The Fireye 65UV5 flame scanner is a microprocessor based flame scanner utilizing an ultraviolet tube-type sensor and an electro-mechanical self-checking shutter mechanism. The Fireye 65UV5 flame scanner incorporates an internal flame relay with a fixed ON/OFF threshold thereby eliminat- ing the need for an external flame amplifier.

The 65UV5 industrial flame detector is available with a one-second or four second flame failure response time (FFRT) depending on the model selected. The “E” versions are one second FFRT, the non-”E” versions are four seconds FFRT. The Fireye 65UV5-1004QD, -1004EQD flame scanner provides an analog 4 to 20 mA output referenced to flame signal strength.

The Fireye 65UV5 industrial scanner is powered from a 24 Vdc power source provided externally and includes an integral 8 pin quick disconnect connector. A color-coded internal LED indicates flame status and alarm condition. This can be viewed through a viewing port on the rear cover.

The 65UV5 housing has a NEMA 4X / IP66 rating. The unit is suitable for use in Class 1, Div. 2 haz- ardous environment groups A, B, C & D or Ex II3 G/D Ex nA IIC T4A.

65UV5 CEX models are wired directly via a terminal rail located within the CEX housing. Suitable glands must be used to terminate the cable at the housing.

Note: The 65UV5-1000, -1000E scanners became obsolete in 2008, and were replaced by the enhanced capability of the 65UV5-1004 and -1004E scanners. The 65UV5-1004QD and -1004EQD models with electrical quick-disconnect have replaced the original models equipped with ten feet of captive cable. 

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.
