Bard HVAC 8554-016BX Flame Sensor 18" Lead

The Bard HVAC 8554-016BX Flame Sensor is a fire detection component that monitors the presence of combustion within heating equipment. It uses an 18-inch lead wire to transmit the flame signal from the sensing element to the control circuit. The sensor detects flame rectification during burner operation and converts it into an electrical signal for monitoring purposes. Commonly applied in furnaces, rooftop units, and gas-fired heating assemblies in HVAC systems, it contributes to burner monitoring and ignition feedback within the combustion section. Positioned near the burner area, it supports flame detection and signal transfer between the sensing point and related control circuitry.
