C7027A, C7035A, C7044A
MINIPEEPER ULTRAVIOLET
FLAME DETECTOR
THE C7027A, C7035A, AND C7044A DETECT ULTRAVIOLET
RADIATION EMITTED FROM ALL FLAMES. THEY ARE USED
WITH FLAME SAFEGUARD CONTROLS TO PROVIDE SUPER-
VISION FOR GAS, OIL, OR COMBINATION GAS-OIL
BURNERS.

l The C7027A, C7035A, and C7044A are used with the
following:
-Flame Safeguard Programmers/
Amplifiers
R4126 and R4127lR7255B
R4140IR7249A
R4150IR7259A
R4795lR7290
-Flame Safeguard Primary Controls/
Amplifiers
R4075C,D,E/R7249A
R4136C,D/R7249A
dA690G Protectorelay Primary Control
-R7023C Flame Detector Relay.
l The C7044A is also used with the following 50’ Hz Flame
Safeguard Controls/ Amplifiers:
R434l /R7323
R4343lR7323
R4344IR7323
l The C7027A mounts on a 1 I2 in. sighting pipe by means of an
integral collar.
l The C7035A mounts on a 1 in. sighting pipe by means of an
integral collar. A shield protects the sensing tube.
l The C7035A meets outdoor raintight requirements of Under-
writers Laboratories Inc., NEMA 3, and NEMA 4.
l The C7044A mounts with a simple, l-screw bracket. Sensing
tube enclosed in stainless steel housing.
l The C7044A is suitable for side or end viewing.
l Compact size makes the C7027A and C7044A particularly
useful for blast tube mounting.
l Properly installed, the C7027A and C7035A are sealed
against pressures as high as 5 psi 134.5 kPa].
l The C7035A ultraviolet sensing tube is field replaceable. The
C7027A and C7044A sensing tubes are not field replaceable-
use on an economical, throwaway basis.
l Two Minipeeper detectors can be wired in parallel for difficult
sighting applications.
