Abstract
Temperature monitoring of electrically conductive wire during heating in which the current in the wire in the heating zone is measured and the voltage at the downstream end portion of the zone is measured, signals corresponding to the measured values then being combined to produce a resultant signal corresponding to the resistance of the wire at the downstream end portion of the heating zone. The resistance value corresponds to the temperature of the heated wire. Apparatus includes current and voltage measuring means located in the appropriate positions to enable temperature monitoring, and means to combine voltage signals which correspond to the measured values and to produce a combined signal representative of wire resistance after heating.
