A Comprehensive guide to Flame 
Sensor
Introductio
n
A flame sensor is a safety 
device used in heating systems 
to detect the presence of a 
flame. It ensures the burner is 
operating correctly by 
verifying that the flame is lit; if 
no flame is detected, it shuts 
off the fuel supply to prevent 
gas leaks or explosions.
Why Flame Sensors 
Matter?
Flame sensors matter 
because they ensure safety 
by detecting flames and 
shutting off fuel in case of 
failure, preventing gas leaks, 
fires, and explosions.
