ABSTRACT:
In a temperature measuring circuit connecting a temperature sensor such as a thermistor to a standard voltage source through tap resistances, detecting a sensed value of the temperature sensor by comparing the voltage of the sensor connecting point with the specified voltage by a comparator, a simplified construction of the circuit makes it possible to detect failures of the temperature sensor such as breakage or burn-out.
