Abstract
The probe comprises a probe arm provided with a series of orifices for simultaneously taking gas samples and measuring the heat at different locations of the charging surface and penetrating through an opening in the furnace. This opening is surrounded by a support hoop integrally connected to the wall of the furnace and provided with two diametrically opposite outer journals on which are articulated two parallel arms supporting between them the probe arm. This arm can move about the center of the said hoop under the action of at least one actuator mounted between the said hoop and the outer end of the probe arm, the arm comprising a circular sliding surface moving, sealingly, over the inner surface of the said hoop.
