Sampling device for liquid metals, which device contains a pipe (5) and a head (1) fixed on an end thereof, wherein a sampling chamber (11) is formed, which head (1) contains a part (2) of fireproof material which partially limits the sampling chamber (11), which is provided with a supply orifice (12-46) to the sampling chamber and which is put in the pipe (5) with a narrow end (3) in such a way that the sampling chamber (11) is located entirely outside of the pipe (5) and at least one small cooling plate (9) forming at least a part of the wall of the sampling chamber (11) and thus also limits this sampling chamber, characterized in that the part (2) is made of a material that at least during the sampling offers a structure letting gas pass. |
