Abstract
The probe comprises a support in the form of a sheath, a series of internal pipes, retained by spacers and connecting orifices distributed along the sheath to a device for measuring and for receiving the gas samples outside the furnace, and thermocouples arranged at the level of the said orifices. In order to enable the pipes to be replaced without disassembly of the probe, the said orifices are situated in steps provided in the sheath, while the internal pipes, for taking gas samples and heat measurements are all individual, straight and exchangeable elements housed in straight support and protection channels, each traversing the sheath from the outside as far as the respective step.
