Abstract

The invention can be used in device for a detection of a level of a heat carrier in a reactor. The aim of the invention is to increase the data processing accuracy of a measure. The device comprises an elongated body (1) in which heated thermoelectric measuring instruments are arranged longitudinally. An unheated auxiliary thermoelectric measuring instrument of the cable type (4) is placed between seams (12, 13) of the measuring instrument. This makes it possible to continuously measure the temperature of the heat carrier. In other variant of the device, differential thermoelectric measuring instruments of the cable type (19, 20) are arranged longitudinally inside the elongated body (1). An unheated auxiliary thermoelectric measuring instrument (21) is placed between the ends of said measuring instruments. 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 thermoelectric measuring instruments (2, 3, 4, 5) in the mounting areas consisting of the seals and the covers (26) of the heating elements (16, 17) connected to an inner surface of the body (2) by the means of soldered joints (7). 20 claims, 13 figures
