| 摘要 |
The invention relates to an insertion probe for determining the phase transitions of a sample taken from a steel melt by thermal analysis, having a measurement head comprising an immersion end, in which a sample chamber comprising an inlet opening and a thermoelement having the hot solder location thereof extending into the sample chamber are disposed, and comprising a cable penetration for signal cables of the thermoelement, wherein the cable penetration exits out of an outlet opening at an end of the measurement head opposite the immersion end, and wherein a line between the immersion end and the outlet opening forms a longitudinal axis of the measurement head, wherein a virtual plane is formed perpendicular to the longitudinal axis at each of the hot solder location and the part of the inlet opening furthest away from the immersion end, and that a) either the measurement head comprising a density of at least 6 g/cm3 between the immersion end and the plane furthest away from the immersion end, or that b) the measurement head comprises a density of at least 6.5 g/cm3 between the immersion end and an auxiliary plan formed at a distance of at least 10 mm from the plane furthest away from the immersion end and parallel to the same. |
