Material Composition Thermoplastic flame retardant housing Ultraviolet photosensitive detection tube Tempered glass detection window Nickel-plated brass mounting thread Stainless steel terminal screws Rubber sealing washer
Structural Features Small cylindrical thermoplastic housing. Front tempered glass detection window. Rear terminal block connects supply and signal wires. Side mounting thread inserts directly into burner sight ports. Integral weather seal boot covers wiring terminals.
Working Principle Ultraviolet radiation from combustion flames passes through the detection window to illuminate the internal UV photosensitive tube. When the tube receives ultraviolet energy, it conducts, triggering the internal relay to actuate, outputting a “flame present” dry contact signal to the burner safety controller. When the flame extinguishes and ultraviolet radiation disappears, the photosensitive tube cuts off, relay releases, outputting “flameout” signal to trigger interlock shutdown.
Installation Requirements Screw the detector into the burner sight port, tighten to maintain seal. Align detection window directly at the pilot flame, no obstructions in line of sight. Tighten terminal screws for supply and signal wires. After power-up, perform a simulated flame test to verify detector output operation.
Usage Notes Dust buildup on the detection window reduces UV sensitivity; clean the window monthly for small burner installations. Never install the detector in locations exposed to direct sunlight, this causes false flame signals. Long-term operation above 60 °C shortens photosensitive tube service life. Never mount the detector in a position where the sight glass faces cold external air, condensation blocks UV transmission.
