4 Sec. FFRT Integrated Flame Scanner with 1" NPT Mounting Flange

The 65UV5 flame scanner is a micro-processor based flame scanner that incorporates 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 a 24 vdc. 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 4-20 mA 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.
