Brahma Phototransistor FT13/R 18209058

The Brahma FT13/R is a phototransistor flame sensor with SKU 18209058. It is designed for flame detection in oil-fired and industrial burners, responding to visible or infrared radiation from a luminous flame. The sensor comes with a 600 mm cable and is used in flame detection circuits to signal the burner control of successful ignition.

When selecting a replacement phototransistor flame sensor, ensure the spectral range matches the flame type, and verify the response time, cable length, and connector type. The mounting sleeve or fitting must be compatible with the burner's observation port, so check the diameter and thread form. Confirm the overall cable length and physical mounting size before ordering.

Common failure modes include a contaminated or fogged window, an aged phototransistor cell producing a weak signal, or a damaged cable or sheath. When these occur, the burner control may fail to detect flame during the safety proving period, leading to a lockout. Check the sensor's window for cleanliness, test the signal strength, and inspect the cable for damage.
