The dilatometer (1) has a sample holder including a pair of clamping pins (4, 14) for receiving and clamping a metallic sample (3), and an induction coil (5) arranged on the metallic sample, where the induction coil heats the metallic sample. A sensor i.e. thermocouple, exactly measures temperature of the metallic sample in a region of a measuring plane of an optical measuring device. The optical measuring device detects change in length of the metallic sample in the measuring plane, and has a transmitter (6) and a receiver (9). |
