FIELD: measurement equipment.SUBSTANCE: device comprises a heat element (8) made as a cable with mineral insulation. At the same time the heat element (8) is at least partially placed in a discharge pipe (10) stretching out of the liquid reservoir. In the device there is a tubular cartridge (26) soldered on a partial section with the heat element (8) and surrounding the heat element (8). There is a sealing device (2) provided to act as a pressure barrier. The sealing device (2) has a connection element (31) with the middle part surrounding the tubular cartridge (26) and resting against the tubular cartridge (26), and also a connection section (32) protruding at the sides and covering the discharge pipe (10) on the side of high pressure. The connection section (32) placed on the side of high pressure is connected via a screwed connection (36) with the discharge pipe (10), and the discharge pipe (10) due to a circular gap (42) is arranged at the distance from the tubular cartridge (26) and the heat element (8).EFFECT: provision of reliability of filling level indication.10 cl, 2 dwg |
