Brahma Photocell FC11/N 18210050

The Brahma FC11/N is a photocell flame sensor used in oil-fired and industrial burners to detect luminous flames. It operates by responding to visible or infrared light emitted by the flame, ensuring precise control of gas burner valves. This model has a cable length of 620 mm and is designed with high heat resistance and durable insulation. The sensor's stable design ensures consistent performance. It is manufactured in Italy and is identified by article numbers 18210050 and 246.901.012.

When selecting a replacement photocell of this type, verify the spectral response (visible or IR), response time, cable length, connector type, and physical dimensions of the mounting arrangement. Ensure the sensor has a direct line of sight to the flame, typically through a mounting sleeve or sight glass. Confirm that the mounting sleeve and viewing angle position the cell correctly to see the flame without obstruction. Cross-check the manufacturer codes with the existing part to ensure electrical and mechanical characteristics match the burner control.

Common failure modes for photocells of this class include a contaminated or fogged window that reduces light transmission, an aged sensing element producing a weakened signal, or a damaged cable sheath. When these occur, the burner may fail to detect the flame, leading to safety shutdowns or erratic operation. Check the sensor window for dirt or fogging, test the sensing element's output, and inspect the cable for damage.
