点がある。 However, a temperature measuring device in which a temperature measuring device consisting of a power supply couple is inserted into the inner surface of the heat-sensitive part of a heat-resistant protection tube,
Temperature measurement This device is fixed in an upright position using a mounting bracket installed in a molten metal container, etc., and the heat-sensitive part is below the surface of the molten metal.Since it is fixed, there is no need to consider the specific gravity of the molten metal, and the molten metal can be removed from the container. Even if the liquid level fluctuates up and down due to waving or refilling, there is no floating that changes the distance between the bottom of the container and the heat-sensitive part, and the heat-sensitive part of the heat-resistant protection tube becomes deeper from the molten metal surface as the liquid level changes. or become shallower. However, since the temperature of the molten metal tends to drop from the liquid level, the relationship between the heat-sensitive portion of the heat-resistant protective tube and the molten metal changes with fluctuations in the liquid level, resulting in errors in the measured temperature.
