Abstract:
Level indicator for controlling the levels in a boiler or tank, comprising:a body member, comprised of a single-piece insulating material mold body, to be applied to a single hole of the boiler or tank in which the minimum and maximum level is to be monitored, said body being suitable for withstanding high pressures and temperatures; and two conductive material rods, partially sunk into said insulating material mold body, protruding at different heights from an upper end of the body in which said rods are inserted, each of said rods being provided, on the external surface in contact with said body, with a projection or a recess in order to strengthen coupling between said rods and the material of the body, wherein the coupling provides for a seal between the conductive material rods and the body so as to prevent the escape of the contents of the boiler or tank at the seal.
