48PT2 Infrared Flame Scanner

The 48PT2 lead sulfide infrared scanner contains a low impedance detector and is designed to detect low flicker frequency IR signals from gas and oil flames. It is designed for use on
DSeries, Flame-Monitor, FlameWorx and MicroM controls.

UV Flame Scanners

The UV1A3/6, UV2/UV2A6/UV2C, 45UV2, 45UV3, UV90-3/6/9 Scanners are used with the
M-Series, M-Series II, MicroM, FlameWorx, MB-2 and D-Series controls as well as the Fireye
FLAME-MONITORTM, BurnerLogix and Nexus System. The UV1A3/6 scanners come with 3 ft. and
6 ft. shielded flexible cables. The UV2 scanner comes with 36 inch (915mm) shielded flexible cable.
The UV2C comes with 36 inch (915mm) unshielded lead wires. The UV90-3/6/9 is available with 3
ft., 6 ft. and 9 ft. shielded flexible cables.
The UV8A Scanner is a 90° right angle ultraviolet flame scanner used in conjunction with the
M-Series, M-Series II, MicroM, FlameWorx, MB-2 and D series controls as well as the Fireye®
FLAME-MONITORTM, Burner Logix and the Nexus System. It is available only with 72 inch
(1830mm) unshielded lead wires.
The 45UV2 Scanner is a non self-checking scanner in a die cast aluminum housing with a 1 inch
NPT threaded mount.
The 45UV3 Scanner has a rugged cast housing that mounts on a 3/4 inch pipe with sleeve and setscrew.
The replaceable UV tube is mounted in a vertical position for greater sensitivity. Non selfchecking.
The UV90 Series Scanners are designed for front and lateral (90°) mounting which, in some applications
allow the scanners to obtain a clearer view of the flame. The UV90, with its exclusive snug-fit
mounting block, eliminates the need for a threaded sight pipe.
The UV tube is made of quartz and is filled with a gas that ionizes when struck by UV radiation from
the flame. In the absence of UV radiation, the gas acts as an insulator between two electrodes which
are mounted inside the tube. These electrodes are energized continuously by a high voltage. During
combustion, UV radiation ionizes the gas, causing current pulses to flow between the electrodes.
These current pulses result in a flame signal which is transmitted to the amplifier in the control,
where it is processed to energize or hold in the flame relay.
