C554A
Cadmium Sulfide Flame Detector
APPLICATION
The C554A Cadmium Sulfide Flame Detector (cad cell) is a
photoconductive flame detector used with oil primary
controls such as R4166, R4184, R8182, R8184, R8185, R8404
and R8991.
FEATURES
• Cadmium sulfide sensing element provides faster
response than bimetal sensors.
• On flame failure, the cad cell causes the oil primary
control to shut down the main burner.
• Mounting brackets available to fit all applications.
• Entire cell is hermetically sealed (glass to metal) to reduce
cell deterioration by humidity, soot, or oil fumes.
• Plug-in cell for easy replacement.
• Recessed cell provides more accurate flame sighting and
prevents accumulation of dirt and soot on cell face.
