Abstract: An electronic timing system for timing a frying cycle of a fat frying apparatus includes means for adjusting the timing cycle for variations in the temperature of the fat or oil used in the fryer. The temperature adjusting portion of the system includes a thermistor mounted in a probe immersed in the fat or oil. The thermistor is one leg of a resistance bridge. The bridge is coupled across a comparator which senses the output voltage therefrom and generates an output signal which varies with temperature. This temperature-related output signal is compared in a second comparator with the voltage across a charging capacitor in a resistance-capacitance network. When the charging voltage from the resistance-capacitance network exceeds the temperature-related output signal, the second comparator generates a signal which indicates that the frying cycle is completed.
