FLAME EYE A524-273-7000-4 MIURA Marine Boiler Flame Sensor
The FLAME EYE A524-273-7000-4 MIURA (Model / Part No: A524-273-7000-4, Miura Code: A524-273-7000-4) is a heavy-duty photoelectric optical flame detector sensor unit manufactured for Miura marine auxiliary boilers and industrial steam generators. Designed to continuously monitor optical flame radiation inside burner combustion chambers, this flame eye sensor transmits instant flame signals to the primary safeguard control relay to ensure automatic burner firing loops and prompt fuel isolation upon flame loss.
Constructed with high-sensitivity optical sensor elements enclosed in a heat-resistant and oil-tight casing, the A524-273-7000-4 operates reliably under intense furnace radiation, elevated ambient temperatures, and continuous engine room vibration. Installed across Miura marine boilers, shipboard incinerators, and thermal fluid plants, it provides accurate flame presence verification, preventing dangerous unburned fuel accumulation.
