。[Claim for Utility Model Registration] A gas sensor that utilizes changes in the resistance of metal oxide semiconductors is installed in the flow path of exhaust gas from combustion equipment that has a burner and a heat exchanger to detect incomplete combustion. In the device, the gas sensor has an output peak at a specific temperature and decreases on both sides of the peak temperature, and a temperature sensitive resistor having a positive temperature coefficient of resistance;
A combustion safety device characterized in that it is configured to compensate for temperature dependence of the output of a gas sensor by combining a temperature-sensitive resistor having a negative temperature coefficient of resistance.
