This roller comprises a thermocouple (39), delivering a signal in voltage which is converted, by conversion means (86) on board the roller, into a constrained current of value independent of the resistance of the output circuit. The constrained current is transmitted to the stationary part of the measurement circuit by an assembly (90) comprising rotating rings/stationary collectors. These conversion means (86) are disposed in a casing (54) of the roller and are fitted with air cooling means. The air is channelled into the casing (54) by supports (78,79,80) and annular frameworks (87,88,89) carrying the conversion means (86). …<??>Application to measuring the temperature of flat products passing through a continuous annealing furnace. …<IMAGE>… |
