What is a Photocell?

Photocells are designed to detect the characteristics of the burner, coupled with a suitable flame controller to produce a signal. That signal then issues a response, which allows the system to continue to run in the presence of a flame, or to shut it down in a suitable manner in the absence of a flame.

Photocells are generally only used on commercial and industrial oil burners where a “fail safe” sensor is required. Well-adjusted gas flames may not emit sufficient light for a photocell to work.

The following rules apply to the application of rectifying photocells:

  • The photocell must have a good view of the flame.
  • The photocell must be protected from the light emitted from hot refractory.
  • Temperature at the photocell must remain under 165oF.
  • Proper lead wire must be used for the flame lead.
