Minipeeper® Ultraviolet Flame Detectors
APPLICATION
The C7027A, C7035A, C7044A and C7927A Minipeeper®
Ultraviolet Flame Detectors 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.
FEATURES
C7027A, C7035A, and C7044A Flame Detectors are
used with RA890G devices or 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/R7323
C7027A has an integral collar threaded (internal
1/2-14 NPSM) for mounting on a one-half-inch sight
pipe.
C7035A has an integral collar threaded (internal
1-11-1/2 NPSM) for mounting on a one-inch sight pipe.
C7035A housing meets Underwriters Laboratories Inc.
requirements for rain tightness 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, C7035A and C7927 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.
C7927A is used with only the R7851B Flame Amplifier
and the 7800 SERIES controls.
C7927A has an integral collar threaded (internal
1/2-14 NPSM) for mounting on a one-half inch sight
pipe.
