Honeywell Photocells & Detectors

The C7027A, C7035A and C7044A detect the ultraviolet radiation emitted by combustion flames. The flame detectors are used with Honeywell flame safeguard controls to provide flame supervision for gas, oil, or combination gas-oil burners.

• C7027A. C7035A, and C7044A Flame Detectors are used with R7249A, R7290A, R7749B and R7849A,B Amplifiers and the appropriate Honeywell controls
• C7044A may also be used with the following 50 Hz Honeywell combustion controls/amplifiers:
  R4341/R7323
  R4343/R7323
  R4344/R732
• C7035A has an integral collar threaded (internal l- 1 l-112 NPSM) for mounting on a one-inch sight Pipe
• C7035A housing meets Underwriters Laboratories Inc. requirements for raintightness and complies with NEMA enclosure standards, types 4 and 4X
• C7044A mounts with a two screw bracket. The UV sensor tube is enclosed in a stainless steel housing
• C7044A has the capability of side or end viewing in flame monitoring applications
• Because of their compact size, the C7027A and C7044A are particularly suitable for blast tube mounting
• Properly installed, the C7027A and C7035A are pressure rated for 5 psi
• C7035A ultraviolet radiation sensor tube is field replaceable
• Two C7027A, C7035A, or C7044A Flame Detectors can be wired in parallel for difficult flame sighting installations.
