ABSTRACT:
A safety equipment for a gas burner is disclosed wherein a combustion sensor comprising an oxygen concentration cell having porous electrodes disposed on both sides of a sintered body of ion conductive solid electrolyte, is provided, so that incomplete combustion and extinction of the burner are detected by a change in e.m.f. of the sensor and a change in resistance of the sensor. The detected signal is used to block the feed of fuel to the burner in order to prevent CO gas poisoning and explosion.
