<p>A liquid metal level inductive indicator comprises a cooled cylindrical casing (1) having a bottom (2) and a cap (3) and mounted inside a jacket (4) forming, together with the walls of the casing (1) a cavity for circulation of a refrigerant, an open U-shaped magnetic circuit (5) with working and measuring windings (6, 7) which is mounted inside the casing (1) and is fixed on a non-magnetic plate (8) with its butt-ends (9) close to the bottom (2) of the casing (1), an additional open U-shaped magnetic circuit (11) with working and measuring windings (12, 13) connected electrically with the working and measuring windings (6, 7) of the open magnetic circuit (5). The additional open magnetic circuit (11) is placed between the cap (3) of the casing (1) and the non-magnetic plate (8) in the same longitudinal plane as the open magnetic circuit (5) and is movable along the longitudinal axis of the casing (1). </p> |
