Abstract
In a flame ionization sensor type gas combustion control apparatus, the sensor tip, or probe, exposed to the flame is constructed and arranged according to materials and shapes which promote mechanical deformation of the sensor due to thermal expansion and contraction. The mechanical deformation will cause cracks to open in the contaminant layers surrounding the probe, enabling the sensor to perform as intended even though insulative contaminant build up is present.
