Abstract
Optimization of the speed of production and the control of quality of extruded aluminum products requires the measurement of the temperature of the extruded product during processing. This temperature measurement should be by a non-contact sensor placed as close as possible to the extrusion die, and the measurement should be accomplished and reported with sufficient rapidity to be used in a feedback control loop. For this purpose, an eddy current sensor which performs an on-line measurement of resistivity and converts the measurement to the corresponding temperature has been developed. This project is being conducted jointly by The Aluminum Association and the National Bureau of Standards.
