<p>The device for detection of a level of the heat carrier in a reactor comprises an elongated body (1) in which heated thermoelectric measuring instruments (2, 3) are arranged with separated heated junctions (7). An unheated auxiliary thermoelectric measuring instrument (5) whose unheated junction (8) is placed in inner area, where the heated thermoelectric measuring instruments (2, 3) are arranged. The device also comprises the electric heating system (6) for heated junctions (7) of the heated thermoelectric measuring instruments (2, 3), additionally there is arranged at least one unheated auxiliary thermoelectric measuring instruments (4) whose junction (12, 13) is placed between heated junctions of the heated thermoelectric measuring instruments (2, 3). A system for electrically heating the seals of the thermoelectric measuring instruments is embodied in the form of discreet heating elements (16, 17) connected in series by cables (15). The covers (9) of the each thermoelectric measuring instruments (2, 3, 4, 5) in the mounting areas consisting of the seals and the covers of the heating elements (16, 17) connected to an inner surface of the body (1) by the means of soldered joints.</p> |
