Brahma Phototransistor flame sensor FT13/V 18209114

The Brahma FT13/V phototransistor flame sensor (SKU 18209114) is an original Brahma part designed for flame monitoring in diesel burners. It uses a phototransistor to detect visible and near-infrared light emitted by the flame, ensuring safe operation by signaling the control unit to shut off fuel supply in the absence of flame. This sensor is suitable for oil and industrial burners and comes with a 350 mm cable. It is manufactured in Italy and is currently marked as unavailable for ordering.

Parts of this type are selected by detection principle, spectral sensitivity, response time, cable length, connector type, and the mounting sleeve required. The sensor must be mounted with a direct line of sight into the combustion zone, and the mounting position must be exactly as the original to avoid misalignment. Before ordering, compare the connector type and cable length with the existing part, and verify that the cable length is sufficient to reach the burner control without straining the connection.

Items of this kind can fail due to soot or oil residue on the lens window, which weakens the signal and can cause nuisance lockouts. A cracked or fogged window reduces light reaching the phototransistor and may trigger a safety shutdown even when the flame is present. Aging cells can lose sensitivity over time, producing a weaker output that the control box no longer recognizes as a valid flame signal. Check the condition of the sensor window and sealing grommet during replacement.
