Gas burner flameout alarm circuit diagram

Published:2011/3/29 21:25:00 Author:Jessie | Keyword: Gas burner, flameout alarm

Figure 1 circuit is another kind of gas burner flameout alarm. After the gas burner normal burning, closing the power switch K. Because photoconductive resistance LDR is intenseirradiated , its value is very small, transistor BG1 and BG2 connected, relay J suck close, its closed contacts J - 1 disconnected, music integrated block IC has no sound. But once the gas burner stall, light irradiation abated, its value increases, BG1 and BG2 stop, relay J released, J - 1 closed, the power automatically connected, IC works, the speaker Y music warning issued, remind master promptly shutting gas valve.   (View)
