BASO Gas Products Y75AH-1 Flame Sensor

The BASO Gas Products Y75AH-1 Flame Sensor is a flame-sensing probe used in gas-fired ignition systems to verify the presence of a burner flame during operation. It detects flame through electrical conductivity between the rod and burner ground, sending a signal back to the ignition control to confirm safe combustion. In HVAC systems, it is commonly installed in furnaces, boilers, and water heaters where continuous flame monitoring is required for gas operation. This ignition safety circuit, it helps prevent unburned gas release, supports burner sequencing, and ensures consistent operational safety in residential and commercial heating equipment.
