A flame sensing probe is a safety component used in gas burner systems to detect the presence of flame during operation. It works based on the ionization principle, where the flame conducts a small electrical current.
When a stable flame is present, the probe detects the ionization signal and sends confirmation to the burner controller. If the flame is lost, the control system immediately shuts off the fuel supply to prevent unsafe conditions.
Flame sensing probes are commonly installed in industrial boilers, furnaces, ovens, and other combustion systems. They provide fast and reliable flame monitoring to maintain safe and efficient burner operation.
