Brahma Photocell FC7/R 18210011

The Brahma FC7/R photocell, SKU 18210011, is a flame sensor used to detect the presence of a luminous flame in burners. It features a 1200 mm cable and durable insulation. This model is designed for precise control of gas burner valves, providing opening and closing when voltage is applied. It is suitable for oil-fired or industrial burners where flame luminosity is a key indicator.

When selecting a replacement photocell of this type, ensure the detection principle (UV or IR response) matches the burner control's requirements. Verify the spectral range, cable length, and connector type. The physical dimensions of the mounting sleeve must be compatible with the existing sight tube. Confirm that the cable length is sufficient to reach the control box without splicing, and that the signal output type and response time align with the burner control specifications.

Typical failures include a contaminated or fogged window, an aged cell producing a weakened signal, or a broken cable sheath. Symptoms may include the burner failing to ignite, intermittent flame detection, or the control board not detecting a flame signal. Check that the window is clean and the mounting sleeve is clear of soot or debris. A slow or intermittent response may indicate a mismatch in spectral sensitivity or a faulty control board.
