Product Overview

C7061A (spare code L28490P05) is a self-checking ultraviolet flame detector for industrial combustion systems. It detects UV radiation emitted by gas, oil and coal flames, sending flame presence signal to matched flame safeguard amplifier. Built-in oscillating shutter performs automatic self-diagnostic test during operation to ensure sensor reliability. Widely applied in industrial boilers, process heaters, furnace and power plant burner management systems. Discontinued legacy flame safety device; surplus and refurbished tested spare detector for burner system maintenance projects.

Application Notes

• Align detector viewing angle to flame zone for reliable detection.
• Periodically clean quartz window to maintain optical performance.
• Perform full flame failure response test after installation.
• Typical deployment: Industrial burner UV flame detector spare-part stocking.
