C7915A Infrared Flame Detector
APPLICATION
The C7915A Flame Detector includes a lead sulfide photocell
that is sensitive to the infrared radiation emitted by the
combustion of fuels such as natural gas, oil, and coal.
• Particularly suitable for combination or dual-fuel
applications.
• When installed properly, can supervise the pilot flame and/
or the main burner flame.
• Mounts easily on a standard 3/4 inch sight pipe.
• The infrared sensor plugs into an electrical socket in the
C7915A assembly and is field replaceable.
• The lead sulfide photocell’s sensitivity to infrared radiation
is compatible with a wide range of flame supervisory
applications.
• Flexible metal cable protects and electrically shields the
detector coaxial cables.
• Accessories available include a heat block, seal-off
adapter, reducer bushing, and orifice plate.
• Immune to x-ray testing.
SPECIFICATIONS
STANDARD MODELS
MODELS: See Table 6 for flame safeguard controls and asso-
ciated amplifiers.
DETECTOR RESPONSE: Responds to infrared radiation with
wavelengths between 0.75 and 1.0 micron.
LEAD SULFIDE PHOTOCELL: Photo conductor resistance
decreases as incident radiant energy increases.
AMBIENT TEMPERATURE RATING: -40°F to 125°F (-40°C to
52°C) maximum at the lead sulfide photocell.
