WebA flame sensor is a crucial safety component on your gas heating system. During the ignition cycle, your gas furnace goes through a process where a spark or a hot surface ignitor will actually ignite the gas. As the gas is ignited, the flame sensor creates a current of electricity. The electricity is calculated in micro amps.

"The intense ionization within the body of a flame can be measured by means by the phenomena of flame rectification whereby an AC current flows more easily in one direction when a voltage is applied. This current can be used to verify flame presence and quality. Such detectors can be used in large industrial process gas heaters and are connected to the flame control system. They usually act as both flame quality monitors and for flame failure detection. They are also commo… " - Flame sensor vs thermocouple
