Abstract
A device for the extraction of gaseous samples and for thermal measurement above the burden of a shaft furnace includes at least one probe arm resonantly positioned in a horizontal plane above the burden. Means are provided for pivoting the probe arm above the burden from a rest position juxtaposed the furnace wall so that the entire surface of the burden can be scanned.

A device for the extraction of gaseous samples and for thermal measurement above the burden of a shaft furnace, the device comprising at least one probe arm permanently positioned in a substantially horizontal plane above the burden;
- a series of apertures distributed over the entire length of the probe arm and conduits communicating separately with each of the apertures and with the exterior of the furnace;
- and means for pivoting the probe arm from a rest position juxtaposed the inside wall of said shaft furnace across and above the burden in such a way as to scan practically the entire surface of the burden, said pivot means having at least one pivot axis juxtaposed the inside wall of said shaft furnace.
