux séries (71, 72) présentent une zone de jonction commune (23) qui est chauffée. En outre, les deux séries (71, 72) de thermoéléments présentent deux autres zones de jonction mutuelles qui sont froides. Il est prévu un premier groupe de thermoéléments (20) qui sont disposés, avec leurs supports (25), à l'intérieur du récipient et qui fonctionnent comme des détecteurs de mesure. En outre, il est prévu un deuxième groupe de thermoéléments (20) servant de détecteurs de référence, du fait qu'ils règlent, par rapport à une tension de référence définie, le courant de chauffage alimentant les zones de jonction (23).
