<p>The apparatus has a temperature probe mounted on a tubular measuring unit (1) and immersed in a process vessel by a beaker-type metallic protective pipe (2) that is enclosed by a container wall (8). The protective pipe touches a base at a point of contact (3), where the protective pipe outside the process vessel is sealed by a connection head (6). The protective pipe and the measuring unit are made of different thermoelectric materials and are connected with a head transmitter (11) for supplying thermal voltage in the connection head.</p> |
