ABSTRACT:
In a high-temperature probe (1) which is used in particular in a hot-gas flow (24) up to about 1550.degree. C., a sensor tube (19) and a support tube (6) are in each case arranged in an inner bore (2a, 2b) of a probe tube (2). The bore (2a) for the sensor tube (19), in which a temperature sensor (34) is arranged, ends in a throughflow passage (3b) for the hot-gas flow (24). The bore (2b) for the support tube (6) ends in an enlarged bore (4) of the probe tube (2), in which enlarged bore (4) a ring (8) of the support tube (6) is arranged. The support tube (6) and the sensor tube (19) project through bores (12a, 31a) of a flange (13) into a region called the plenum (27), a screw (18) being screwed in place in an internal thread (11) at the tip (28) of the support tube (6). A preloaded spring (17) which holds the high-temperature probe (1) together in a flexible manner sits between this screw (18) and a flange (14) which is connected to the flange (13) via a tubular socket (12).
