<p>A method and unit for detecting the surface temperature of a heating element (4) movable along a given path (P), whereby the infrared radiation (11) emitted by the heating element (4) is reflected onto a fixed external pyrometer (9) by means of a reflecting member (10) powered to rotate about a respective axis (14) to follow the heating element (4) and continue reflecting the infrared radiation (11) emitted by the heating element (4) onto the fixed external pyrometer (9) for a given length of time. <IMAGE></p> |
