The probe (3) comprises a measurement and sampling part (10) mounted on a tube (11, 12) which fits with some grip over the lower narrowed end (8) of the immersion lance (2). An elastic ring (13) surrounds a narrowed end of the part (12) said tube (11, 12) and is pressed between a stop shoulder (9), formed by the transition from the narrowed end (8) to the broader part of the lance (2), and a shoulder (16) formed by the transition of the narrowed end to the broader part of part (12). The ring (13) tightens the split between said shoulder (9) and the end of part (12) so that no burr of solidified metal or slag can be deposited at this place, also during a vibrating movement of the probe (3) with respect to the lance (2). |
