Abstract
Method and apparatus for monitoring the temperature of a resistor in a resistive current controller. The heating and cooling rates for the resistor are determined and a predicted temperature of the resistor is automatically calculated at the beginning each time interval of consecutive time intervals by subtracting from the previous temperature prediction for the resistor the product of the cooling rate of the resistor and the time interval and adding the product of the heating rate of the resistor and the time interval. An actuating signal is produced when the predicted temperature of the resistor for a given time interval corresponds to a threshold temperature.
