Abstract
Apparatus for measurement of a temperature of a moving metal slab to provide a measured temperature indication corresponding to an actual temperature at a location on the surface of the slab. The apparatus comprises a first temperature measuring sensor mounted to move out of contact with a surface of the slab, and then into contact with the surface at the location, the first sensor generating an output corresponding to a detected temperature when the contact is made with the surface; at least one additional temperature measuring sensor mounted adjacent to the first sensor to move out of contact with the surface of the slab, and then into contact with the surface at the location, the second sensor generating an output corresponding to a detected temperature when the contact is made with the surface; and a comparator for determining whether or not the detected temperatures at the location differ by less than a particular amount, and for providing a measured temperature indication representing the actual temperature of the surface at the location based on one or more of the outputs, only if the detected temperatures differ by less than the predetermined amount. The invention also rela…
