The SPOT actuator provides remotely controlled target alignment of a SPOT pyrometer for improved accuracy in temperature measurement for aluminum processing applications. The motorized unit is designed for use at the billet reheat furnace exit, die entrance and exit, and quench exit on aluminum extrusion presses. The actuator is capable of operating in automatic or operator-controlled modes to suit the needs of an individual aluminum plant. It enables extremely accurate alignment, as it takes 900 measurement points over 90 degrees and aligns on the optimum measurement position on the profile.
