Description
The Brahma FT13/V phototransistor, SKU 18209106, is a flame sensor designed for precise control of gas burner valves. It detects visible and near-infrared light from flames in oil-fired and industrial burners, converting it into an electrical signal for combustion proof. This model features a 1200 mm cable length and durable insulation, suitable for direct flame viewing. It is placed outside the combustion zone in a mounting sleeve.

Choosing and fitting
Parts of this type are selected by matching the spectral response range to the flame's light output, response time, connector type, and physical mounting sleeve. The cable length must reach from the mounting location to the control box without splicing. Ensure the sensor is correctly aligned and the window remains clean during installation.
Signs of failure
Typical failures include a contaminated or fogged window reducing sensitivity, an aged cell yielding a weak signal, or a broken sheath exposing the cable to heat and moisture. When such failures occur, the burner control may not detect the flame, leading to lockout or improper operation. Check the sensor's window cleanliness and cable integrity.
