65UV5 INTEGRATED FLAME SCANNER Bulletin CU-104
WITH INTERNAL FLAME RELAY
The 65UV5 flame scanner is a micro-processor based flame scanner that incorpo-
rates an internal single pole, single throw (normally open) flame relay with a fixed
on/off threshold to provide flame on/flame off indication, eliminating the need of
an external flame amplifier. The scanner utilizes an ultra-violet tube type sensor,
and electromechanical self-checking shutter mechanism. The housing has a NEMA
4X / IP66 rating and is suitable for use in Class I Division II, Group A, B, C & D
“hazardous environments”. Models are available with a 4-second or a 1-second
flame failure response time (FFRT).
The Fireye 65UV5 flame scanner is powered by 24 vdc and includes an integral 10-
foot (3 meter) eight-conductor cable with cable gland. A two color internal LED
indicates flame status (off/on) and alarm condition. This can be viewed through a
viewing lens on the rear of the housing. The scanner provides an analog 4-20mA
output for remote indication of flame signal strength.
Fireye 65UV5 self-checking scanners are used to detect ultraviolet emissions from
fossil fuel flames such as natural gas, coke oven gas, propane, methane, butane,
kerosene, light petroleum distillates and diesel fuels.
